protection continues. All hardware on the gate must be well secured to prevent any metal on metal
contact while the gate is not in use. Excess sensor cable at a gate location is coiled into a service
loop on the hinged side of the gate.
For a double swinging gate, both gate panels are protected by sensor cable.
Gate protection for periodically bypassed gates (independent zones)
For a gate that will be used while the system is operational, it is recommended that the gate be
made into an independent zone. As an independent zone, the gate can be masked so that it does
not report alarms when it is being used by authorized personnel. The gate zone includes the
sensor cable on the gate, below the gate, and the two adjacent fence panels on each side. The
hinged side of each gate should also have a 10 m service loop. In addition, each side of the gate
can include a 13 m isolation loop to provide a buffer between the adjacent zones. For maximum
isolation between zones, the isolation loops can be installed in buried vaults (see
Attach the isolation loops to the fence with cable ties. The isolation loops must be far enough away
Note
Creating a service loop on the hinged side of all protected gates is
strongly recommended.
