How many smoke detectors/alarms needed?

Standards mandate the installation of at least one smoke alarm in every home. But you need to carefully consider whether one is enough.The recommendation is to have installation of multiple smoke alarms in your home. The positions as to where to place will be dependent on your floor plan. Metro Electrical 24 Hour Electricians will be happy to advise you on this matter. It strongly recommended to have one near or in bedrooms or corridors off bedrooms.

If you have a boarding house, guest house, hostel or holiday accommodation you must have one smoke detector/ alarm in each bedroom and near every corridor near a bedroom. If property has multiple levels you must have a smoke detector/alarm in the stairwell connected levels and any other levels without bedrooms must have a least one per level depending in size of each level.

Metro Electrical 24 Hour Electricians will be happy to advise you on your legal requirements.For added safety, smoke detectors/alarms can be interconnected so that all alarms will activate if one is triggered. This is law now for any properties constructed as of 1st May 2015.

When choosing a smoke alarm, it is important to know that different models use different methods to detect smoke.

Ionisation type smoke detectors/alarms respond faster to small smoke particles, such as those given off by burning paper, straw, or wood. Best suited to hallways, corridors and home offices.

Photoelectric smoke detectors/alarms respond faster to larger smoke particles, such as those produced by burning foam, rubber, plastics and other synthetic materials. Best suited to bedrooms and lounge and living areas.

The best detector type for your home is usually a photoelectric detector type. For the ultimate protection, a combination of both ionisation and photoelectric is recommended. Our knowledgeable electricians at Metro Electrical 24 Hour Electricians can help with all these decisions as to what is best suited for your property.

Non mains powered smoke detectors/alarms

If your property has battery smoke detectors/alarms and it has mains power they must be replaced, if it is a new property or existing property that has undergone significant renovations or prior to sale of a property and to all rental properties, any of these properties must have mains powered smoke detectors alarms installed.
