Kidde Pro Series Photoelectric Smoke Alarm 120V - Brand New

The Kidde Pro Series Photoelectric smoke alarm uses photoelectric sensing rather than ionization, and that choice matters more than most people realise. Photoelectric sensors respond to the large, dense smoke particles thrown off by a fire that smoulders before it flames — a cigarette in a couch, wiring overheating inside a wall, a mattress catching slowly. Those are the fires that fill a house with smoke while everyone is asleep, and they are the ones photoelectric alarms catch soonest.

This is a 120V hardwired unit with a 9V battery backup, so it keeps working through a power cut. It interconnects with up to 24 compatible Kidde devices, which is the feature worth planning around: in a wired-together system, an alarm triggered in the basement sounds every alarm in the house at once. In a two-storey home that difference is measured in minutes.

Day to day it stays out of the way. One button handles both testing and the Hush function, so a nuisance trip from a hot shower or a smoky pan is silenced with a single press instead of a broom handle. Installation uses a quick-connect harness and a twist-and-lock bracket, and a 9V backup battery is included in the box.

Brand New Condition

This Kidde Pro Series Photoelectric alarm is brand new, unused and in its original packaging. It has never been opened or installed, so the full 10-year service life is ahead of it.
