Auxiliary Relay Output Subtotal

(terminals 5, 6, or 7 & 18 – 350mA max.)

4. In Worksheet 4, enter the total calculated subtotals of all listed outputs from Worksheets 1 through 3, then add

to get the combined current.

NOTE: Limit the total power supply standby current to 210mA when a 60-hour standby time is desired.

Determining the Size of the Standby Battery

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 5 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.

5. Using the total calculated from Worksheet 5, calculate the battery capacity required for the

installation.

Worksheet 5: Battery Capacity Calculation Worksheet

Capacity Formula Calculated Value

Standby Capacity Total standby current X 24 or 60 hours X 1.1 contingency factor.

Alarm Capacity Total alarm curr. X 0.1 (6 min)

Total Capacity Add standby and alarm capacities (14AH max.)

6. Use the Battery Selection Table to select the appropriate battery for the installation.
