  • The structure and principle of temperature detector

     The temperature detector is sensitive to the temperature parameter response at a certain point in the detection area or around a continuous route. It includes constant temperature detector, differential temperature detector and differential constant temperature detector.  A constant temperature ...

  • Flame detector

    Currently, flame detector is used to distinguish infrared flame and ultraviolet flame. The response speed of flame detector is fast, the sensitive element sends out a signal a few milliseconds after receiving the flame. It is suitable for flammable and explosive places with fire and smoke. It has...

  • Common failures of fire detectors

     Fire detectors play an important role in our lives.Fire detectors can monitor whether there is a fire in the environment. Once a fire occurs, the characteristic physical quantities of the fire are converted into electrical signals,such as smoke concentration, temperature, gas,radiation intensity...

  • Detection method of fire control linkage control equipment

    The fire control linkage control can cut off the relevant air conditioner in the alarm area automatically after the fire detector detects the fire signal, close the fire valve on the pipeline, stop the relevant fan change, open the exhaust valve of the relevant pipeline, and close the electric fi...

  • Detection methods of different detectors

    Different detectors have different detection methods. There is the detection method of point type smoke detector. Use a smoke generator to release smoke to the detector, check the detector alarm confirmation light, and the fire alarm signal display of the fire alarm controller. Eliminate the smok...

  • Addressable fire detector

    Each probe of the addressable fire detector is programmed with an address. When there is an alarm, it can be located accurately according to the probe address which protection area has a fire or false alarm. The fault range can be  found quickly when the line has a roadblock. The addressable fire...

  • Common failures of fire detectors

    The fault phenomenon is that the fire alarm controller issues a fault alarm, the main power fault light is on, printer printing main power failure. The cause of the failure may be a mains power failure, poor power cord contact, main fuse blown, etc. There are the elimination methods.It should be ...
