Appendix A: Secondary Power Calculations
Standby Battery Requirements
The Standby Battery Current obtained in the table below represents the amount of current that must be
supplied by the secondary power source (batteries) to sustain control panel operation for one hour.
Note: The control panel will support the installation of one or two optional modules, including two of the same type of
module. Only one 4XLM can be included in this count.

3. The total standby current must include both the resettable (TB1 - +24VR terminals) and
nonresettable (TB2 - +24VNR terminals) power. Caution must be taken to ensure that current
drawn from these outputs during alarm does not exceed maximum ratings specified.
