There are two basic types of smoke detectors: Ionization and photo-electric. Both are effective at detecting fire, yet each has a unique detecting system. Each type of detector comes as AC-operated smoke detectors or battery-powered smoke detectors. Some AC detectors come with a battery back-up system. Photoelectric detectors should not be installed within 10 feet of a cooking appliance.
Since there are many variables in the mounting of smoke detectors please call the Kalispell Building Department for additional information.
