Wiring an APS2-6R
Installation
3.3.2 AC Fail/Brownout Detection
The APS2-6R monitors for power loss. In the event there is an AC failure or brownout, the APS2-6R will switch to
battery back-up. The AC Fail Relay (TB4) is monitored by an FMM-1 or equivalent monitor module on the SLC
(Signaling Line Circuit), and in this event, a trouble message will be displayed on the control panel. The monitor
module must be mounted within the same enclosure as the APS2-6R or in a closely coupled
enclosure with wiring
not exceeding 20 feet (6.1 m) in length.
3.3.3 Trouble Supervision Bus
The APS2-6R supervises battery power. If the battery voltage should drop, the APS2-6R will generate and transmit a
trouble to the control panel via trouble supervision cable #71033.
NOTE:
TB4 is for UL 864 9th Edition applications only. See Appendix B for UL 864 8th Edition
applications and wiring.
