Optical Smoke Alarm Information

These smoke alarms are ideal to detect smouldering fires that produce large smoke particles. These typically come from bedding or furniture fires.

Optical smoke alarms aren't suseptible to going off when the toaster burns your toast so they are fine to be located close to a kitchen, in a hallway for example.

They way an optical smoke alarms works is by a small pulsating light beam hitting a receptor and if a large particle of smoke gets in the way of that beam, the alarms sounds.
