Thermal Activation Device for Aerosol Generator

» PRODUCT » Thermal Activation Device for Aerosol Generator

  • Stand alone thermal activation device

    Thermal Activation Device is a special temperature sensing components, which is different from normal heat detector, normal heat detector not have function of causing small current to start the suppression device, but this TAD have, and it can work completely stand-alone.

    • Specifications
    • Main Features and Characteristics
    • Application and Matters

    Thermal Activation Device AW-101 is an accessory of the aerosol fire extinguishing system, it is a new style of temperature sensing fire detection element, which mainly has two basic functions: one is to detect fire, another is to start the aerosol system to suppress fire.

    It senses changes in ambient temperature using the principle of electromagnetic induction to generate a pulse current and, at the same time, transmit a feedback signal to the fire alarm host.

    It works stand-alone, and Instantaneous current can be generated automatically during operation.

    It can well match aerosol and superfine dry chemical fire suppression because both of them require a small current to act.

    For its structure, please refer to our AW-101 INSTALLATION MANUAL, and for its working principle as below:

    • When the ambient temperature exceeds the rated temperature, the thermal element fusible metal begins to deform and release the moving pole with spring.
    • Under the action of spring, the magnet in the moving pole passes through the induction coil and makes the coil generate current.
    • The pulse current is output to the fire extinguishing device through the output terminal, and the feedback signal terminal which is non-polarity changes from the normal open state to the normal closed state.
