ACBC-120 SERIES

Alarm Controller and Battery Charger for

pump control panels

Description

The ACBC-120 Series 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.
