Straightforward, Reliable and Compatible

The ProReact range of digital linear heat detection cables is designed to trigger a response when a specific temperature is reached. If the temperature surrounding the cable reaches the activation temperature the two cores quickly come into contact and trigger an alarm. These cables are known as “digital” because they are “off” below the activation temperature and irreversibly switch “on” when the activation temperature is reached. The following alarm temperatures are available:

68⁰C (155⁰F)
78⁰C (178⁰F)
88⁰C (190⁰F)
105⁰C (221⁰F)
185⁰C (365⁰F)

Rapid Response

ProReact Digital LHD cable has been designed to be simple to install and extremely reliable thus providing guaranteed protection year after year. Since the cable only responds to an overheat situation it works just as well in noisy, dusty or hazardous environments where other types of detectors may false alarm. Through design, the cable is compatible with any conventional or addressable fire alarm control panels or other building management systems.
