Fire Detector
NFPA 72, National Fire Alarm and Signaling Code, defines a detector as a device suitable for connection to a circuit that has a sensor that responds to a physical stimulus such as gas, heat, or smoke.
NFPA 72 also defines an Automatic Fire Detector as a device designed to detect the presence of a fire signature and to initiate action.
Accessories
There are many kinds of automatic fire detectors such as air sampling-type detector, carbon monoxide detector, smoke detector, heat detector, combination detector, fire-gas detector, radiant energy-sensing fire detector (flame detector), gas detector, line-type detector, multi-sensor detector, projected beam-type detector (beam detector), and fiber optic linear heat detector.

Especially, fiber optic linear heat detector (LHD) is the latest, fast-sensing, and robust detector designed specifically to detect a fire anywhere along the length of the fiber optic linear heat sensing cable over a distance of several kilometers.
Fiber optic linear heat detection systems utilize fiber optic distributed temperature sensing (DTS), one of the key technologies available within this field. Following are some of the applications where fiber optic linear heat detection systems are used:
• Tunnels – Road, rail, and metro
• Underground cable trays and culverts
• Underground telecom culverts/tunnels/monitoring
• Underground power culverts/tunnels/monitoring
• Logistics center
• Warehouses and freezers
• Car parks
• Conveyor belts
• Large industrial facilities
• Aircraft hangars
• Tank farms
• Escalators
NFPA 72 defines a fire detector as “A device suitable for connection to a circuit that has a sensor that responds to a physical stimulus such as gas, heat, or smoke.”
Air Sampling-Type Detector (ASD)
Air Sampling-Type Detector or Aspirating Smoke Detector (ASD) is a detector that consists of a piping or tubing distribution network that runs from the detector to the area(s) to be protected.
An aspiration fan in the detector housing draws air from the protected area back to the detector through air sampling ports, piping, or tubing. At the detector, the air is analyzed for fire products.
Flame Detector
Flame detectors are categorized as ultraviolet (UV), single wavelength infrared (IR), ultraviolet infrared (UV/IR), or
multiple wavelength infrared (IR3).
Flame detectors are known for their fast response to open fires. Applications vary from indoor to outdoor and from hydrocarbon to non-hydrocarbon fuels. Summarized below are some of the applications:
• Chemical Industry
• Conveyor Belts
• Engine Rooms
• Generator Rooms
• Pharmaceutical Industry
• Gas Service Stations
• Oil and Gas Pipeline and Pumping Stations
• Recycling and Waste Processing Plants
• Refineries
• Tank Parks
• Wind Turbines
