Mr. Cox gave the first presentation on BOA2015 -006 by stating that the Applicant is requesting a variance to Section VI.B Number of Signs (General Provisions) and Article IX, Section 7.4 Wall Sign of Ordinance #96 -S -28 Unified Development Code as amended and adopted by the Enterprise Business Park PUD, in order to permit one 60 square foot secondary wall sign with logo /letters not to exceed 24" on the east elevation of "Building B" and one 60 square foot secondary wall sign with logo /letters not to exceed 24" to be placed on the east elevation of "Building A" at 17115 IH -35N. The subject property is an approximately three (3) acre tract of land and is currently under construction with an approximately 24,277 square foot retail building. The applicant is proposing to install a secondary wall sign for each of the businesses that will occupy the two corner suites. The proposed sign package includes one 60 square foot secondary wall sign with logo /letters not to exceed 24" on the east elevation of `Building B" and one 60 square foot secondary wall sign with logo /letters not to exceed 24" to be placed on the east elevation of `Building A ". The public hearing notice was published in "The Daily Commercial Recorder" on September 11, 2015 . and in the "Herald" on September 16, 2015. There were seven (7) notices mailed to surrounding property owners on September 11, 2015. At the time of this meeting no responses have been received.

Additionally, under the current UDC this variance would not be needed as the current UDC does not regulate individual tenant space sign area. Staff recommends approval of BOA 2015 -007. Mr. Cox gave the third presentation on BOA201.5 -008 by stating that the Applicant is requesting a variance to Article IX, Section 7.6.D. Maximum Area of Ordinance #96 -5 -28 Unified Development Code as amended and adopted by the Enterprise Business Park PUD, in order to permit a free standing multi- tenant sign with maximum sign area to 267 square feet to accommodate a 33 square foot address identifier on top of the sign at 17115 IH -35N. The subject property is an approximately three (3) acre tract of land and is currently under construction with an approximately 24,277 square foot retail building. The applicant is proposing maximum area of 267 square feet. The sign is ci square feet for an address identifier.

The increase in the maximum area of the sign allows for the addition of a clearly visible address identifier to the top of the sign to aid motorists in finding the retail center. Placing the address identifier at the top of the sign will help to mitigate the visibility obstructions caused by the monument sign and lower grade elevation and provide for clearer more visible address identification of the retail center. 3.

Mr. Tschirhart, the Applicant, stated that he wanted to clarify this property is very unique and there is no egress and ingress off IH35 and the egress and ingress is off Mid Cities Parkway coming off the deceleration lane, so the intent is to bring the address above so that anyone can see the address clearly. Ms. Salas asked if the signage will be illuminated to include the address. Mr. Tschirhart stated yes, but the background will not be illuminated.

Prohibited Materials, in order to permit an electric fence to be installed at 18115 IH -35N. GENERAL INFORMATION: Owner: MAS Development CO LP, Trevor Williams Applicant: Electric Guard Dog LLC, Michael Pate Engineer: Alliance Engineering of Oregon, Jenn Artigo REQUEST: The applicant is requesting a variance to Article 9, Sec.21.9.8, Screening and Fencing to allow an electric fence around the perimeter of the storage yard on the subject property. PUBLIC NOTICE: The public hearing notice was published in "The Daily Commercial Recorder" on October 8, 2015 and in the "Herald" on October 14, 2015. There were five (5) notices mailed to surrounding property owners on October 7, 2015. At the time of this staff report two (2) responses have been received; one (1) in favor of the request from the subject property owner and one (1) neutral to the request. ITEM SUMMARY: The subject property is an