Are smoke and Carbon Monoxide detectors the same?

Smoke Alarms are vital for warning individuals of potential fires, providing them with sufficient time to evacuate the building safely. These alarms operate by utilising Photoelectric or ionisation sensors to detect smoke particles present in the air. Photoelectric sensors are more sensitive to large smoke particles produced by smouldering fires, while ionisation sensors are more sensitive to small smoke particles produced by flaming fires.

Carbon monoxide detectors are intended to warn individuals of the presence of carbon monoxide (CO) in the air. CO is a by-product of incomplete combustion and can originate from various sources, such as gas hobs, fireplaces, and car exhausts. Due to its colourless, odourless, and tasteless nature, individuals can inhale large amounts without detection, leading to carbon monoxide poisoning. Symptoms of carbon monoxide poisoning may include headache, dizziness, weakness, nausea, vomiting, chest pain and confusion. In severe cases, it can result in loss of consciousness and death.

Combined smoke and carbon monoxide detectors are gaining in popularity as they offer extensive protection against fire and CO threats. These devices employ photoelectric and ionisation sensors to detect smoke and an electrochemical sensor to detect CO. This enables them to give advanced notice of both smouldering and flaming fires, as well as carbon monoxide leaks.
