Kidde 900-0114-A Hardwired Co Smoke Alarm 120VAC 85db

Product Description

The KIDDE 900-0114-A is a hardwired combination carbon monoxide and smoke alarm designed for permanent residential installation. It operates on 120 VAC at 60 Hz with alkaline battery backup to maintain protection during power outages. The electrochemical CO detection technology provides reliable sensing, and the integrated 85 dB horn at 10 feet delivers a loud, clear alert. A sealed sensor cover protects the detection cell from contaminants prior to and during installation, reducing nuisance trips. Licensed electricians and fire-safety contractors typically install this unit as part of a whole-home interconnected alarm network.

This alarm is suited for residential and light commercial applications where hardwired CO and smoke detection is required by code. The unit supports up to 24 interconnected devices, allowing an entire structure to sound simultaneously when one alarm triggers. An adjustable mounting bracket simplifies ceiling or wall placement and allows fine alignment without additional hardware. The tamper-resistant locking feature deters unauthorized removal of the battery or alarm unit, which is useful in rental and multi-family settings.
