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.
