Jumper Description
BAT
Battery discharge protection
Protection
ON
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 ʺdeep discharge”
that may damage the battery .
Protection
OFF
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,
may be required.
Bell/LS
Used to determine the SMPS mode of operation in accordance with
the sounder device connected to the BELL/LS terminals.
Note:
The sounder(s) connected to the SMPS operates identically to the
panel’s sounder(s).
Bell For a bell/electronic siren with a built‐in siren 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.
LS
(Speaker) For a loudspeaker without a built‐in siren driver, position
jumper on both pins. The SMPS produces continuous
oscillating voltage for burglary/panic alarms and an
interrupted oscillating voltage for fire alarm.
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!
