Linear Heat Detection (LHD) is an important component of fire protection systems, as it is designed to detect heat along the length of a sensor cable. The sensor cable is made up of two conductors, both insulated by heat-sensitive polymers. When the ambient temperature meets or exceeds the detector's fixed temperature, the polymer melts, causing the steel conductors to make contact and initiate an electrical short that sends a signal to the fire alarm panel.
This signal then triggers the fire suppression agent to be released, or sets off the fire alarm system, depending on the configuration of the system. For example, if the LHD is connected to a fire alarm that initiates the fire sprinkler system upon alarm, when the heat from a fire melts the wire, the system is alerted, and the fire sprinkler valves open to allow water to flow in for a preaction system.
It's important to ensure that your LHD system is installed and maintained correctly by a qualified contractor to ensure it functions as intended and complies with building codes and NFPA standards.
Deluge systems are generally used in high-hazard areas such as power plants, aircraft hangars, and chemical plants.
Dry pendent sprinklers are typically installed in food process plants and box-in-box freezers where temperatures are below 40 degrees F.
Dry pipe sprinkler systems are generally used in cold climates and are highly effective in cold-temperature fire protection.
Early Suppression Fast Response (ESFR) systems are quick-responding, high-volume sprinkler systems that provide exceptional protection for high-piled storage occupancies.
Fire pumps are an essential part of many water-based fire protection systems. Fire Pumps are used to increase the water pressure (measured in psi) when the original water source is not adequate for the system it’s supplying.

Pre-action fire sprinkler systems employ the basic concept of a dry pipe system in that water is not normally contained within the pipes.
Wet pipe systems are the most common fire sprinkler systems. A wet pipe system is one in which water is constantly maintained within the sprinkler piping.
A special hazards fire suppression system is used to put out fires in areas where water damage from fire sprinklers can cause costly or irreparable damage to the assets being protected.
