Replacing BRK / First Alert Smoke Alarms

I replace hardwired BRK / First Alert smoke alarms with the SM6W10A ($69.99 installed) or the SC6W10A smoke/CO combo ($109.99 installed), plus a $99.99 service fee per visit. We match the brand already in your home, and I test the interconnect before I leave.

How do I know if my alarms are BRK / First Alert?

BRK and First Alert are the same family of alarms, and plenty of Lower Mainland homes have their hardwired units. The logo on the front is often worn off, so check the label on the back. Most hardwired alarms twist off their mounting plate. The label shows:

If the alarm is too high, or you'd rather not take a hardwired unit down, leave it. I read every label on the visit.

How old is too old for a smoke alarm?

Manufacturers say to replace smoke alarms 10 years after the date of manufacture. Pressing the test button tells you the horn works. It doesn't tell you how old the sensor is.

BC's Office of the Fire Commissioner recommends marking the installation date on each alarm. Our guide on how long smoke alarms last has more.

What are the signs a BRK alarm needs replacing?

Chirp patterns differ between models. When in doubt, see beeping smoke alarm repair.

Which BRK models do you install?

ModelWhat it isInstalled
SM6W10A120V hardwired photoelectric smoke alarm, sealed 10-year lithium backup$69.99
SC6W10A120V hardwired photoelectric smoke and CO combo, sealed 10-year lithium backup$109.99

BRK lists both as conforming to CAN/ULC-S531 for smoke alarms and CSA 6.19 for CO alarms, the Canadian standards, and says the sealed battery needs no replacing for the life of the alarm. Our photoelectric guide explains the sensor type.

What do I get for the $99.99 service fee?

The $99.99 service fee is charged once per visit, not per alarm. What you get:

Can I switch to Kidde instead?

Yes, but it's all or nothing on that interconnect. Hardwired interconnected alarms should be one brand on the same interconnect. So:

Here's a typical Maple Ridge rancher with 4 smoke alarms and 1 combo, both ways:

LineBRK / First AlertKidde
Service fee$99.99$99.99
4 smoke alarms$279.96$319.96
1 combo alarm$109.99$119.99
Total before GST$489.94$539.94

Selling the house or turning over a rental?

A home sale or a new tenant is a good time to check the dates. The written record lists every alarm's location, type and manufacture date, which is handy if a buyer, tenant or insurer asks.

Gas heat or an attached garage? An SC6W10A in the hallway near the bedrooms adds CO detection for $40 more. See CO alarm installation in BC. Several units? See our strata and landlord service, or start at smoke alarm installation in Vancouver.

Frequently asked questions

How much does it cost to replace a BRK / First Alert smoke alarm?
One BRK / First Alert SM6W10A hardwired smoke alarm comes to $169.98 before GST. That's the $99.99 service fee plus $69.99 installed. The SC6W10A smoke/CO combo is $109.99 installed, and every extra alarm on the same visit adds only its installed price.
Where do I find the date on my BRK / First Alert alarm?
Twist the alarm off its mounting plate and look at the label on the back. It shows the model number and the date of manufacture. Replace the alarm 10 years after that date, not 10 years after it went up.
Can I mix Kidde and BRK alarms on the same interconnect?
We don't. Hardwired interconnected alarms should be one brand on the same interconnect. We match your home's existing brand, or if you'd rather switch, I replace every alarm on that interconnect so it's all one brand. Then I test the interconnect.
My BRK alarm keeps chirping after a new battery. Is it done?
Often it is. A chirp that keeps going after a fresh battery usually means end of life or a fault. Check the date on the back, and if it's close to 10 years or past it, plan to replace it. Our beeping smoke alarm page covers the other common causes.
Should I replace all my BRK alarms at once?
If they went up together, usually yes. They'll all reach 10 years around the same time, and one $99.99 service fee covers the whole visit, however many alarms I replace. Doing them together also keeps the whole interconnect on the same model generation.
