120V AC Wire-In Smoke Alarm
For Basic Use
Part# 21006374 Model i12020A
Description
The Kidde i12020A is an AC powered, ionization
smoke alarm that operates on a 120V power source.
This alarm uses ionization sensing technology. Ionization
sensing alarms may detect invisible fire particles
(associated with flaming fires) sooner than photoelectric
alarms. Photoelectric sensing alarms may detect visible
particles (associated with smoldering fires) sooner than
ionization 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 i12020A includes a quick connect wiring harness
for easy installation. This unit is available in a 6-piece
cut case with tray for easy display. The i12020A is a UL
Listed product with a 10-year limited warranty.
