120W Occupant Warning System

Occupant Warning System 120W Amplifier

The Ampac Single Zone Occupant Warning System is available as a 120 Watt audio output with optional front panel control. The alert and evacuation signals are compliant to AS1670.1 and NZS4512 including voice messages as standard.

The speaker circuit is protected and monitored for shorts and interruptions. Up to three spur lines (branches) are supported. A monitored strobe output is provided as a standard that supports both xenon and led strobes.

Each audio source (alert/evacuation signals, emergency paging, and secondary analogue audio input) has a dedicated volume control.

Three programmable relays are provided, which default to Emergency Warning Condition, Fault, and Test Mode.

The optional front panel control has an integrated emergency microphone (and can optionally support a handheld microphone)

The Single Zone Occupant Warning System is suitable for use in Ampac’s FireFinder and FireFinder PLUS Fire Alarm Control Panels.
