Frequently Asked Questions About Linear Heat Detection Systems
Find out if a linear heat detection system is right for your facilities.
A linear heat detection system consists of heat-sensitive cables capable of detecting heat anywhere along their length. Linear heat detector cables are covered with heat-sensitive polymers within an insulated jacket. Once the ambient temperature meets or exceeds its fixed temperature, the heat-sensitive polymer weakens, which in turn allows the twisted spring steel conductors to make contact, which results in an electrical short that triggers an alarm signal and often initiates a fire suppression method, such as a wet or dry sprinkler system. Other variations of this technology include fiber-optic-based linear heat detection and confirmed-temperature linear heat detection technologies. Selection criteria are largely based on operational objectives, which Everon can help guide you through.
Unlike traditional spot-type heat detectors, which sense heat in a specific area and require testing at each point, linear heat detection cables can cover long distances and provide continuous monitoring with centralized testing. A linear heat detector can best be described as a continuous run of spot-type heat detectors. It is capable of sensing heat anywhere along its length and initiates an alarm once its fixed activation temperature is reached. Linear heat detection offers a cost-effective solution that provides maximum coverage over a large area. It is designed for use in harsh environments, is universally compatible, is approved for use in classified hazards, and includes straightforward installation and testing.
Linear heat detection cables can span over 10,000 feet, providing an ideal fire detection solution for covering large surface areas, such as traffic or rail tunnels, battery storage facilities, conveyer belts, warehouses, large production areas, and more. The outer jackets resist corrosion, chemicals, moisture, and extreme temperatures, which make them a great fit for harsh environments. Furthermore, they can be installed close to hazards to provide localized detection, enabling rapid response.
Because of their long service life and large area of protection, it is possible to install one line of heat-sensing cable to replace multiple, sometimes difficult-to-service, spot-type heat detectors. When replacing code-required heat detectors with an active linear heat detection solution, you reduce the cost of ongoing maintenance, including testing and serviceability.
Robust Advanced Detection Solutions
Detector selection criteria must consider structural, environmental, and operational performance objectives. The experienced professionals at Everon™ can help you identify suitability and proper application of the right solution to best meet your fire and life safety strategy.
Everon can install fixed and rate-of-rise heat detection systems designed to alert you when there are rapid increases in temperature, which may be a sign of a quickly spreading fire. Everon heat detectors then immediately alert building occupants, key stakeholders, and our monitoring centers so first responders can be dispatched to respond.
Everon can help you select ideal flame detection systems based on the hazard present and operational performance objectives. Flame-type fire detectors are often connected to automatic fire suppression systems to respond immediately in the presence of a flame.
Everon can help you select suitable high-resolution thermal imaging technologies that help you detect temperature anomalies in regions of interest (ROI), potentially before failures occur.
