+ DC - - - 12VDC or 24VDC @ 2.5 amp continuous power-limited output.
Indicates loss of AC power, e.g. connect to annunciator/alarm panel. Relay normally energized when
AC power is present. Contact rating 1 amp @ 28VDC. AC Fail condition will report approximately
AC Fail
within one (1) minute after loss of AC. To delay report for 6 hours cut jumper J1 on the Power Supply
NC, C, NO
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.
Indicates low battery condition, e.g. connect to alarm panel. Relay normally energized when DC power
Bat Fail is present. Contact rating 1 amp @ 28VDC. Low battery conditions will report approximately 21VDC
NC, C, NO (24VDC output setting) or approximately 10.5VDC (12VDC output setting). Battery presence detec-
tion will report approximately 1 minute after battery remains undetected (missing or removed).
+ BAT - - - Stand-by battery connections. Maximum charge current 0.7 amp.
