The Kidde ACHS is a single-channel audio selector module that delivers supervised preamp-level output for fire alarm audio and voice evacuation systems. It connects to Kidde intelligent fire alarm control panels via serial interface and supports up to three units per node, scaling audio distribution across a facility without additional controller hardware.
Built for the fire alarm installer
The ACHS integrates into Kidde's intelligent fire alarm platform through serial port connectivity, with dedicated ports for both input and programming. Onboard diagnostic LEDs (Power, Line, Busy, Run, Data, Load, Trouble) give instant visual status during commissioning and troubleshooting, cutting diagnostic time on the job. The rack-mountable chassis fits standard fire alarm system enclosures.
