What is Carbon Monoxide Detector ?

Introduction to Carbon Monoxide Detector

What is it?

Carbon monoxide detectors are devices that measure the concentration levels of carbon monoxide (CO) gas in the air inside a building. They detect and monitor the levels of CO, which can be an indicator of incomplete combustion in fuel-burning appliances, such as furnaces, water heaters, and stoves.

Why we use it?

We use carbon monoxide detectors to maintain good indoor air quality, improve occupant health and safety, and comply with building codes and standards.

How it works?

The detector typically contains one or more electrochemical cells, which produce a current when exposed to carbon monoxide. The device then calculates the concentration of CO based on the magnitude of the current produced.

Major brands that manufacture it

Some of the major brands that manufacture carbon monoxide detectors include Kidde, First Alert, Nest, and Honeywell.


There are different types of carbon monoxide detectors, including plug-in, hardwired, and battery-operated models. Some also feature additional functions, such as temperature sensing or wireless connectivity.

How do we select it?

When selecting a carbon monoxide detector, consider factors such as accuracy, response time, measurement range, power source, and communication protocols. Also, make sure the detector is certified by a recognized testing agency, such as Underwriters Laboratories (UL).

How to install it?

Carbon monoxide detectors should be installed in areas where occupants spend most of their time, such as bedrooms or living rooms. They should be mounted on a wall or ceiling at a height of approximately 5 feet above the floor, away from any obstructions that could interfere with airflow.

Wire connections required to receive the signals

The wire connections required to receive the signals from a carbon monoxide detector may vary depending on the specific device and building automation system. Typically, battery-operated models do not require wiring, while plug-in or hardwired models will require a power supply connection and a communication signal wire that connects to the building automation system or controller. It's important to refer to the manufacturer's installation instructions for proper wiring connections.
