Replace Old Smoke Detectors
Smoke alarm sensors wear down over time, limiting their ability to function. Smoke alarms should be replaced every 10 years.
Hard-Wired Vs. Battery Operated Smoke Detectors
When more than one smoke alarm is required to be installed within an individual dwelling unit the alarm devices shall be interconnected in such a manner that the actuation of one alarm will activate all of the alarms in the individual unit. This does not pertain to legally existing dwellings unless work requiring a structural permit is taking place.
Smoke Detectors Near Kitchens
There are two main types of smoke detectors, Ionization, and Photoelectric. Photoelectric smoke detectors are best at detecting the large particles typical of smoky, smoldering fires but poor at detecting fast, flaming fires. Photoelectric units are less prone to false alarms from burnt food, so they may be a better fit in kitchen areas.
Wall Or Ceiling Location?
Follow manufacturer’s location guidelines.
Smoke detectors should be installed only according to the manufacturer’s instructions. Be sure to follow the guidelines as to height and proximity to corners.
