Kidde i12040 - Smoke Alarm

Single Sensor - Detects Flaming Fires - 120V Wire-in with Battery Backup - Interconnectable

This Kidde i12040 is a 120 volt wire-in single sensor smoke alarm and has a 9 volt battery backup, which is included with the unit. Operating at temperatures from 40 to 100 degrees Fahrenheit, this unit detects flaming fires and utilizes ionization sensing technology, which detects invisible fire particles caused by fast, flaming fires sooner than photoelectric alarms. Featuring a one-button design for a smart hush feature and testing purposes, the alarm also features battery run down protection, which shuts the unit off when AC power is not present, reducing a low battery chirp.


  • NFPA and UL Recommended Dual Power Source
  • Hush Feature to Silence False Alarms
  • Interconnectivity with Up to 24 Devices
  • Tamper Resistant Housing
  • Red and Green LED Indicator Lights
  • Audible Low Battery Warning

Rated 5 out of 5 by 3 reviewers.
Rated 5 out of 5 by these smoke detectors met my expectations they installed very easily. they work fine... March 3, 2013
Rated 5 out of 5 by Plug and Play I ordered seven of these to replace contractor installed alarms that were at the end of their useful life. These were easy to install as the process is like changing the back-up battery. You twist the alarm from the base, lower the unit, unplug the wires, discard the old alarm, plug in the new one, twist back onto the base. Simple. February 11, 2012
Rated 5 out of 5 by It's the perfect replacement for the old model #1275. It's so easy to install. I like the "hush" feature. June 8, 2011
