Auxiliary Power Supplies APS10A

Manufacture: kidde
Product code: APS10A

The Auxiliary Power Supply (APS) is a UL 864 ⭐
✅ 9th 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, security, and access control 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. For access control-only applications, the APS can support batteries totaling up to 65 ampere-hours in an external enclosure. The APS has four Class B (convertible to two Class A) NACs. These can be activated in one or two groups the APS’s unique dual input circuits. The APS has a doormounted 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, UIO modules and/or GSA-RELs. The APS is available in 6.5 or 10 ampere models. Each output circuit is has a capacity of three amperes; total current draw cannot exceed the unit’s rating.

The APS provides additional power and circuits for notification appliances and other 24 Vdc loads. It is listed for indoor dry locations and can easily be installed where needed.

Fault conditions are indicated on the on-board diagnostic LEDs, opening the APS input sense circuit and the trouble relay (if programmed). While this provides indication to the host system, the APS can still be activated upon command. A separate AC Fail contact is available on the APS circuit board, which can be programmed for trouble or AC Fail. There are seven on-board diagnostic LEDs: one for each NAC fault, one for battery fault, one for ground fault, and one for AC power.

The unique dual-input activation circuits of the APS can be activated by any voltage 6 to 45 VDC (filtered-regulated) or 11 to 33 Vdc (full-wave rectified, unfiltered). The first input circuit can be configured to activate 1-4 of the four possible outputs. The second input circuit can be configured to control circuits 3 and 4. When outputs are configured for auxiliary operation, these circuits can be configured to stay on or automatically deactivate 30 seconds after AC power is lost. This feature makes these circuits ideal for door holder applications. The APS also has a separate 200 mA 24 Vdc output that can be used to power internal activation modules.

APS NACs can be configured for a 3-3-3 temporal or continuous output. California temporal rate outputs are also available on certain models. This makes the APS ideal for applications requiring signaling rates that are not available the main system.

In addition to the internally generated signal rates, the APS can also be configured to follow the coded signal rate of the main system NACs. This allows for the seamless expansion of existing NACs. At the top of the steel enclosure, the APS has space and mounting bosses for:

• Up to two SIGA-AA30 or SIGA-AA50 dual-channel audio amplifiers

• One GSA-UIO6 or GSA-UIO6R module motherboard

• Up to two GSA-UIO2R module motherboards

• Up to two GSA-REL releasing modules

• Up to two GSA-MP2L mounting plates modules The above devices are in addition to the three factory-installed Signature module mounting brackets to the right of the APS circuit board.

Cabinet Layout

1 Enclosure: Houses the electronics and two standby batteries

2 Heat sink: Distributes heat away the circuit board

3 Circuit board: Provides connections for all circuits

4 Tamper switch standoffs: 3-TAMP mounting standoffs

5 Jumper JP3: Ground fault enable or disable option

6 AC LED: AC power on

7 Mounting brackets: Option module mounting brackets

8 Jumpers JP1 and JP2: Class A or Class B NAC option

9 DIP switches: Two eight-position DIP switches used for configuration

10 Circuit LEDs: NAC, battery, and ground fault trouble LEDs

11 Batteries: Up to two 12 V 24 Ah batteries fit in the enclosure. For larger batteries, use an external battery cabinet (BC-1 or BC-2).

12 Jumper JP4: Battery charging jumper

13 Option module (GSA-REL, GSA-UIO6/6R/2, GSAMP2L) mounting area

14 Remote LED wiring harness connection

15 Remote LED: Indicates AC power is on

Trouble relay wiring with four AUX circuits

When all four NAC/AUX circuits are configured as AUX circuits and DIP switch SW2-6 is ON, a GSA-CT2 module must be used to monitor the sense 1 trouble contacts and the trouble relay.
