• Smoke Alarms Save Lives

    Working smoke alarms save lives. Keep your family and your home safe by ensuring you have properly functioning smoke alarms. Here is some information you should know about smoke alarms.

    The Ontario Fire Code requires a working smoke alarm on every story of your home and outside all sleeping areas. For added protection, install smoke alarms inside all bedrooms (especially if people sleep with their bedroom doors closed).

    Classes of smoke alarms

    Typically, newer homes have one type of smoke alarm that is common throughout the house, with the exception of the sleeping level, which may have a combination smoke/carbon monoxide alarm.

    Older homes may have a combination of battery and hardwire type of smoke alarm depending on the age of construction.

    Smoke alarms can offer different features and applications, so choosing the right alarm is important.

    • Power Source – these type of smoke alarms are electrically powered, battery powered or a combination of both.
    • Technology – most smoke alarms employ either ionization or photoelectric technology. Ionization alarms may respond slightly faster to flaming-type fires, while photoelectric alarms may be quicker at detecting slow, smouldering fires.
    • Interconnected – Interconnected smoke alarms are equipped with a feature so when on goes off, they all go off.

    Inspecting/testing smoke alarms

    It is important to test your smoke alarms every month using the test button. It is also a good idea to test the alarm periodically with smoke by using smouldering cotton string or an incense stick following the manufacturers instructions.

    It is recommended to seek the assistance of a certified electrical contractor when performing any residential electrical repairs.

    Replacing a smoke alarm

    If you must replace a hardwired, interconnected smoke alarm due to malfunction, be sure to replace them all with the same manufacturer make and model to ensure the alarms can communicate with each other. Mississauga Fire and Emergency Services (MFES) would like to remind homeowners to follow manufacturer guidelines and instruction when replacing or installing new smoke alarms and carbon monoxide alarms.

    Smoke alarms and carbon monoxide alarms provide an early warning signal and are the first line of defence in the case of emergency inside the home. It is against the law to tamper with or remove the batteries from smoke alarms.
