INSTALLATION AND OPERATION INSTRUCTIONS — FENCE PROTECTION SYSTEMS
Gate Installations
Gates, including sally ports, require the same protection as the fence. There are many types of gates,
but they are generally swinging or sliding. Additionally, gates can be installed as either single or
double gates. Normally, gates are manufactured from the same fabric as the fence so the FPS trans-
ducer cable will provide the same level of protection.
Hinged (swinging) gates that are seldom used, such as gates used for maintenance, can usually be
protected with transducer cable. High usage hinged gates can be protected in the same way but
should probably be assigned their own alarm zone. Sliding gates are best protected using a Telegate.
Gate areas may also be protected using a non fence-mounted sensor such as the MPS-4100 microwave
system.
Swing Gate Installation
Transducer cable installation for a hinged gate is shown in Figure 44. This also applies to personnel
gates. However, with the personnel type of gate, the conduit can be installed over the top of the gate if
space permits. Two weatherproof, electrical junction boxes are mounted on the fence — one on either
side of the gate as close as possible to an upright support post. These are interconnected by a 3/4-inch
diameter conduit which is buried beneath the ground surface. The conduit depth should be a mini-
mum 18 inches. NOTE: Nonsensitive cable must be used in the conduit connecting the two fence
mounted transducer cables. Splice the nonsensitive cable to the transducer cable in each weather-
proof junction box. Use a TSK to accomplish the splice [see Transducer Service Kit (TSK) Installation]
and fill the TSK with Dow Corning 4 electrical insulating compound before sealing.
