Low Battery; Wall Tamper Tab; Maintenance - Bosch ICP-EZM2 System Reference Manual

Figure 8.1: Testing behind curtains
The detector switches from test mode to normal mode after at least 1 minute of silence from
the hand-held tester.
Notice!
When the detector is in normal mode, the LED is off unless a loud sound is detected.
Room acoustics can artificially extend the range of a glassbreak sensor. The specified sensor
range is for worst-case conditions. While the sensor likely functions at a greater range, it might
not detect a low volume breaking sound, or room acoustics might change at a later point in
time. Do not exceed the rated range of the sensor, regardless of what the tester shows.
Test the sensor operability
When the detector is in normal mode, the LED is off unless a loud sound is detected.
Therefore, to ensure the glassbreak has power and that the microphone is functional, perform
a simple hand clap test.
To perform a hand clap test, simply clap your hard loudly under the sensor. Verify the LED
blinks twice.
8.7.3

Low battery

When a low battery state is detected, the detector measures the battery, and sends a report
to the receiver/control panel.
8.7.4

Wall Tamper Tab

Use the wall tamper tab to activate an alarm when the glass break has been removed from the
wall.
8.7.5

Maintenance

Clean the cover with a damp (water) cloth as needed to keep it free of dust and dirt. Always
test the sensor after cleaning it.
