      General Recommendations for Smoke Alarms in a 3-Storey House:

      1. Minimum Requirements:

      • One Smoke Alarm per Floor: At a minimum, you should have at least one smoke alarm on each floor of the house. This ensures that no matter where a fire starts, there is an alarm nearby to detect it.
      • Common Areas: Install smoke alarms in common areas such as hallways, living rooms, and stairwells. These are high-traffic areas where people are likely to hear the alarm.

      2. Bedrooms:

      • Inside Bedrooms: Install a smoke alarm inside each bedroom to ensure that occupants are awakened if a fire starts outside their room while they are sleeping.
      • Outside Bedrooms: Place a smoke alarm outside each sleeping area, preferably in the hallway or corridor leading to the bedrooms. This ensures that the alarm can be heard through closed doors.

      3. Additional Locations:

      • Kitchen: Install a smoke alarm in or near the kitchen, but avoid placing it directly above cooking appliances to reduce false alarms. Consider a heat detector instead if false alarms are a concern.
      • Living Room and Family Room: These areas are often where fires start due to electrical appliances or heating devices.
      • Basement and Attic: If your 3-storey house includes a basement or attic, install smoke alarms in these areas as well. Fires can start in these less-frequented spaces and spread quickly.

      4. High-Risk Areas:

      • Near Furnaces or Water Heaters: If you have a furnace, water heater, or other fuel-burning appliances, install a smoke alarm nearby.
      • Garage: If you have an attached garage, install a smoke alarm to detect fires that may start there and spread to the house.

      Specific Recommendations Based on Best Practices:

      Example Layout for a 3-Storey House:

      1. Ground Floor:
        • One smoke alarm in the hallway near the bedrooms.
        • One smoke alarm in the living room or common area.
        • One smoke alarm in or near the kitchen.
        • One smoke alarm in the garage (if attached).
      2. First Floor:
        • One smoke alarm in the hallway leading to the bedrooms.
        • One smoke alarm inside each bedroom.
        • One smoke alarm in the common area (e.g., family room or study).
      3. Second Floor:
        • One smoke alarm in the hallway leading to the bedrooms.
        • One smoke alarm inside each bedroom.
        • One smoke alarm in the common area (e.g., master suite or home office).
      4. Additional Locations:
        • One smoke alarm in the basement (if applicable).
        • One smoke alarm in the attic (if applicable).

      Total Number of Smoke Alarms:

      Based on the above layout, you would need a minimum of 10-12 smoke alarms for a typical 3-storey house. This number can vary depending on the specific layout and additional high-risk areas.

      Additional Tips:

      • Interconnected Alarms: Install interconnected smoke alarms so that if one alarm detects smoke, all alarms in the house will sound. This ensures that everyone is alerted regardless of where the fire starts.
      • Regular Maintenance: Test each smoke alarm monthly and replace batteries at least once a year (or as recommended by the manufacturer). Replace the entire unit every 10 years.
      • Combination Alarms: Consider combination smoke and carbon monoxide alarms, especially in areas near fuel-burning appliances.
