General Overview
Introduction
Thermocable’s ProReact EN Analogue Linear Heat Detection (LHD)
system comprises of ProReact EN Analogue Linear Heat Detection (LHD)
sensor cable, a ProReact EN Analogue Composite Control Unit and a
ProReact EN Analogue end of line unit. The system oers alternative
overheat protection in a vast range of applications and industries, from
power generation to oil and gas industries.
The ProReact EN Analogue technology oers separate Pre-Alarm and
Alarm outputs in order to maximise functionality, coupled with open
and short circuit detection and discrimination.
Ambient temperature compensation maintains alarm temperature
accuracy. The system is also resettable following an overheat or re
condition if the components are not exposed to temperatures above
the maximum recoverable temperature.
Using a zone or switch monitor, or input/output module, the
ProReact EN Analogue LHD system can easily be interfaced to
an addressable loop. Alternatively it can be directly connected
to the initiating zone of any conventional re alarm control panel
(as shown below).
