Optical detectors are capable of detecting the visible smoke produced by materials which smoulder or burn slowly, i.e. soft furnishings, plastic foam etc.

With its ability to detect a wide range of fires, from smouldering to flaming types, the combined optical and heat multi-sensor detector is suitable for a range of applications.

Ionisation detectors, although rarely used today, are suitable for clean burning fires such as petrol, metholated spirits, or paint thinners as they are more sensitive to this type of fire than optical detectors.

A combined CO and heat detector provides very early warning of slow smouldering fires. Ideal for sleeping risks, the CO fire detector is also well suited to many applications where heat detection is insufficient but smoke detection causes false alarms.

The multi-sensor smoke, heat and CO detector is suitable for when the environmental conditions are challenging. It uses the three sensor elements together to accurately determine the presence of fire.

Rate of rise detectors detect abnormally high rates of rise of temperature.

Fixed temperature detectors detect abnormally high (static) temperatures.

Designed for use in buildings with high ceilings such as warehouses and atria, the beam smoke detector spreads a beam from one wall to another (up to a max of 100 metres apart) in order to detect smoke at higher levels.

The flame detector is ideal for protecting large open areas as it’s ideal for fast response to flaming fires typically caused by flammable liquids.

Air sampling detection works by actively drawing air from the protected area through sampling holes in a pipe network. Sampled air is then filtered before being analysed by detectors.

CCTV cameras relay images to the main computer where they’re analysed. Certain patterns are actively monitored to detect either visual smoke or infra-red radiation from heat.
