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. The gate zone includes the sensor cable on the gate, below the
gate, and the two adjacent fence panels (one panel on each side). In addition, each side of the
gate should have a 13 m isolation loop to provide a buffer between the adjacent zones. The hinged
side of each gate should also have a 10 m service loop. The isolation loops should be far enough
away from the gate to prevent the transmission of vibrations into the adjacent zones when the gate
is in use. The SMS software should be configured to ignore alarms from the gate zone when the
gate is in use (zone accessed/bypassed).
Note
FiberPatrol recommends creating a service loop on the hinged side of
all protected gates.
