Controlling Guard Zone Alarms
The guard alarm is triggered when a target enters a guard zone which exceeds
the target density threshold. You can set the threshold above which a new
target will trigger an alarm, and can also turn the alarm on or off.
When the alarm is triggered, the unit beeps and a text message is displayed.
➤ To clear the alarm, press any key (on the master or repeater display).
The alarm will sound again after 10 seconds, unless one or more of the
following happens:
• You turn the guard zone off
• You adjust the guard zone size/shape to reduce the number of targets in the
zone
• You turn the alarm off
• You decrease the alarm sensitivity
• The target leaves the guard zone
➤ To change the alarm sensitivity setting:
1. Press MULTI to display the sliders.
2. Press the ALARM soft key to highlight the Alarm slider.
3. If required, press the soft key again to toggle the setting between OFF and
ON. You can only move the slider if the control is set to ON.
4. Use the trackpad to increase or decrease the alarm slider setting. You can
press and hold the trackpad to change the value more rapidly.
5. The higher the setting, the more sensitive the alarm, and the smaller the tar-
get density required to set it off.
6. Press ENTER to clear the slider display.
