Optical Smoke Alarms
Optical smoke alarms, also called photoelectric smoke alarms, 'see' smoke. They have a quick response to visibly smouldering fires (e.g. from foam filled furniture & overheated PVC wiring). They are also particularly good in areas where you can otherwise expect false alarms (e.g. near kitchens). We recommend the use of optical smoke detectors in living rooms, bedrooms and hallways.

What is an Optical Smoke Alarm?
Optical smoke alarms, sometimes called photo-electric smoke alarms, are the only sensor type for commonly used rooms such as living rooms, bedrooms, and hallways, where smoke from soft furnishings is more likely to be detected. These are considerably safer as they do not contain any radioactive material, in comparison to the phased-out technology of the ionisation smoke alarms. The advanced optical sensor, means that they are less prone to false alarms caused by cooking fumes and steam, making them suitable to be installed near, but never in kitchens and bathrooms.How do Optical Smoke Alarms work?
Optical smoke alarms, also known as photoelectric smoke alarms work by ‘seeing’ smoke produced by slow smouldering fires, often a result of soft furnishings burning. The alarm works by using the light scatter principle, this is where a pulsating infrared LED operates within the alarm sensor, pulsing every 10 seconds to check for smoke particles. Once smoke particles are detected within the optical chamber, it activates the sounder alerting occupants to the fire.What is the best place to install an Optical Smoke Alarm?
Optical smoke alarms are best situated in rooms where soft furnishings are, such as bedrooms, living rooms, hallways, and landings. Within these rooms, it is recommended by the manufacturer that the alarm is installed on the ceiling, however there are exceptions where smoke alarms can be installed on the wall. The best installation locations are specified in the user manual supplied with any alarm.
