Features

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.

From the Manufacturer

There are only minutes to escape a house fire. The sooner you hear the smoke alarm, the sooner you can get out safely. Kidde interconnected ionization smoke alarms provide early warning against fire by linking together the smoke alarms in your home, dramatically increasing your ability to hear an alarm anywhere, regardless of where the fire starts. This alarm is a 120V AC powered ionization smoke alarm with 9V battery back-up and hush feature. This smoke alarm has the ability to function as a single unit or in an interconnected system. Install UL listed smoke alarms on every floor of your home, in hallways, inside bedrooms, and outside of sleeping areas and replace smoke alarms every 10 years. Ionization sensing alarms may detect invisible fire particles sooner than photoelectric alarms. Studies show both types will effectively detect either type of fire. For optimal protection, install both smoke alarm technologies in your home.

5.0 out of 5 stars How do you rate a smoke alarm?, August 26, 2009
By 
Rich (Boise, ID) - See all my reviews
Amazon Verified Purchase(What's this?)
This review is from: Kidde i12040 120V AC Wire-In Smoke Alarm with Battery Backup and Smart Hush (Tools & Home Improvement)
The purpose of a smoke alarm is to alert you to a fire in your home. Thankfully I have never been able to test this unit, and I hope I never have the chance. So I'll just review the other reasons I bought this product.

I bought two of these units to replace older Kiddie model 1275 units that were malfunctioning and going off regularly for false alarms. My main concern was compatibility since I have 10 units in my house and did not want to replace them all. These new units used the same wiring, connectors, and mounting frames as the old units which was perfect -- installation took less than a minute per unit. The new units work with the old units perfectly -- pushing the test button on the new ones set off all the alarms in the house, just as they should.

I did have some hesitation about buying new Kiddie units since the old Kiddie units were malfunctioning. (To be fair, only one was malfunctioning, but I was tired of messing with troubleshooting and decided to replace the last two options.) However, only 1 in 10 of my existing units was malfunctioning, and they are 6 years old (out of a reported 10 year lifetime). The smoke alarms were installed when I bought the house, so I can't be sure the failing unit was not dropped or otherwise abused before installation. So far the new units have not produced any false alarms and are working well.

5.0 out of 5 stars Does what its suppose to and some!!, May 9, 2008
This review is from: Kidde i12040 120V AC Wire-In Smoke Alarm with Battery Backup and Smart Hush (Tools & Home Improvement)
I needed to find a replacement for the older hard wired "Lifesaver"smoke detectors that were installed in my two 20 unit apartment buildings. It took me only 1 minute to punch out screw hole placement to existing set up. Rewired using the same set up and done. It works great and my tenants love the "Smart Hush" control to temporarily silence nuisance alarms. These will be my choice for all future replacements throughout each unit as needed.

2.0 out of 5 stars Ok so far ... Kidde's customer service is definitely not, November 28, 2009
By 
John Z. (Cincinnati, OH) - See all my reviews
Amazon Verified Purchase(What's this?)
This review is from: Kidde i12040 120V AC Wire-In Smoke Alarm with Battery Backup and Smart Hush (Tools & Home Improvement)
I had a house full of Kidde 1275 smoke alarms, and after several malfunctions (including one electrical problem causing it to literally "go up in smoke"), I replaced them with the i12040 ... only because I wanted something that would "drop in" with the current mounting system and wiring. That they did, and I've had no false alarms in the month they've been installed.

Why the 2 stars? Previous to purchasing, I contacted Kidde (via their customer service web page) to ensure the i12040 units had the same mounting system as the old 1275's and to ensure the wiring would be compatible with all the Kidde alarms on the system. Kidde never responded. I found out from a do-it-yourself web forum that these would work fine.

Kidde's customer support is notoriously poor. The old 1275 units were deficient in design and/or manufacture - and Kidde refused to acknowledge this. I won't give high marks to a company that won't respond to customer service issues.
