DESCRIPTION When the glass breakage sensor detects the glass is broken (1st time), the sensor will set off an alarm for 20 seconds (pre-alarm). If the glass breakage sensor detects that more glass is broken (2nd time or more), the sensor will set off an alarm for 60 seconds. WIRING DIAGRAM ![]() CAUTION / NOTICE / HINT NOTICE: Inspect the fuses for circuits related to this system before performing the following procedure. PROCEDURE
