Terminal Identification:
AL1024ULXB2 - Power Supply Board
Terminal Legend Function/Description
L, N Connect 115VAC to these terminals: L to hot, N to neutral (Fig. 4a, pg. 6).
+ DC – Factory connected to ACMS8(CB) (Fig. 4d, pg. 6).
AC Fail
NC, C, NO
Used to notify loss of AC power, e.g.connect to audible device or alarm panel.
Relay normally energized when AC power is present. Contact rating 1A @ 28VDC.
AC or brownout fail is reported within 1 minute of event.
To delay reporting for up to 6 hrs., cut “AC Delay” jumper and reset power to unit
(Fig. 4f, pg. 6).
Bat Fail
NC, C, NO
Used to indicate low battery condition, e.g. connect to alarm panel.
Relay normally energized when DC power is present. Contact rating 1A @ 28VDC.
A removed battery is reported within 1 minute.
Battery reconnection is reported within 1 minute.
Low battery threshold: approximately 21VDC (Fig. 4b, pg. 6).
– BAT + Stand-by battery connections. Maximum charge current 3.6A (Fig. 4c, pg. 6).
