8. To delay AC reporting for 2 hrs., set SW2 to appropriate DIP switch position [AC Delay] (Fig. 1c, pg. 3).
9. To enable or disable Low Output Power Shutdown set SW2 to appropriate DIP switch position [Shutdown]
(Fig. 1c, pg. 3).
10. A short or NO or NC input triggers FACP [Trigger EOL Shutdown] (Fig. 1d, pg. 3).
11. Place a jumper for non-latching FACP. A momentary short on these terminals resets FACP latching
[Trigger EOL Shutdown] (Fig. 1e, pg. 3).
Wiring:
Use 18 AWG or larger for all low voltage power connections.
Note: Take care to keep power-limited circuits separate from non power-limited wiring (120VAC, Battery).
Maintenance:
Unit should be tested at least once a year for the proper operation as follows:
Output Voltage Test: Under normal load conditions, the DC output voltage should be checked for proper
voltage level.
Battery Test: Under normal load conditions check that the battery is fully charged, check specified voltage
(12VDC @ 13.2 or 24VDC @ 26.4) both at the battery terminal and at the board terminals marked [– BAT +]
to ensure that there is no break in the battery connection wires.
Note: Maximum charging current under discharges is 1.54A.
Note: Expected battery life is 5 years, however it is recommended changing batteries in 4 years or less if needed.

Function/Description
L, G, N
Connect 120VAC 60Hz to these terminals: L to hot, N to neutral, G to ground
(non power-limited) (Fig. 1a, pg. 3).
– DC +
12VDC or 24VDC @ 2A continuous output (power-limited output) (Fig. 1h, pg. 3).
Trigger EOL
Supervised
Fire Alarm Interface trigger input from a short or FACP. Trigger inputs can be normally open,
normally closed from an FACP output circuit (power-limited input) (Fig. 1d, pg. 3).
NO, GND
RESET
FACP interface latching or non-latching (power-limited) (Fig. 1c, pg. 3).
+ AUX –
Auxiliary power-limited output rated @ 1A (unswitched) (power-limited output) (Fig. 1f, pg. 3).
AC Fail
NC, C, NO
Indicates loss of AC power, e.g. connect to audible device or alarm panel. Relay normally
energized when AC power is present. Contact rating 1A @ 30VDC (power-limited)
(Fig. 1b, pg. 3).
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 @ 30VDC. A removed battery is reported within 5
minutes. Battery reconnection is reported within 1 minute (power-limited) (Fig. 1b, pg. 3).
– BAT +
Stand-by battery connections. Maximum charge current 1.54A (non power-limited) (Fig. 1g, pg. 3).
