The Alpha Communications® AC152 annunciator control unit is used to provide power and control circuits to operate the AlphaLinq™ 100 series visual nurse-call system, but can be used and is backwards compatible with some older systems as well. The AC152 contains the electronic circuitry necessary to detect the presence of routine and emergency calls, and to generate audible and visual control signals. It provides steady or intermittent voltages to operate visual signaling devices. The AC152 supports up to 1 amp of current load from the field devices, and supports interconnection of a secondary power supply to increase the output current load to 3 amps. Protective circuitry has been incorporated to protect routine and emergency call commons from shorts.

The AC152 shall also feature a built-in battery charging circuitry, and a Form 'C' dry contact relay which will activate when system calls are placed.

Each master station requires it's own AC152 for power and control.

The AC152 is U.L. 1069 listed, to the latest standards.
