SKU: 55000-852 Category: Brand:


The XP95 Sounder Control Unit with Isolator is used to control the operation of a zone of externally powered sounders and to report their status to Apollo compatible control equipment. This Sounder Circuit Controller can allow units to be operated continuously, or to be pulsed, 1 Second on, 1 Second off. The controller can also be synchronised with loop sounders. 

Key Features

The Sounder Control Unit with Isolator allows sounders to be operated continuously or be pulsed, 1 second on, 1 second off. Sounders may be operated individually or in groups and, whichever address mode has been applied, may be synchronised when in pulsed operation.

An opto-coupled input is provided to monitor the state of the external power supply.

The Sounder Control Unit with Isolator is fitted with a bi-directional short-circuit isolator and will be unaffected by loop short-circuits on either loop input or output.
