The FireSense stand alone 50W OWS amplifier is ideal for use in existing fire alarm installations that require the addition of an OWS amplifier to meet code requirements.  The stand alone 50W OWS unit has its own 240V power supply, and battery charging capabilities.

An alarm signal from the existing fire alarm panel will trigger the system when in auto mode.  Manual control is achieved by a 4 position rotary switch on the front of the panel which can select manual evacuation or Public address.