approximately 3 acre tract of land containing two buildings totaling approximately 32,000 square feet of floor space and is occupied by a heavy equipment sales, service or rental facility. The applicant is requesting a variance to allow an electric fence around the storage yard which is not permitted by the Unified Development Code (UDC). Pursuant to the UDC Article 9, Section 21.9.8.132b, Fences Nonresidential and Multifamily Areas: Prohibited Materials, above - ground electrical fencing, wire mesh (such as hog wire or chicken wire), screening slats within chain link fences and barbed wire are prohibited except for parcels or lots one (1) acre or greater in size in conjunction with the containment of livestock or farm animals. The applicant installed a ten foot (10') electric fence without a permit around the storage yard at the subject property. The Building Inspections department discovered the fence while conducting scheduled inspections for permitted interior renovation work. Staff meet with the owner and applicant to discuss the fence and code violation. The applicant and property owner expressed a desire to seek a variance for the electric fence. Based on discussion between the Building Office and the property owner the fence has been lowered to eight feet (8') in height, which is the maximum height permitted by the UDC, and de- energized for the duration of the variance process. SUBJECT PROPERTY GENERAL LOCATION ZONING AND LAND USE: The property is located at 18115 IH -35N, approximately 3,250 feet east of the intersection of FM 3009 and IH- 35N. Existing Zoning I Existing Use General Business (GB) I Heavy Equipment Sales, Service or Rental Existing Zoning North Manufacturing Light (N South Right -of -way East General Business (G West General Business (G Existing Use riculturall Undevelol IH -35 CPS Power Station Shoe Store CRITERIA FOR REVIEW: According to UDC, Article 3, Sections 21.3.4.C, In order to make a finding of hardship and grant a variance from the zoning regulations of the UDC, the Board must determine the following: 1. The requested variance does not violate the intent of this UDC or its amendments; UDC Article 9 is intended to enhance property values, maintain aesthetic attractiveness, and promote commercial opportunity in the City, and to support and further the objectives of the City's Comprehensive Land Plan. The variance does not meet the intent of the UDC because the requested electric fence is not being used for the containment of livestock and is expressly prohibited by the UDC. 2. Special conditions of restricted area, topography or physical features exits that are peculiar to the subject parcel of land and are not applicable to other parcels of land in the same zoning district; The purpose of this variance is to acknowledge the special circumstances particular to the subject property. The subject property is not influenced by conditions that are unique to the land or land use. 3. The hardship is in no way the result of the applicant's own actions; or 4. The interpretation of the provisions in this UDC or any amendments thereto would deprive the applicant of rights commonly enjoyed by other properties in the same zoning district that comply with the same provisions. The property has no special circumstances or unique conditions that would result in the need of the variance requested. The variance request conflicts with the provisions of the UDC. Currently properties within the City of Schertz requesting a permit for a new fence are subject to the same electric fence and barbwire regulations. STAFF ANALYSIS STAFF RECOMMENDATION: Staff recommends denial of BOA 2015.009. The request for a variance does not comply with all the criteria for granting a variance as presented above. The applicant desires to erect an electric fence that is not in compliance with what is allowed per Code and does not provide sufficient justification for granting a variance. iN Planning Department Recommendation Approve as submitted Approve with conditions* X I Denial * While the Board can impose conditions; conditions should only be imposed to meet requirements of the UDC.

