RESERVE POWER
General Description
This feature provides backup power from a 24V battery source in the event of a commercial power failure.
Station Application
Not applicable.
Operating Procedure
No manual operation is required.
Service Conditions
1. Batteries should be installed inside the PIM or separately from the system.
2. Sealed lead acid (or maintenance free) batteries must be locally provided.
3. No interruption of system operation should occur during switchover from commercial to battery power.
However, when the system senses the supplied voltage from the batteries has dropped to 20-21 volts, the
system will automatically shut down to prevent excessive discharge of the Reserve Power batteries.
4. Duration of battery operation is a direct function of the capacity of the batteries installed, and the quantity
and types of cards installed.
5. The Reserve Power requirements are dependent on the configuration of each individual system.
