Terminal Identification:
Terminal
Legend
Function/Description
L, G, N
Connect 115VAC 60 Hz. to these terminals: L to hot, N to Neutral. Do not use the [G] terminal.
+ DC ---
12VDC or 24VDC @ 6 amp continuous non power-limited output.
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 @ 28VDC. AC or brownout fail is reported within 1
minute of the event. To delay reporting for up to 6 hrs., cut “AC delay” jumper and reset power to unit.
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 1 amp @ 28VDC. Low battery conditions will report approximately 21VDC
(24VDC output setting) or approximately 10.5VDC (12VDC output setting).
Battery presence detection will report approximately 1 minute after battery remains undetected
(missing or removed).
+ BAT ---
Stand-by battery connections. Maximum charge current 0.7 amp.
Use 14 AWG or larger for all power connections.
Wiring:
Note:
Take care to keep power-limited circuits separate from non power-limited wiring (115VAC, 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
(Power Supply Voltage Output Specifications Chart, pg. 3).
Battery Test:
Under normal load conditions check that the battery is fully charged, check specified voltage 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.
