Smoke alarms detect fires in different ways to give you early warning. Find out about the types of smoke alarms you should consider for your property.

Types of smoke alarms

There are lots of different smoke alarms on the hardware store shelf, so it is important to understand which option is best for your property, and why.

The two types of smoke alarms used in Western Australia use either ionisation or photoelectric smoke sensors. The difference is in the smoke sensing technology used, which affects how the device reacts to a fire.

We recommend you use photoelectric smoke alarms that are mains powered to keep your household safe.

Smoke alarms for people with disability

If hearing, vision or immobility may impact your reaction to smoke alarms, we recommend that your smoke alarms be interconnected. This means when one smoke alarm detects a fire, all alarms throughout the house will sound and alert all the occupants. You may also want to think about getting a smoke alarm that is connected to a monitoring centre.

The standard smoke alarm (designed to emit 85 dB at a distance of three metres) is suitable to wake most people who have mild to moderate hearing loss. However, if you're deaf or have severe hearing loss, you may have difficulty in hearing standard smoke alarms and evacuation systems.

Smoke alarms for the deaf and hard of hearing have strobe lights and/or vibrating pads that can be interconnected with standard audible alarms in different locations within the home. When the smoke alarm sounds, the strobe will flash and the vibrating pad will vibrate.
