Section 3 – Installing the Control
3-31
The total control standby load must be limited to 1A for 24-hour standby time using a 12V, 34.4AH battery
connected to the control.
Determining the Size of the Standby Battery
For burglary installations requiring 4-hour standby time followed by 15-minutes alarm time, use a 12AH battery to
support all loads up to and including the maximum system load (e.g., 1A standby/2.7A alarm total control panel load).
For fire installations requiring 24-hour, use the worksheet below to calculate the required battery capacity.
DO NOT use Gates batteries (sealed lead-acid type). These batteries require a different charging voltage than is
supplied by the panel.
Use Worksheet 7 to determine the required backup battery capacity and use The Battery Selection Table to determine
the battery model number. A dual battery harness is supplied that allows two batteries to be wired in parallel for
increased capacity.
7. Using the total calculated from Worksheet 6, calculate the battery capacity required for the installation.
