Thermocable's Programmable Temperature Sensing (or 'analogue') product is the first cable-based resettable linear heat detector approved to EN54-22. It’s also the only type of cable-based linear heat detector that has automatic ambient temperature adjustments.

The system identifies fires or overheat conditions by continuously measuring changes in electrical resistance along the detection cable. An alarm is triggered once the resistance falls below a set threshold, which is determined by the desired alarm temperature (chosen by the user).

Thermocable’s UL certified, high-quality ProReact Programmable Temperature Sensing LHD system meets the strict requirements of EN54-22:2015+A1:2020 as certified by VdS Global. It has been approved to Class A1I, A2I and BI and can be used in wide range of environments. Unaffected by dirt, dust, and damp, the system is a cost-effective, resettable, line-type heat detector that can be used in applications less suited to other types of fire detectors
