Using the Wireless Gate Sensor to protect gates
The Wireless Gate Sensor (WGS) operates in conjunction with the FlexZone processor to provide
RF-based wireless security protection for gates. The WGS is comprised of two components. The
gate sensor module (GSM) a high-sensitivity accelerometer, is attached to the protected gate. The
GSM analyzes signals picked up from the fence fabric on the gate and will transmit an alarm when
it detects vibration, motion, or positional changes. A gate sensor receiver (GSR) that is mounted
on the FlexZone processor receives the transmission and passes on the alarm signal to the
FlexZone processor. A rubber whip antenna is mounted on the processor enclosure to facilitate
the WGS communications. Alarm data communications are via the FlexZone processor over the
Silver Network or by contact closures.
Installing sensor cable on gates
Swinging gates usually require the same level of protection as the fence.
•
Install the sensor cable on the side of the fence into which the gate panel opens.
•
If the gate panel opens in the opposite direction, or both directions, leave enough slack in the
sensor cable so that the gate can be fully opened in either direction.
•
Make sure that there is no loose sensor cable when the gate is closed.
•
Run the cable from the fence to the gate at the hinged side of the gate, and then back to the
fence on the same side.
•
Ensure that the cable cannot be caught and pinched when the gate opens and closes.
•
Run the cable once completely around the gate in a diamond pattern, app. 30 cm (1 ft.) from
the edge (respect the minimum bend radius - no sharp corners).
•
Install a bypass cable below ground inside conduit.
•
Continue installing the cable on the remainder of the fence.
Note
See Installing the Wireless Gate Sensor (E7DA0103) for information on
installing and configuring the WGS.
