The Auxiliary Power Supply (APS) is a UL 864, 10th Edition listed power supply. It is a 24 Vdc filtered-regulated and supervised unit that can easily be configured. To provide additional notification appliance circuits (NACs). Or auxiliary power for Mass Notification/ Emergency Communication (MNEC) and life safety applications.
The APS contains the circuitry to monitor and charge internal or external batteries. Its steel enclosure has room for up to two 24-ampere-hour batteries. The APS has four Class B (convertible to two Class A) NACs. The APS’s unique dual input circuits can activate these in one or two groups. The APS has a door-mounted AC power indicator LED.
The APS has room for and can power several different modules. Including Signature AA-30 or AA-50 dual-channel audio amplifiers, SIGA-UIO modules, and/or SIGA-RELs. An MNBKRT3 can b e installed. This bracket can accommodate an MN-NETSW1 Ethernet network switch, an MN-FVPN VoIP module, and an MN-COM1S Communications module.
The APS is available in 6.5 or 10-ampere models. Each output circuit has a capacity of three amperes; the total current draw cannot exceed the unit’s rating.
