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 you perform one or more
of the following actions:
• Turn the guard zone off
• Adjust the guard zone size/shape to reduce the number of targets in the
zone
• Turn the alarm off
• Decrease the alarm sensitivity
➤
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.

get density required to set it off.