The EGD Security system is an electrically charged fence powered by 12V marine battery which is charged by a solar panel. An energizer retains the voltage for 1.3 seconds and thus when released it is boosted to 7,000 volts of a totally safe, pulsed electrical charge. Signage posted a minimum of every 50 feet warns of the electric fence. However, the safety of the 'shock' is not advertised and therefore, due to our inherent fear of electricity, most criminals will not take a chance in breeching the perimeter. With this, the EGD proactively deters crime unlike cameras, beams and alarms that react to a crime in commission. This genre of business is a high target for crime due to the fact that their yard contains highly desirable, easily'fenceable' inventory of commercial and residential materials and equipment. Currently, We Rent It has a chain link fence around the perimeter of the property for security and to prevent intruders. This security system has proven ineffective. Many businesses in this industry use 'electric fence' security systems to effectively protect their property where other systems have failed. Essential safety facts regarding Electric Guard Dog fence • Totally independent of city electrical grid — does not plug in to the electrical grid /mains power • Powered by 12V marine battery and solar panel • Totally enclosed inside perimeter fence of 6' minimum height • Only installed to secure outdoor storage lots • Pulsed current, shock delivered every 1.3 seconds for one -ten thousandth of a second • Shortness of duration makes it very safe • Fully tested and approved by: • MetLabs, a Nationally Recognized Testing Lab • Dr. Webster, University of Wisconsin, the leading expert in pulsed electricity • Adheres to International Standard IEC 60336.2.76 of which the United States is a supporting member VARIANCE CRITERIA RESPONSE - WE RENT IT 1. Does the requested variance violate the intent of the Unified Development Code or deprive the applicant of rights commonly enjoyed by other properties in the same zoning district that comply with the same provisions? Response: The requested variance does not violate the current or any future intent of the Unified Development Code. Electric fences are allowed on parcels of greater than one acre; the property requesting the variance is three acres. The interpretation allows for electric fences in conjunction with the containment of livestock or farm animals. The requested variance is for a security fence powered by a 12 -volt DC battery and should not have to be used in conjunction with livestock or animals to keep the criminal class from burglarizing or vandalizing We Rent It — a tax paying business and employer in the City of Schertz. The implied use of animals to ward off the criminal class in conjunction with an electric fence is not an effective form of security. The Electric Guard Dog security fence is proven to be safe and effective as a security deterrent. The remote location of the property and the high value targets secured therein are an open invitation to the criminal class. The only system that actually PREVENTS crime and break -ins is the Electric Guard Dog security system. We Rent It believes the variance is of the utmost importance to the protection of their business and inventory. Response: 2. Do special conditions or restricted area, shape, topography, or physical features exist that are irregular to the subject parcel of land and not applicable to other parcels of land in the same zoning districts? The subject property in question is unique in the following ways: a. High value of inventory— both the equipment and inventory; We Rent It is a supplier of all sizes of construction and residential type machinery and equipment. b. Due to size and nature of items, most must be stored outside and cannot be protected inside a building. These items consist of construction equipment, vehicles, and over -sized construction supplies. c. The subject area is 1,120 linear feet in perimeter; it is not possible for security guards to effectively and constantly monitor the entire lot. d. Two sides of the property are screened by large trees and the eastern side is not able to be seen from the road due to the depth of the lot. Without the security system being sought, it is very easy to obtain access without being seen by patrolling Policemen or a neighborhood watch. e. The business is a reputable business, located in the appropriate zoning and complies with all other ordinances. If approved, the variance authorized will be consistent with the general purpose and intent of the provision from which the variance is sought as the general safety and welfare of the public is maintained, crime is prevented, and the city can police crime other than property break -ins and vandalism. 3. Is the hardship the result of the applicant's own actions or intended for financial interest? Response: This variance is not being sought to relieve illegal acts or self- imposed hardships. The business is a reputable business, located in the appropriate zoning and complies with all other ordinances. If approved, the variance authorized will be consistent with the general purpose and intent of the provision from which the variance is sought as the general safety and welfare of the public is maintained, crime is prevented, and the city can police crime other than property break -ins and vandalism. 