Photoelectric smoke detector
How often should I test my smoke detectors?
Home owners must test each smoke alarm at least once every 12 months by a Licensed electrician. Property managers or other nominated persons may act on behalf of an owner to maintain, test or replace alarms.
What can set off smoke alarms?
High humidity in the air can set off smoke alarms. The density of the moisture particles in the air trigger the alarm. The device has no way of distinguishing between light smoke particles and heavy moisture content. Insects.
What maintenance should be carried out on smoke alarms?
All smoke alarms require replacement every 10 years. After 10 years the efficiency of your smoke alarm may be compromised with accumulated dust, insects, airborne contaminants and corrosion of electrical circuitry. Smoke alarms make a warning 'beep' or 'chirp' when there is a fault or when the battery needs replacing.
Do you need to change batteries in hardwired smoke detectors?
This will insure that the power and wires are properly working in the smoke detector. Smoke alarms that are battery powered and that are hardwired into your electrical system should have their batteries changed annually. Another good date indicator is to change the batteries on New Year's Day.
Failure to test/service your smoke detector annually could
1.Lead to house fire tragedy
2.Void your insurance
3.Lose of life
