Digital Linear Cable Type Heat Detector;
It has been produced for use in places where it is not possible to apply the widely used point fire detection systems due to ambient conditions. Linear detectors are produced at different detection temperatures at fixed temperature values such as 70°C, 90°C, 180°C and are selected and applied according to the basic requirements of the area to be protected against fire. Linear heat detectors are available in chemical and physical corrosion resistant options.
Anolog Cable Type Heat Detector
It can be operated as a constant heat or rate of rise detector. An LHD analog control panel is also used with the cable. Alarm temperatures can be set via this device. They are products that can be set to an acceptable value in the field (depending on the cable length) via the LHD Analog Control Panel. It can be integrated into other detection systems with the outputs to be received via the LHD Anologous Control Panel.
Digital or Anolog Linear Heat Detectors, together with the LHD Control Panel, provide safe detection especially in Ex-Proof areas by using Zener Barrier or Galvanic Isolator.
