Smoke and heat alarms need to be tested every year, usually when the fire doors are being tested to minimise disruption to the tenant/owner. Every house, home, unit is required to have a suitable number of smoke alarms installed from 1 May, 2006. Smoke alarms should be located on every level of your home. You should replace the battery in each smoke alarm at least once a year. We can test your smoke alarms @ $15 + GST each and if needed replace hard wired photo-electric smoke alarms @ $180 + GST and thermal/heat alarms @ $200 + GST.
