Earlier Alerts for Smouldering Fires - thanks to the optical sensing chamber
An optical sensing chamber 'sees' smoke as it enters, responding particularly well to the thicker white smoke produced by slow-burning, smouldering fires. Sensor geometry focuses on larger particles so alarms trigger quickly when smoke density increases.
Faster detection of smouldering fires gives occupants more time to wake and evacuate, especially during the night when slow-burning sources can develop unnoticed.
Fewer Nuisance Alarms - with an advanced optical sensor
Sensor design reduces sensitivity to small airborne particles typically produced by cooking fumes and vaping, lowering the chance of false alerts. Manufacturer guidance recommends avoiding installation close to kitchens and bathrooms to further reduce nuisance triggers.
Reduced false alarms help avoid unnecessary disturbances and the temptation to disable alarms, maintaining reliable protection for longer.
Low Maintenance for a Decade - thanks to the 10-year sealed battery
A sealed battery is fitted for the expected lifetime of the unit, removing the need for periodic battery replacement during normal use. The battery is not user-replaceable, simplifying ownership and reducing maintenance tasks.
One fit-up and forget routine keeps the alarm active for its full service life, a practical advantage for landlords, busy households and holiday accommodation.
