8. Locate the battery at the bottom of the SMPS box.
9. Connect flying leads (battery connectors) from the SMPS board to the battery
terminals - (+) Red, (-) Black).
Note:
Use only lead acid battery type, rated 12V, 7-21AH (maximum) and safety
approved in accordance with the national standards!
If a continuous AC power outage occurs, the SMPS
automatically disconnects the battery when its backup
battery voltage drops below 10.8VDC. This is done to
prevent "deep discharge" that may damage the battery
The battery may be totally discharged during continuous
AC failure (no deep discharge protection).
Note:
If 2 pins configuration is selected, the battery might be damaged, thus b
may be required.
Note:
The sounder(s) connected to the SMPS operates identically to the main
panel's sounder(s).
For a bell/electronic sounder with a built-in sounder
driver, position jumper on one pin; 12VDC is produced at
the sounder's terminals during burglary/panic alarms.
Slow pulsing voltage is produced during fire alarm.
For a loudspeaker without a built-in sounder driver,
position jumper on both pins. The SMPS produces
continuous oscillating voltage for burglary/panic alarms
and an interrupted oscillating voltage for fire alarm.
