Table A-1: Standby Battery Requirements
The Standby Battery Current figure obtained in Table A - 1 represents the amount of current that must
be supplied by the secondary power source (batteries) to sustain control panel operation for one hour.
Basic Control Panel
80 mA
Control panel with AC power off, System Trouble LED and audible trouble sounder on.
If using a 4XZM Zone Relay Module
[ ] X 8 mA =
If using a 4XTM Transmitter Module, add 11 mA
If using the Reverse Polarity Alarm output, add 5 mA
If using the Reverse Polarity Trouble output, add 5 mA
If using a 4XLM/RZA-4X Driver/Annunciator combination:
