The working principle of temperature sensing detector

Temperature sensing fire alarm detector is suitable for shopping malls, hotels, shops, warehouses, engine room and other civil and industrial sites. The detector has the advantages of high sensitivity, stable and reliable, low power consumption, beautiful and durable, easy to use, can be matched with the security system. Here we introduce the working principle of temperature sensing detector.

Under normal circumstances, temperature detector about once every 5-6 seconds indicating exhibit of lanterns shiny look. Automatic detection of the temperature change in the surrounding environment of the detector, and according to the use environment for automatic sensitivity compensation. When the ambient temperature is close to the alarm value, the detector will accelerate the intelligent operation of temperature trend, at the same time the alarm indicator light starts to flash. If the calculation results meet or exceed the alarm value, the detector red LED light remains light, alarm, and start the relay output. When restoring the environment temperature to normal state, the detector will automatically return to normal working condition.

Note: the detector alarm, output relay passive contact, contact capacity 1A/24VDC, the jumper detector PCB board, set to normally open and normally closed contact output. The factory default settings for normal closed contacts jumper.
