BACKUP BATTERY:
The Red (+) and Black (-) flying leads must be connected to a 12VDC 4-7AH battery to serve as backup
power in the event of AC loss.
A battery test occurs approximately every 4.5 minutes. Low-battery conditions occur at nominal
11VDC. The keypad AC/LB LED and buzzer will pulse slowly when a low-battery condition is detected.
The system reports this condition to the central station if programmed to do so. Battery restoration
occurs within 4.5 minutes, at the NEXT battery test. The buzzer may be silenced by entry of any valid
user code.
NOTE: For UL installations, use two 4AH batteries connected in parallel.

**If devices such as PIRs, smoke detectors, etc. are used, refer to the specifications for that particular
device's current draw. If the total current draw exceeds 500mA, then use an additional power supply.
NOTE: For UL installations, do not exceed 180mA.
NFPA, UL, and the California State Fire Marshal require the backup battery to provide power
for 24 hours. The maximum auxiliary power will vary by the ampere/hour rating of the battery
used:
5AH = 95mA; 7AH = 180mA; 8AH = 210mA.
