Connecting the Backup Battery
In the event of an AC power loss, the control panel is supported by a backup, rechargeable
Sealed Lead Acid battery. The range of battery sizes recommended are: 12VDC; 4AH-
17.2AH. See "Calculating the Battery Size Needed" earlier in this section. The battery is
installed in the control cabinet.
Making the Battery Connections
1. Use the battery standby formula (above) to select the appropriate battery for the
installation.
Do not connect the battery until all devices have been wired to the control.
2. Attach the red and black battery wires from the control board to the battery as follows:
•
Red to the positive (+) terminal on the battery.
•
Black to the negative (–) terminal on the battery.

Use a 4AH battery or larger for UL installations. Calculate the actual battery size needed by
referring to the proper paragraph in this section.
Battery Tests
The standby battery is automatically tested every 4 hours, beginning 4 hours after exiting
Programming mode or after a system reset. In addition, entry into the Test mode causes a
battery test to be initiated.
If the battery cannot sustain a load, a LOW BATTERY message is displayed and, if so
programmed, is reported to the central station. In addition, the connection to the battery is
checked every 3 minutes (a CSFM requirement). If there is no battery detected, or a low-
battery condition is detected, a LOW BATTERY message is displayed and a report is sent to
the central station.
