Auxiliary Power Supplies

4.6(7 評價)

Overview:

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), as well as 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. These can be activated in one or two groups from the APS’s unique dual-input circuits. The APS has a door-mounted AC power indicator LED.

The APS also has room for and can power a number of different modules. These can be Signature AA-30 or AA-50 dual-channel audio amplifiers, SIGA-UIO modules and/or SIGA-RELs. An MN-BRKT3F can also be installed. This bracket can accommodate an MN-FNS4C2F3 or MN-FNS8C2F3 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; total current draw cannot exceed the unit’s rating. Features:

Allows for reliable filtered and regulated power to be installed where needed
Cost-effective system expansion
Provides for Genesis and Enhanced Integrity notification appliance synchronization
Supports coded output operation
Self-restoring overcurrent protection
Multiple signal rates
Can be cascaded or controlled independently
Easy field configuration
On-board diagnostic LEDs identify wiring or internal faults
Standard EDWARDS keyed lockable steel cabinet with removable door
110 and 230 Vac models available
Accommodates 18 to 12 AWG wire size
Optional tamper switch
Dual-battery charging rates
Optional earthquake hardening: OSHPD seismic pre-approval for component Importance Factor 1.5

The APS meets current UL requirements and is listed under the following standards:

Engineering Specification:
Supply, where needed, EDWARDS APS Series Auxiliary Power Supplies (APS) that are interconnected to and supervised by the main system. The APS shall function as a stand-alone auxiliary power supply with its own fully-supervised battery complement. The APS battery complement shall be sized to match the requirements of the main system. The APS shall be capable of supervising and charging batteries having the capacity of 65 ampere-hours for Mass Notification/Emergency Communication (MNEC), life safety and security applications.
<>The APS shall provide a minimum of four independent, fully supervised Class B circuits that can be field-configurable for notification appliance circuits or auxiliary 24 Vdc power circuits. APS NACs shall be convertible to a minimum of two Class A NACs. Each APS output circuit shall be rated at 3 amperes at 24 Vdc. Each output circuit shall be provided with automatically restoring overcurrent protection. The APS shall be operable from the main system NAC and/or EDWARDS Signature Series control modules. APS NACs shall be configurable for continuous, 3-3-3 temporal rate. Fault conditions on the APS shall not impede operation of main system NAC. The APS shall be provided with ground fault detection circuitry and a separate AC fail relay.
