Smoke Alarm

Smoke alarms are designed to detect smoke in the air and alert you with an audible warning. It is the law in Ontario to have working smoke alarms on every story of a home and outside all sleeping areas. It’s important to test your smoke alarms regularly by pressing the test button on the device. Always read the manufacturers instructions.

Smoke alarms can also be tested using specially designed testing kits that employ a non-flammable, non-toxic, silicone free aerosol smoke tester in addition to an extension pole for hard to reach devices.

Depending on the environment, you may choose to use smoke alarms that are Battery Operated only, which use either standard alkaline batteries or have built-in, longer-lasting Lithium-ion batteries or Hardwired with Battery Back-up which connect to a building's electrical power source and utilizes built-in batteries for back up power should building power be disrupted.
