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 @ 13.7 or 24VDC @ 27.4) 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 0.7 amp.
Note: Expected battery life is 5 years; however, it is recommended changing batteries in 4 years or less if needed.

LED Diagnostics:

Red (DC1)

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. Short circuit or thermal overload condition.

OFF

OFF

Loss of AC. Discharged or no stand-by battery. No DC output.

Terminal Identification:

Terminal Legend

Function/Description

L, G, N

Connect 115VAC/230VAC to these terminals: L to Hot, N to Neutral, G to ground.

– DC1 +

DC1 - 12VDC or 24VDC @ 3 amp and DC2 - 12VDC @ 1 amp
Note: If DC2 is not used, DC1 rating is 12VDC or 24VDC rated @ 4 amp max.

– DC2 +

12VDC @ 1 amp.

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 1 amp @ 115VAC / 28VDC

Low Battery

NC, C, NO

Indicates low battery condition, e.g. connect to alarm panel. Relay normally energized when

DC power is present. Contact rating 1 amp @ 115VAC / 28VDC.

Low battery threshold: 12VDC output threshold set @ approximately 10.5VDC,

24VDC output threshold set @ approximately 21VDC.

– BAT +

Stand-by battery connections. Maximum charge rate 0.7 amp.
