120V AC Photoelectric Smoke Alarm
Part# 21006371 Model PE120
Description
The Kidde PE120 is a 120VAC powered photoelectric
smoke alarm with 9V battery back up. This advanced
smoke alarm has the ability to function as a stand-alone
unit or in an interconnected system. The Kidde PE120
includes a test button, quick-connect power harness and
offers a 10-year limited warranty.
This 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 pho-
toelectric 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 PE120 120VAC includes a 9V battery backup,
providing continuous protection even during a power
failure and includes a quick connect power harness mak-
ing installation simple.
