Product Description

The Kidde i4618 is an AC/DC powered, ionization smoke alarm that operates on a 120V power source with 9V battery backup. 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. The front-loading battery door allows user to change the battery without removing the alarm from the mounting bracket making battery replacement easy and convenient. 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 5-year limited warranty. 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.

Plugs into 2010 Firex i4268 Alarm-No Adapter Needed

Plugs into 2010 Firex i4268 Alarm-No Adapter Needed
I built a new home in 2010. The spare bedroom alarm just went bad and it has a Firex i4268. I purchased the Kidde i4268AC along with an adapter, because it sounded like an adapter was needed for compatibility. However, that was not the case. The new alarm clipped directly into all aspects of my old alarm—the cord plug and the cover both fit perfectly. Luckily the adapter was only a $5 (non-returnable) loss. I have provided photos of both my old and new alarms. Hopefully this saves someone some time and money!
