Gate bypass cable
To bypass a gate in a FlexZone zone, run the sensor cable from one side of the gate to the other,
underground inside conduit. Secure the bypass cable at both sides of the gate. The bypass cable
is then specified as non-detecting during the calibration process (cable set as non-detecting does
not report alarms). The gate can be protected with another technology, such as a microwave
sensor. Optionally, create a 3 m (10 ft.) isolation loop at each end of the software bypassed cable.
Bypass cable installation instructions
1. Install the sensor cable on the fence leading up to the gate in the usual manner.
2. Cut a piece of PVC conduit to the required length, and bury the conduit at a depth of at least
45 cm (18 in.). Consult the local building code for conduit burial depth recommendations.
3. Pull the sensor cable through the buried conduit.
4. Seal the ends of the conduit.
5. Use cable ties to tightly secure any exposed bypass cable to the fence fabric.
6. Continue installing the sensor cable on the fence beyond the gate.
Installing sensor cable on swinging gates
1. Run sensor cable to the hinged side of the gate.
2. Make a service loop that reaches the gate without binding the cable when the gate is fully
opened in either direction.
3. Run the sensor cable around the perimeter of the gate panel in a diamond pattern, app. 30 cm
(12 in.) in from the edges.
(For a double panel swinging gate install the sensor cable on both gate panels.)
4. Pull the sensor cable through the buried conduit.
5. Seal the ends of the conduit.
6. Use cable ties to tightly secure any exposed bypass cable to the fence fabric.
7. Continue installing the sensor cable on the fence beyond the gate. (For a double panel gate,
install the sensor cable on the second gate panel before continuing the cable run.)
Note Use minimum 2.5 cm (1 in.) diameter conduit and 90º sweeps (not
elbows).
