Is your smoke alarm working? It’s a good time to check

Date of Issue: Friday, March 6, 2026

With the time change on the horizon this weekend, it’s a good reminder to change your smoke and carbon monoxide alarm batteries and make sure they are working properly. 

“Working smoke and carbon monoxide alarms are one of the most effective ways of protecting you, and those you care about, from fire and the dangers of CO gas” said West Kelowna Fire Rescue Chief Jason Brolund. “Each year when our crews do their neighbourhood smoke alarm campaign, about half the homes we visit have an issue with their smoke alarms whether they are expired or missing batteries. Most people are unaware their alarms are not working so it’s a good idea to check.”

Smoke and CO alarm installation 

• Install smoke and carbon monoxide (CO) alarms on every level of your home, in each bedroom, and outside every sleeping area.
• Large homes may require additional alarms.
• Place alarms on the ceiling, or up high on a wall, and keep them at least three metres away from the stove to avoid false activations.
• Alarms are most effective when used in conjunction with proper device care, and pre-planning.
• Refer to the manufacturer's instructions for correct installation, maintenance and lifespan.

Smoke and CO alarm maintenance

• Check your alarms monthly.
• Change the batteries at least once a year
• Replace alarms every 10 years.

If you have a broken or expired smoke and CO alarm, you can replace it and drop it off for free at the nearest Recycle BC location to you. There are also special smoke and CO alarms for people who are hard-of-hearing or deaf, which feature strobe lights and bed shakers.

Planning for a fire

When there is a fire, smoke spreads fast. Working smoke and CO alarms give you early warning so you can get outside quickly. By the time you hear an alarm, you may have less than two minutes to evacuate safely. Plan and practice your home fire escape plan so everyone in your home knows what to do and can act fast when the smoke and CO alarm sounds. Remember, a closed door can slow the spread of smoke, heat, and fire.
