4. Connect battery to the terminals marked [+ BAT -] on the unit (battery leads included). Use two (2) 12VDC
batteries connected in series for 24VDC operation.
Note: For Access Control applications batteries are optional. When batteries are not used, a loss of AC will result
in the loss of output voltage. When the use of stand-by batteries is desired, they must be lead acid or gel type.
5. Connect appropriate signaling notification devices to AC Fail and Low Bat supervisory relay outputs.
Note: To meet UL requirements, AC Supervisory outputs must be connected to the zone of Alarm Control Panel or
to visual AC trouble indicator.
6. For Access Control Device connections refer to Terminal Identification Chart.
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 Output Specifications Chart).
Battery Test: Under normal load conditions check that the battery is fully charged, check specified voltage both at the bat-
tery 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 discharge is 400mA.
Note: Expected battery life is 5 years; however, it is recommended changing batteries in 4 years or less if needed.

No DC output.
Loss of AC. Discharged or missing stand-by battery. No DC output.
Terminal Identification:
Function/Description
Low voltage AC input.
Continuous positive (+) DC power output voltage. Common negative (-) output (ground).
Stand-by battery connections.
Used to notify loss of AC e.g connect audible device or alarm panel. Relay is normally energized
when AC power is present. Contact rating 1A @ 28VDC.
Used to notify low battery condition e.g connect audible device or alarm panel. Relay is normally
energized. Contact rating 1A @ 28VDC.