4. Would granting this variance be detrimental to the public welfare or injurious to the value of property in the vicinity? Response: The granting of the variance will not be detrimental to the public welfare or injurious to the value of the property in the vicinity of We Rent It. In actuality the installation of the Electric Guard Dog will secure the variance property and increase the security of the surrounding properties and the immediate area by deterring the criminal element. It will be in be in harmony with the general purpose and intent of the approved standards and regulations for the installation of the Electric Guard Dog system. Electric Guard Dog has made a name for ourselves by protecting companies like this one from criminals, we have a certain way of setting up our system fences that is safe to the public and allows for maximum protection of our clients. This is why the client has elected to use our service to protect the business; we have the expertise and experience in creating defense systems that are both safe and effective. Summary of Electric Guard Dog Security System Our Electric Guard Dog security system is a primary low voltage (12V), battery powered (DC), independent of the electrical grid, self - contained system that has a variety of functions to it which make for a 100% medically safe and extremely effective crime deterrent. This system is 10' high and is placed approximately 4 " -12" inside of the existing perimeter fence. It is comprised of 20, 12.5 gauge, galvanized steel wires which are run horizontally to the height of 10'. In our system the first layer of protection (visual deterrent) is our signage (located every 50') which advertises that it is an electric fence. This deters most would -be criminals. The second layer of protection (audible deterrent) of our system is sirens. These sirens sound when an illegal criminal trespasser cuts the wires or places objects on them to insulate them so as to bypass the system. The sirens will automatically shut off after a set amount of time. This audible deterrent usually drives away most of the would -be criminals that are bold enough to proceed in spite of the aforementioned visual deterrent (signage). Included in this second layer of protection is that we monitor our systems. In the event of an alarm, a signal will be sent to our monitoring station, who in turn, contacts our clients to let them know they had an alarm event. Our system does not directly connect to emergency services. The final layer of protection is our voltage. We have a burst of voltage (from the 12V battery) that has a duration of four - ten - thousandths of one second (.00004). If a criminal was bold enough to actually grab or touch our system, they will receive this temporary pulse of voltage which is akin to a slap on the hand from a ruler. This final layer of protection stops the remaining number of criminals that are not deterred by the other layers of protection. With the inclusion of a perimeter barrier fence, electric security fences are as specified in IEC 60335- 2-76, the risk of accidental contact is substantially lowered. Please also take a moment to look at our website, www.electricgLiarddog.com, you will find it helpful as well. 2 Short duration pulses are safer than continuous electric current Figure 2 shows that shock durations longer than 1 second are the most dangerous. Note that as the shock duration is shortened to 0.2 seconds, it requires much more electric current to cause ventricular fibrillation. Electric security fences have taken advantage of this fact by shortening their shock duration to an even shorter duration of about 0.0003 seconds. Therefore, electric security fences are safe and do not lead to ventricular fibrillation due to the short 0.0003 second shock duration. . 5000 Fibrillation threshold 2000 ■ 1000 500 ■\ 200 N x 0 ° 100 E E 50 C C u C 20 w 10L 0.1 ■ 94 kg pony + 12 kg dog 10 kg dog 0 7.5 kg dog . n vg dog g dog 0.2 0.5 10 Shock duration, seconds Figure 2 Thresholds for ventricular fibrillation in animals for 60 -Hz ac current.

It increases to about 800 milliamperes for 0.3 second shock duration. From L. A. Geddes, IEEE Trans. Biomed. Eng., 1973, 20, 465 -468. Electricity near the heart is most dangerous There are four situations where electricity may be applied close to the heart. (1) Figure 3(b) shows when a catheter tube is threaded through a vein into the heart, any accidental current is focused within the heart and a small current can cause ventricular fibrillation. (2) Cardiac pacemakers also pass electric current inside the heart, but the current is kept so small that ventricular fibrillation does not occur. (3) A Taser weapon may rarely shoot a dart between the ribs very close to the heart and apply a 0.0001 second pulse, but this has not been shown to cause ventricular fibrillation. Typically when a person takes an overdose of drugs, he creates a disturbance, police are called, the person refuses to obey, the police Taser him, afterwards he dies of a drug overdose, and the newspapers report, "Man dies after Taser shot." (4) A defibrillator applies a 0.005 second, 40 ampere electric current. This causes massive heart contraction that can change ventricular fibrillation to normal rhythm and save a life. 3 Macroshock Microshock (a) (b) Catheter Figure 3 Effect of entry points on current distribution. (a) Macroshock, externally applied current spreads throughout the body, (b) Microshock, all the current applied through an intracardiac catheter flows through the heart. From F. J. Weibell, "Electrical Safety in the Hospital," Annals of Biomedical Engineering, 1974, 2, 126 -148. When comparing an electric security fence to the above examples, we know that an electric security fence is similar to Figure 3(a). Why do we know that? If a person contacts an electric fence, electric current is concentrated in the limbs and causes a deterrent shock; when it continues to pass through the torso, it spreads out and becomes more diffuse. Therefore as shown in Figure 3(a) and in Figure 2 electric security fences are safe because the deterrent shock spreads out and becomes more diffuse and is of a very short duration. Only power lines cause ventricular fibrillation Table 1 shows that short duration electric pulses, even though applied near the heart do not cause ventricular fibrillation. In contrast, the continuous current from power lines kills 1000 persons per year.

