Edwards Releases New Line of Low Frequency Audible Fire Alarm Notification Appliances

All appliances use NFPA 72-mandated frequency of 520Hz.

Edwards released a full line of low frequency audible alarm notification appliances on Tuesday at ASIS that comply with NFPA 72, the National Fire Alarm and Signaling Code.

The code mandates that alarms in sleeping areas such as dormitories, multi-family dwellings, hotels and other properties use a low frequency (520Hz) tone to alert occupants of a fire or carbon monoxide emergency.
