Heat, Smoke, and CO in the First Generation
The Ajax FireProtect Plus adds a carbon monoxide sensor to the FireProtect detector. It therefore covers all three hazards—open fire, smoldering fire, and CO poisoning—in the same slim housing.
Features
- Heat, Smoke, and Carbon Monoxide Detection
- Slim-profile case — 31 mm thick
- Indoor installation — white or black
Carbon Monoxide
Odorless and invisible, CO is produced by any incomplete combustion: boilers, stoves, water heaters, and fireplaces. Detecting it is the only way to be alerted to its presence, and that alone justifies choosing this model for a home heated by gas, oil, or wood.
For a new installation
The FireProtect 2 (Heat, Smoke, and CO) offers the same coverage with a choice of power source. This model is suitable for adding to an existing fleet.
