What is a fixed temperature heat detector?
Consequently, what is a fixed temperature?
FIXED TEMPERATURE: If the temperature of the center disk rises to the sensor's rated temperature, the fixed temperature element activates. This closes contacts in the sensor and transmits an alarm condition to the fire alarm control panel.
Likewise, what is a spot type heat detector? Spot Heat Detector. Heat detectors are used in confined areas for detection of fires around hazardous locations. The detector is a thermistor type, enabling adjustment of temperature response by the controller.
Beside this, how does a heat detector work?
A heat detector is a fire alarm device designed to respond when the convected thermal energy of a fire increases the temperature of a heat sensitive element. The thermal mass and conductivity of the element regulate the rate flow of heat into the element. It is triggered when temperature increases.
