4. Measure output voltage before connecting
devices. This helps avoid potential damage.
5. Connect one (1) 12VDC battery to
terminals marked [+ BAT - -]
(Fig. 1, pg. 2) for 12VDC operation.
Use two (2) 12VDC batteries connected in
series for 24VDC operation,
(Battery leads included).
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.
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 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 batteries is desired they must be lead acid or gel type. Connect battery to the terminals
marked [+ BAT -- ] (Fig. 1) (battery leads included). Use two (2) 12VDC batteries connected in series
for 24VDC operation.
8. For Access Control Device & Fire Alarm Interface connections refer to desired Application Diagrams (pg. 4)
and Terminal Identification Chart (pg. 3).
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
(refer to Power Supply Output Specifications Chart).
Battery Test: Under normal load conditions check that the battery is fully charged, check specified voltage both at
battery terminal and at the board terminals marked [- BAT +] to insure there is no break in the battery connection wires.
Note: Maximum charging current under discharges is 0.40 amp.
Note: Expected battery life is 5 years, however it is recommended changing batteries in 4 years or less if needed.
