Fire Protection Engineers, installers and code enforcers should be aware of the new smoke detection placement requirements in the 2010 edition of NFPA 72®, National Fire Alarm and Signaling Code. The new requirements – applicable to one- and two-family dwellings, guest rooms of hotels, dormitories and dwelling units in apartment buildings – are intended to reduce unwanted alarms from smoke alarms or smoke detectors installed near fixed or stationary cooking appliances. If you are installing fire detection in these types of dwellings, compliance with these new requirements is essential for optimum detection performance and higher immunity to unwanted activations.
