Terminal Identification:
Power Supply Board
Terminal Legend Function/Description
L, G, N
Connect 115VAC 60Hz. to these terminals: L to Hot, N to Neutral. Do not use the [G] terminal.
+ DC –
12VDC or 24VDC @ 2.5A continuous power-limited output.
AC Fail
NC, C, NO
Indicates loss of AC power, e.g. connect to annunciator/alarm panel. Relay normally ener-
gized when AC power is present. Contact rating 1A @ 28VDC. AC Fail condition will report
approximately within one (1) minute after loss of AC. To delay report for 6 hours cut jumper
J1 on the Power Supply Board (AC trouble output delay option). If this mode is selected, the
Power Supply Board must be reset by removing all power to it for 30 seconds.
Bat Fail
NC, C, NO
Indicates low battery condition, e.g. connect to alarm panel. Relay normally energized
when DC power is present. Contact rating 1A @ 28VDC. Low battery conditions will report
approximately 21VDC (24VDC output setting) or approximately 10.5VDC (12VDC output
setting). Battery presence detection will report approximately 1 minute after battery remains
undetected (missing or removed).
+ BAT –
Stand-by battery connections. Maximum charge current 0.7A.
