The TH218SS is a Digital Linear Heat Detection (LHD) cable with a 218°C (424°F) fixed temperature activation rating. The Very High Temperature coated linear heat cable is manufactured from Silicone rubber, with the outer sheath being developed to withstand prolonged exposure to high temperatures. Commonly used in high temperature areas such as cooker hoods and engine bay protection, hazardous and safe areas where prolonged heat exposure is expected. It is supplied in 100m, 200m, and 500m lengths.
Proline Digital Linear Heat Detection Cable uses fixed temperature detection technology to provide an easy method for sensing changes in temperature levels. The cable can offer alternative overheat protection in a vast range of applications and environments, from tunnels, cable trays, warehousing to sensing changes in temperature within escalators and other applications where many risks of fire are hidden from view.
The digital linear heat detection cable can be directly connected to a single zone of a conventional fire alarm control panel, or, using an addressable zone/switch monitor, the digital linear heat detection cable can easily be interfaced to an addressable loop.
Digital linear heat detection cable is comprised of a pair of twisted low resistance, tri-metallic conductors, sheathed in advanced temperature sensitive polymers. When the cable reaches the required temperature the two twisted cores will fuse together, with a fire triggering resistor attached to the input interface and a single core of linear heat cable to activate an alarm at the main fire panel.
