What are Carbon Monoxide Alarms and Smoke Detectors?

Carbon monoxide alarms and smoke detectors are essential safety devices designed to protect your home and family from life-threatening hazards. A smoke detector alerts you to the presence of fire or smoke, while a carbon monoxide (CO) alarm detects the invisible, odourless gas that can be deadly if inhaled in high levels.

These devices are vital for early warning in emergencies and are recommended (or legally required) in homes, apartments, and commercial buildings.

FAQ

What’s the difference between a smoke detector and a carbon monoxide alarm?

A smoke detector senses smoke particles from fires, while a carbon monoxide (CO) alarm detects carbon monoxide—a colourless, odourless gas produced by burning fuels like gas, wood, or oil. Both devices are essential for home safety.

How often should I test my smoke and CO detectors?


You should test your alarms once a month by pressing the test button and replace the batteries at least once a year, or as recommended by the manufacturer.
