Smoke, Fire & Gas Detection FAQs
Can air purifiers affect ionisation smoke alarms?
Yes, air purifiers may cause
ionisation smoke alarms to sound falsely. To prevent this from happening, position the air purifier as far away from smoke alarms as possible.
Please note: Ionisation smoke alarms contain a small amount of radio-activity and as such they are being phased out in the UK. It is recommended that you replace your ionisation smoke alarms with an
optical smoke alarm.