We tested five electric fence energizers to determine their current- versus -time waveforms. We estimated their safety characteristics using the existing IEC standard and propose a new standard. The investigator would discharge the device into a passive resistor —capacitor circuit and measure the resulting maximum voltage. If the maximum voltage does not exceed a limit, the device passes the test. Key words: strength—duration curve, cardiac stimulation, ventricular fibrillation, electric safety, electric fence energizers, standards. 1. Introduction The vast majority of work on electric safety has been done using power line frequencies such as 60 Hz. Thus most standards for electric safety apply to continuous 60 Hz current applied hand to hand. A separate class of electric devices applies electric current as single or a train of short pulses, such as are found in electric fence energizers (EFEs). A standard that specifically applies to EFEs is IEC (2006). To estimate the ventricular fibrillation (VF) risk of EFEs, we use the excitation behavior of excitable cells. Geddes and Baker (1989) presented the cell membrane excitation model (Analytical Strength— Duration Curve model) by a lumped parallel resistance — capacitance (RC) circuit. This model determines the cell excitation thresholds for varying rectangular pulse durations by assigning the strength — duration rheobase currents, chronaxie, and time constants (Geddes and Baker, 1989). Though this model was originally developed based on the experimental results of rectangular pulses, the effectiveness of applying this model for other waveforms has been discussed (IEC 1987, Jones and Geddes 1977). The charge—duration curve, derived from the strength— duration curve, has been shown in sound agreement with various experimental results for irregular waveforms. This permits calculating the VF excitation threshold of EFEs with various nonrectangular waveforms. We present measurements on electric fence energizers and discuss their possibility of inducing VF. 2. Mathematical background and calculation procedures Based on the cell membrane excitation model (Weiss — Lapique model), Geddes and Baker (1989) developed a lumped RC model (analytical strength — duration curve) to describe the membrane excitation behavior. This model has been widely used in various fields in electrophysiology to calculate the excitation threshold. Figure 1 shows the normalized strength — duration curve for current (1), charge (Q) and energy (0. The expression of charge is also known as the charge — duration curve which is important for short duration stimulations. iU 3 1 ca 4 Duration dfr E 300 100 a w 30 10 c u.i 3 1 0.3 a Figure 1. Normalized analytical strength — duration curve for current I, charge Q, and energy U. The x axis shows the normalized duration of dlr. Note that for d « z, Q is constant and the most appropriate variable for estimating cell excitation. (from Geddes and Baker, 1989). The equation for the strength —duration curve is (Geddes and Baker, 1989), t Av= IR(1 -e z), (1) where I is a step current intensity, R is the shunt resistance, Av is the depolarization potential threshold which is about 20 mV for myocardial cells, z is the RC time constant, and t is the time 1 is applied. If we let the stimulation duration go to infinity, the threshold current is defined as the rheobase current (I = b). If we substitute I in equation (1) by b and define the threshold current Id _ Av /R for the stimulation with duration d. Equation (1) becomes, Id = b d (2) 1 -e r We can calculate the threshold charge (Qd) by integrating equation (2) and it becomes, Qd = Idd = bd d 1 -e z (3) For short duration stimulation (d << T ) with duration shorter than 0.1 times the RC time constant, equation (3) can be approximated by equation (4) and it yields equation (5), _d 1- e r (4) T Qd = br (5) Equation (5) suggests that the charge excitation threshold for short duration stimulation is constant and equals the product of the RC time constant r and the rheobase b. Geddes and Bourland (198 5) showed that the charge—duration curve for single rectangular, trapezoidal, half sinusoid and critically damped waveforms had a good agreement for short duration stimulations. Therefore we used the same model to estimate thresholds for stimulation sources where I was not constant, under the same stimulation setting. Cardiac cell excitation has been intensively studied at the 60 Hz power line frequency because most accidental electrocutions occur with 60 Hz current, which has a longer duration relative to the cardiac cell time constant of about 2 ms. However, EFEs operate with pulse durations much shorter than the time constant. 