Fire Alarm Horns

These horns warn you of a fire with loud beeps. Connect them to your fire detection system, and a signal from your control panel will set them off. They help you comply with NFPA 72 standards for fire alarm systems.

All horns must be mounted to an outlet box: use an existing box in your facility, add an outlet box (sold separately), or choose a horn that includes an outlet box.
