Product Description

Amazon.com Product Description
The Kidde P12040 is a 120VAC powered photoelectric smoke alarm with 9V battery backup. This advanced smoke alarm has the ability to function as a stand-alone unit or in an interconnected system. The Kidde P12040 includes a test button, quick-connect power harness and offers a 10-year limited warranty. This alarm uses photoelectric sensing technology. Photoelectric sensing alarms may detect visible particles (associated with smoldering fires) sooner than ionization alarms. Ionization sensing alarms may detect invisible fire particles (associated with flaming fires) sooner that photoelectric alarms. 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. The Kidde model P12040 is a 120VAC powered alarm that includes a 9V battery backup to provide continuous protection during a power failure and included a quick connect power harness to make installation simple.
Other features: Test Button Tests units electronic circuitry, horn and battery; Red LED Alarm mode; Green LED - Steady on presence of AC power.

Customer Reviews

Spoke to Tech Support. There is no Hush Button on this Photoelectric model (and the Test Button does not act in this regard either).
Go with the BRK / First Alert, Model 7010B, which has the Silence Feature (for up to 15 minutes).
Options I was looking for:
Photoelectric - This is better than Ionization, in my case, where the alarm is just outside of a bathroom - where steam can set it off (I'm replacing an AC only, Ionization. Photoelectric is less sensitive to steam). Disposing of Photoelectric detectors after 10 years is also more environmentally friendly. They do not contain americium-241, which is under the positive plate of the Ionization chamber.
AC powered with 9V battery backup - The most desirable to have
Hush Button - The 9V battery backup will keep the alarm going, even if you cut power at the circuit breaker box - Need to be able to silence a false alarm, without having to remove the battery.

My home is linked together with 5 of these smoke detectors. One day one of them went bad and started setting all 5 of them off as they are linked to each other. Ordered an exact replacement, hooked it up and everything is working just fine again.