3. Methods Figure 2 shows our experimental test set -up. The EFEs under test consist of Gallagher Group Ltd PowerPlus B600 (EFE1), Gallagher Group Ltd PowerPlus B280 (EFE2), Speedrite HPB (EFE3), Intellishock 20B (EFE4) and Blitzer 8902 (EFE5) EFEs. The short duration electrical pulses from these EFEs are passed though a series of eleven 47 Q (ARCOL D4.29, HS50 47 R F) resistors which measure 518 n, which represents approximately the internal resistance of the human body. It is further connected to two 18 Q (RH 10 207 DALE 10 W 3 %) resistors connected in parallel which measure 9.08 Q. This is used as the sensing resistor across which the oscilloscope measures the output voltage. For these very short pulses it is important to use noninductive resistors because the same current flowing through a resistor that has substantial inductance will measure a larger current than a resistor that is noninductive. To reduce electromagnetic interference, a faraday cage, covered with aluminum foil, was connected to ground. This diverted the electromagnetic interference to ground. The data were collected in EXCEL format from a disk in the Agilent 54621 oscilloscope. The calculations for different parameters presented in Table 1 and the Figures 3 -5 were plotted using MATLAB. 4 S3 Electric Fence 2 pF �— Energizer Taser rRIR2 R3 0000 R11 S4 Oscilloscope S1 g,Og Agilent 200 pF; 54621 - - - - -, i Leak ' Faraday cage S2 Detector Aluminum foil (-------------- - - -- Aluminum foil Figure 2. The EFE is selected by S 1. The current flows through a string of 47 0 resistors R 1 –R i I (total 518 S2) which approximates the internal body resistance of 500 Q. The 9,08 S2 yields a low voltage that is measured by the oscilloscope, 3.1. Determination of current EFEs are used in conjunction with fences wires to form animal control fences and security fences. We tested five EFEs (EFE1 –EFE5) using the experimental set -up in Figure 2 and obtained the output currents shown in Figure 3. 1' 1 0 4 t U 4 • EFE1 _EFE2 2 i� ......

I(t) is the impulse current as a function of time." In 3.117 it defines "output current: r.m.s. value of the output current per impulse calculated over the impulse duration." In 3.118 it defines "standard load: load consisting of a non - inductive resistor of 500 n t 2.5 n and a variable resistor that is adjusted so as to maximize the energy per impulse or output current in the 500 Q resistor, as applicable." In 22.108, "Energizer output characteristics shall be such that — the impulse repetition rate shall not exceed 1 Hz; — the impulse duration of the impulse in the 500 fl component of the standard load shall not exceed 10 ms; — for energy limited energizers the energy /impulse in the 500 Q component of the standard load shall not exceed 5 J; The energy /impulse is the energy measured in the impulse over the impulse duration. — for current limited energizers the output current in the 500 Q component of the standard load shall not exceed for an impulse duration of greater than 0.1 ms, the value specified by the characteristic limit line detailed in Figure 102; an impulse duration of not greater than 0.1 ms, 15 700 mA. The equation of the line relating impulse duration (ms) to output current (mA) for 1 000 mA < output current < 15 700 mA, is given by impulse duration = 41.885 x 103 x (output current) -134." We used these definitions and calculated the total energy, the shortest duration where 95% of the total energy occurs, the rms current for that duration from Figure 3 for the EFEs (EFE1— EFE5). Similarly we calculated the output current using the relationship impulse duration = 41.885 x 103 x (output current) -1.34, provided by the IEC for all the EFEs (EFE1— EFE5). Table 1 lists these under the heading "A. (IEC) ". Table 1 shows that all the EFEs pass the IEC standard. C 5. Proposed new standard IEC (2006) uses the rms current for the shortest duration where 95% of the total energy occurs as the standard to determine if the EFE is safe for use. Geddes and Baker (1989) have shown that for pulses shorter than the cardiac cell time constant of 2 ms, the electric charge is the quantity that excites the cells. We propose a simple experimental set -up shown in Figure 2 to determine the maximum amount of charge that would flow from the EFEs and cause cardiac cell excitation. The cardiac cell is modeled as an RC circuit in Fig. 2 with R = 9.08 S2 and C = 200 gF (GECONOL 975751 117C 200 gF :10% 250 VPK) with the RC time constant of 1.82 ms. For the EFEs (EFE1 and EFE2) the switches S1 and S4 are closed. This allows the 200 gF capacitor to charge rapidly (about 100 [is) and discharge fairly slowly (z= RC = 1.82 ms). Figures 4 and 5 show the voltage vs time waveforms for the different EFEs. The test was not performed for electric fence energizers EFE3 —EFE5. 0 m vi m o � -0.

