Smoke alarms are small, self-contained electrical units that signal an alarm warning when detecting the presence of smoke or fire. Smoke alarms may be hard wired into a building, and powered by a replaceable battery, or a combination of the two. There are many makes, models, and manufacturers of smoke alarms in Canada, ranging in price from under $20 to over $60.
