Fire Detectors

Fire Detectors & Fire Detection Systems

Fire Detectors are used to detect smoke, flames or heat in a building as an early warning of fire. Types of detectors include aspirating smoke detectors, beam detectors, flame detectors, gas detectors, linear heat detectors, heat detectors, smoke detectors and detector testers.

Aspirating Smoke Detectors (ASD), consists of a central detection unit which sucks air using a fan through a network of sampling pipes and sampling holes to detect smoke, generating warning signals when appropriate. Aspirating Smoke Detectors are highly sensitive, and can detect smoke before it is even visible to the human eye.

Beam Detectors project a beam of infra-red light, the beam detector then registers the light and produces an electric signal. The electric signal of the beam detector is then processed by the detector which generates alarm or fault signals if any smoke or harmful substance distrube the light beam.

Fire Detection Systems are custom or complete packages of fire monioring systems and fire detection systems.  Fire Detection Systems use an assortment of fire detectors to detect smoke, flames or heat in a building as an early warning of fire.

A flame detector is a detector that uses optical sensors to detect flames. There are two general types of flame detectors, Infrared Flame Detectors and Ultraviolet Flame Detectors.

A gas detector are fitted with gas detecion sensors, they are devices which detect the presence of gases within an area. Usually as part of a gas detection system to warn about various gases which might be harmful to humans.  Gas detectors can be used to detect combustible, toxic and CO2 gases.

A heat detector is a device that responds to changes in ambient temperature. If the ambient temperature rises above a predetermined threshold an alarm signal will be triggered.  Heat detectors can be divided into two main classifications of activation, "rate-of-rise" and "fixed" however most sophisticated units are activated by both conditions.

Linear Heat Detection offers line type heat detectors that offer ultra-fast fire detection with pinpoint accuracy in extreme conditions where heat, frost or humidity places the utmost demands on technology. Linear Heat Detectors incipient fires in record time are very precise with highly sensitive sensors.

Commercial, industrial, and mass residential smoke detectors detect smoke and issue a signal to a fire alarm system. Smoke detectors work either by optical detection (photoelectric) or by physical process (ionization) or by both detection methods to increase sensitivity to smoke. Smoke detectors in large commercial, industrial, and residential buildings are usually powered by a central fire alarm system, which is powered by the building power with a battery backup.

Detector Testers are used to test all types of detectors they include smoke detector testers and heat detector testers.  Smoke detector testers work by releasing test smoke into the detector to test it whether it is working properly.  Heat detector testers work by altering the ambient temperature around the detector to test it whether it is working correctly.
