Linear Heat Detection

Linear Heat Detection Systems provide a cost-effective and reliable fixed temperature heat detection solution that is suited to a wide range of applications.

Linear heat detection systems are adaptable to a broad range of environments and applications where standard fire detection methods cannot be utilised due to conditions such as increased airflow and harsh environmental conditions.

They are often used for providing fire protection in areas such as;

• Tunnels
• Car parks
• Recycling plants
• Food processing facilities
• Conveyor systems
• Cable Containment

Heat Sensing Cable is comprised of two tri-metallic conductors that are covered with advanced temperature sensitive polymers. The two conductors are twisted together, and a protective outer sheathing is wrapped around them. Once the temperature sensitive polymer reaches its rated temperature it melts, causing the two conductors to come into contact. The resulting short circuit, signals to the fire alarm control panel that a fire (or extreme heat) has been detected. Once a fire has been detected, or if the detection cable becomes damaged, the affected length of cable can be easily replaced; the damaged section can be removed, and new section spliced in its place. 

Linear heat detection cable can be directly connected to a single zone of a non-addressable fire alarm control panel or easily interfaced to an addressable loop using an addressable zone/switch monitor.
