6.6 PFC-7500 Series Power Requirements
During AC power failure, the PFC-7500 Series panels, and all auxiliary devices connected to the panels, draw their
power from the battery. All devices must be taken into consideration when calculating the battery standby capacity.
Below is a list of the power requirements of the PFC-7500 Series panels. Add the additional current draw of Potter
keypads, smoke detectors, and any other auxiliary devices used in the system for the total current required.