Discussion Geddes and Baker (1989) have shown that for pulses shorter than the cardiac cell time constant of 2 ms, the electric charge is the quantity that excites cardiac cells. Because the first half wave is the largest, the charge integrated in the first half wave determines cardiac cell excitation. The next half wave discharges the cardiac cell capacitance and does not contribute to cardiac cell excitation. Thus we list integral I(t) = charge Q in Table 1. IEC (2006) integrates F(t), which is roughly equal to I(t). Their Figure 102 roughly follows charge. We propose revising EFE standards for measuring current to determine a safety standard to prevent VF. The new standard would measure cardiac cell excitation. It would not require the complex calculations required to determine "The current which flows during the time period in which 95 percent of the output energy (is delivered)." It would use a simple circuit similar to that in Figure 2 composed of resistors and a capacitor. The investigator would discharge the device into the circuit and measure the maximum voltage. If the maximum voltage does not exceed 5 V (as a conservative estimate), the EFE passes the test. The 500 0 resistor closely approximates the resistance of the body and determines the current that flows through the body.

NOTE 1 This requirement is primarily intended to establish that a desirable level of safety is present or is being maintained in the physical barrier. NOTE 2 When selecting the type of physical barrier, the likely presence of young children should be a factor in considering the size of openings. CC.2 Location of electric security fence The electric fence should be separated from the public access area by means of a physical barrier. Where an electric fence is installed in an elevated position, such as on the inner side of a window or skylight, the physical barrier may be less than 1,5 m high where it covers the whole of the electric fence. If the bottom of the window or skylight is within a distance of 1,5 m from the floor or access level then the physical barrier need only extend up to a height of 1,5 m above the floor or access level. CC.3 Prohibited zone for pulsed conductors Pulsed conductors shall not be installed within the shaded zone shown in Figure CC1. NOTE 1 Where an electric security fence is planned to run close to a site boundary, the relevant government authority should be consulted before installation begins. NOTE 2 Typical electric security fence installations are shown in Figure CC2 and Figure CC3. CC.4 Separation between electric fence and physical barrier Where a physical barrier is installed in compliance with CC.3 at least one dimension in any opening should be not greater than 130 mm and the separation between the electric fence and the physical barrier should be — within the range of 100 mm to 200 mm or greater than 1 000 mm where at least one dimension in each opening in the physical barrier is not greater than 130 mm; — greater than 1 000 mm where any opening in the physical barrier has all dimensions greater than 50 mm; — less than 200 mm or greater than 1 000 mm where the physical barrier does not have any openings. NOTE 1 These restrictions are intended to reduce the possibility of persons making inadvertent contact with the pulsed conductors and to prevent them from becoming wedged between the electric fence and the physical barrier, thereby being exposed to multiple shocks from the energizer. NOTE 2 The separation is the perpendicular distance between the electric fence and the physical barrier.
