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 both at battery terminal and at
the board terminals marked [+ BAT -] to insure there is no break in
the battery connection wires.

Note: Maximum charging current under discharge is 3.6 amp.
Note: Expected battery life is 5 years, however it is recommended

changing batteries in 4 years or less if needed.

LED Diagnostics:

Red (DC) Green (AC) Power Supply Status

ON ON Normal operating condition.
ON OFF Loss of AC, Stand-by battery supplying power.
OFF ON No DC output.
OFF OFF Loss of AC. Discharged or no stand-by battery. No DC output.

L, G, N Connect 115 VAC to these terminals:

L to hot, N to neutral, G to ground.

- DC + 24VDC @ 8 amp continuous, 10 amp in alarm non-power limited output.

AC FAIL Used to notify loss of AC power, e.g.connect to audible device or alarm
N.O., C, N.C. panel. Relay normally energized when AC power is present.

Contact rating 1 amp @ 28VDC.
AC or brownout fail is reported within 1 minute of event. To delay reporting of up to
6 hrs., cut “AC delay” jumper and reset power to unit.

BAT FAIL Used to indicate low battery condition, e.g. connect to alarm panel.
N.O., C, N.C. Relay normally energized when DC power is present.

Contact rating 1 amp @ 28VDC.
A removed battery is reported within 1 minute. Battery reconnection is reported
within 1 minute.
Low battery threshold: @ approximately 21VDC.

+ BAT - Stand-by battery connections. Maximum charge current 3.6 amp.
