Firex Hush Smoke Alarm - P12040 - 21006371

The Kidde Firex P12040 21006371 is a 120 volts powered photoelectric Smoke Detector alarm with 9 volts battery back up. This Firex advanced smoke alarm has the ability to function as a stand-alone unit or in an interconnected system. The Kidde Firex P12040 includes a test button, quick-connect power harness.

This Kidde Firex P12040 alarm uses photoelectric sensing technology. Photoelectric sensing alarms may detect visible particles (associated with smoldering fires) sooner than ionization alarms. Ionization sensing alarms may detect invisible fire particles (associated with flaming fires) sooner that photoelectric alarms.

Kidde strongly recommends that both ionization and photoelectric smoke alarms be installed to help insure maximum detection of the various types of fire that can occur within the home.

The Kidde Firex P12040 includes a 9 volt battery backup to provide continuous protection during a power failure and included a quick connect power harness to make installation simple.
