Description
Install Confidence
The Kidde i12040 is an AC/DC powered, ionization
smoke alarm that operates on a 120V power source
with 9V battery backup.
Easy Installation
• Front battery pull tab allows battery activation without
removing alarm from mounting bracket.
• Large mounting base makes mounting easier, protects
surface paint from dirt and covers imperfections.
• Pre-stripped wiring harness with easy off cap does not
require stripper tool. Tinned strands increase
conductivity and wire nut grip.
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.
Fewer Callbacks
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.
• One button design for easy operation and less
confusion. Operates Smart Hush™ and alarm test
• Battery run down protection will shut down alarm
memory when AC power is not present, reducing
low battery chirp.
This smoke alarm is available in a 6-piece cut case with
tray for easy display as well as a 6-piece bulk pack for
contractors and property owners. This unit is a UL Listed
product with a 10-year limited warranty.
• Dust cover protects sensor from contaminates during
construction reducing nuisance alarms
