To reset an anomaly, remove its cause first, wait 10 seconds and then give an input to terminal no.3 or no.5.
Installation:
when supplied, the sounder is in stand-by condition until input 3 “sounder control” is tur-
ned out and turned on again. This prevents the sounder from sounding during installation.
Attention:
if battery is out of charge (voltage is lower than 10.5V), in case of alarm, the sounder operates
for 3 seconds only, in order to avoid a deeper discharge.
Usual sounder working: the microprocessor continuously tests the battery voltage. If the battery is out of
charge (voltage is lower than 10.5V), the sounder sounds for 3 seconds only. Vice versa, the flash keeps
on working as usual. If voltage decreases under 9.5V, the sounder produces no acoustic alarm and the
flash does not work to avoid a deeper battery discharge.
Maintenance:
During battery replacement, it is advisable to disconnect the recharge too (Terminal no.2). By proceeding
so, the complete sounder test will start immediately.
After 30 seconds from power supply reception, the microcontroller performs the battery test. Such test is
then repeated every 2 hours. If an alarm occurs during the first 30 seconds, the battery anomaly notice
stays until the following test (which will be performed after 2 hours). If the flashing light activates when
an anomaly is detected, it will flash fast.
If battery voltage decreases under 10.5V, the LED flashes fast when the sounder is in alarm status or the
Alarm System ON/OFF mode is enabled.
