Product Overview

The Ampac Single Zone Occupant Warning System is available with a 25 Watt and 50 Watt audio output with an 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 standard which 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 System, Fault, and Test Mode.

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