The Littelfuse 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 Littelfuse
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
Littelfuse ACBC-120 will signal a battery error and will not attempt to charge. The Littelfuse ACBC-120 requires a Rectangular 12 pin socket. for surface mounting. Littelfuse part number is SD12-PC.
Features & Benefits
Controls 12VDC alarm circuit >> Activates strobe and/or horn when power loss occurs
Selectable fast charge mode >> Unit sources higher charging current up to 100mA (normal mode is 14mA)
Trip delay timer >> Prevents nuisance tripping
Battery fault detection and reverse polarity protection >> Signals if battery voltage drops below 10.5VDC and can detect if no battery is present or if the battery is connected backwards
LED Indication >> Visual indication of unit status or trip
Test button >> Preventative maintenance check of the alarm circuit by pressing the test button on the unit or externally through alarm contact connection
