Specications
The Model ACBC-120
is a dual purpose alarm controller/battery charging
unit. When there is a loss of 120VAC power,
the ACBC-120’s primary function as an alarm
controller activates. When this power loss occurs,
input power is switched to a 12VDC, lead-acid,
rechargeable backup battery and a 12VDC alarm
consisting of a strobe light and/or a horn is
activated. The horn follows a 2 second on/2 second
off pattern with a “horn silence” option to turn
the sound off. An LED indicator on the unit also
signals that the device has entered the alarm mode.
When 120VAC input is present the alarm circuit
can be tested and the unit’s secondary function as a
12VDC backup battery charger is activated. In fast
charge mode, the unit has the capability to source
up to 100mA of charging current. However, the
device normally charges at a current of 14mA in maintenance mode. The alarm circuit can be tested
by pressing the “test” button located on the front of the unit or by activating an external switch via
the “alarm contact” pin.
The device has the ability to signal low battery voltage if the voltage drops below 10.5VDC. The
device can also detect if no battery is present or if the battery is connected backwards. In either of
these cases, the ACBC-120 will signal a battery error and will not attempt to charge.
