What type of smoke detectors are there?

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.
