Tyco 631H-F Marine Conventional Fixed Heat 90°C Detector 516.600.033
Tyco 516.600.033 631H-F Heat 90°C Detector – Marine Use Only
Tyco 516.600.033 631H-F Heat 90°C Detector – Marine Use Only
The Tyco 631HF (516.600.033) is a 90°C Fixed Heat Detector that used two networked thermistors in a bridge configuration to provide a fast response. This depends both on absolute temperature and notes the change in the temperature. The Rate-of-Rise/fixed temperature Detectors can be used in areas where Smoke Sensors are unsuitable due to environmental conditions such as smoke and dust.
Heat detectors offer an acceptable, but less sensitive alternative to smoke detectors if environmental conditions rule out their use. The 611H-F (fixed temperature) detector detects abnormally high (static) temperatures.
