Table 67 Expansion Power Supplies
An expansion power supply mounts in the battery compartment of the cabinet. Batteries
must be relocated to the BB-17 Battery Box. This appendix contains instructions for
mounting and wiring an AVPS-24 and APS-6R as well as instructions for programming
the control panel.
WARNING: Because the AVPS-24/AVPS-24E supplies special purpose power that
is unfiltered & unregulated, only compatible notification appliances listed in the
Device Compatibility Document can be connected to NACs 3 and 4.
J.1.1 AVPS-24 Audio/Visual Power Supply
The AVPS-24 supplies power (unfiltered, unregulated, 3.0 A maximum) to Notification
Appliance Circuits (NACs) and occupies one position on the CHS-4 chassis. A trouble
cable is provided for connection to the control panel. The AVPS-24 mounts in the
bottom of the AFP-200 cabinet. AC power required for the AVPS-24 is 120 VAC,
50/60 Hz, 1.0 A and AC power required for the AVPS-24E is 220/240 VAC, 50/60 Hz,
