Product Overview

The Kidde 29HD is a compact optical smoke alarm powered by a 9V alkaline battery. Prominent test and hush buttons make it easy both to perform weekly tests to ensure proper operation of the alarm and to silence nuisance alarms caused by dust, steam, or fumes. The 29HD also features two anti-tamper mechanisms for peace of mind: one prevents casual removal of the alarm, while the other stops the alarm being fitted to the ceiling without a battery.

Easy to install and operate I had installed two of the FireAngel ST620 smoke detectors and they lasted a couple of years - no where near the 10 years that they were meant to last. So I decided to choose a different brand with a 5 year warranty and accept that I'll need to change them every so often. The Kidde 29HD has a very loud alarm, is easy to install and easy to test and operate. It is smaller than the FireAngel but the screw holes are in roughly the same place so they were dead easy to put up.
