5. Connect battery to the terminals marked [+ BAT -] (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 are desired, they must be lead acid or gel type.
6. Connect appropriate signaling notification devices to AC Fail supervisory relay outputs marked [NC, NO, C].
Note: To meet UL requirements, AC Supervisory outputs must be connected to the zone of Alarm Control Panel or
to visual AC trouble indicator.
7. For Access Control Device & Fire Alarm Interface connections refer to desired Application Diagrams (pg. 4)
and (Terminal Identification Chart, pg. 3).
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
(see Power Supply Output Specifications Chart).
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 400mA.
Note: Expected battery life is 5 years; however, it is recommended changing batteries in 4 years or less if needed.
