At a Glance



The Kidde i12040 smoke alarm offers a tamper-resistant feature to deter vandalism or theft and a smart interconnect system that connects with up to 24 Kidde devices–including other smoke alarms plus carbon monoxide and heat alarms. The battery-backup feature (9-volt battery included) provides protection even during power outages when many CO incidences occur. It has a large mounting base that helps protect surface paint from dirt and covers imperfections, and its pre-stripped wiring harness has an easy-off cap and tinned strands to increase conductivity.

By pressing the hush button, you can easily and safely silence nuisance alarms caused by non-emergency situations, such as overcooked dinners. This feature desensitizes the alarm for approximately seven minutes. During this time, the alarm chirps every 30 to 40 seconds. If the smoke is too dense, the hush feature is overridden and the alarm still sounds, and the alarm automatically resets at the end of the seven minutes. This convenient safety measure eliminates the temptation to remove the alarm’s battery, which creates an unsafe situation.

The Kidde i12040 smoke alarm uses ionization sensing technology, which 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 recommends that both ionization and photoelectric smoke alarms be installed to insure maximum detection.
