Active fire protection systems are an extremely important part of protecting property and the lives of the people within. An important factor that active fire protection systems share is that they involve action of some kind and ensures the alarms will function properly in the event of an emergency. Some examples of these actions include notifying of fire and smoke conditions, or slowing the progress of fire, or putting out the fire.
Active fire protection systems such as fire detection & notification systems, water sprinkler and spray systems are normally a mandatory requirement for rail & air transport terminals, high-rise buildings, schools, hospitals, and other large facilities. The duties of the fire protection system are basically detection, notification and extinguish the fire, control the fire, or provide exposure protection to prevent domino effects. For some specialised applications, systems like foam pourers or using inert gases or halogen based gases are used for flooding enclosed spaces, may be a more appropriate method of delivery than sprays or sprinklers.

- Fixed TemperatureFixed Temperature type heat detector makes use of a metal alloy. When the ambient room temperature exceeds the specified temperature for that particular device; the alloy melts and in turn give rise to an alarm. Normally the fixed temperature for these detectors is 115°F to 135°F. It is important to replace this type of heat detector once an alarm has been triggered; if the metal alloy melts, the detector is worthless.
- Rate of RiseRate of Rise type heat detector employs a sensing component; used to detect rapid or slow/steady increases in the ambient room temperature. This type is slightly more sensitive than the fixed temperature detector. This type of heat detector can detects sudden & abrupt change in temperature and also observes a 12°F to 15°F increase per minute within the room. This “rate of temperature increase” can be programmed as per room conditions.

The Linear Heat Sensor Cable is used as a detection device in Fire Detection & Alarm Systems. The Linear Heat Sensor Cable is effectively used to operate within areas of limited access and surveillance and within environmental conditions that would render other forms of detection, inoperable or subject to high levels of costly maintenance or false alarms.
The linear heat detection uses a single pair heat sensitive cable as the basis for its overheat/fire detection system. At a pre-selected temperature, the thermal sensitive polymer softens, allowing the signaling cores/ conductors - that are twisted together to form a spring like pressure between them - to move into contact with each other producing an alarm signal. A mechanical tension is constantly and uniformly maintained along the entire length of the detector. If conductor continuity is broken – with inner insulation maintained an open circuit fault condition will be signaled.
An outer extrusion of corrosion and abrasion resistant polymer maintains the conductor twisting over the full length of sensor cable installed and allows for its installation in external weather conditions and its application within more severe local environments. The authority having jurisdiction should always be contacted to confirm suitability of specified alarm temperature rating. It is advisable to allow a minimum of +11°C/+20°F between maximum normal ambient and minimum alarm temperature in order to avoid any potential false alarm conditions. Typical applications includes Cable Tunnel / tray protection, Road / Rail Tunnels, Rail Stations, Aircraft Hangars, Warehouses, Power distribution, Escalators & Elevators / Lifts etc.

Passive fire protectionwhich includes compartmentalization of the overall building through the use of fire-resistance rated doors, walls and floors. Organization into smaller fire compartments, consisting of one or more rooms or floors, prevents or slows the spread of fire from the room of fire origin to other building spaces, limiting building damage and providing more time to the building occupants for emergency evacuation or to reach an area of refuge.
Passive Fire Protection measures are intended to contain a fire in the fire compartment of origin, thus limiting the spread of fire and smoke for a limited period of time, as determined the local building code and fire code. Passive fire protection measures, such as fire-resistance rated smoke curtains, fire curtains, fire doors, and fire walls, usually expressed in terms of hours of fire resistance.
