How to Maintain Smoke Alarms:
Check the alarms are firmly secured in the correct location – Double sided tape is not acceptable – so make sure you do it properly.
Check the required power source is connected and operating. Where a mains powered smoke alarm is installed, alarms will have a visual display /light to indicate that mains power is connected and this should be easily seen when standing beneath
Test the smoke alarm during routine inspections, or at least every six months
Check the smoke alarm(s) for a build-up of dust and cobwebs. Vacuum around the smoke alarm vents with a soft brush at least every 6 months
Check the smoke alarms are within their service life. Smoke alarms require replacement every 10 years. The date for replacement is often located on the unit.
Replacing batteries annually, where appropriate. Mains powered smoke alarms have back-up batteries – they can either be a 9V battery which requires to be changed annually while some models have a rechargeable non removable battery which does not need to be changed during the life of the unit.
This maintenance routine should be done at each inspection or at intervals otherwise stated. Please note: A licensed electrical contractor is required to disconnect or install mains powered smoke alarms. All other smoke alarm maintenance does not require a licensed electrical contractor.
