Thermal Activation Device AW-101 is an accessory of the aerosol fire extinguishing system, it is a new style temperature sensing fire detection element, which mainly have two basic functions: one is to detect out 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 pulse current, at the same time, transmit feedback signal to 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 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 began 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 make 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 normal open state to normal closed state.

Installation and Commissioning
before do installation job please red installation manual carefully, and inspect each thermal activation generator one by one according to the following methods, and can be put into use after confirmation:
- Inspection method: check the integrity of housing, the housing or shell shall be free of obvious indentation, deformation and fracture; the thermal element (fusible metal) shall not all off or deform; accessories should be complete.
- Installation method: Wire and cable connection to the activation terminal and signal feedback terminal, it should be connected by using of “o” shape crimping terminal to connect; pull out the safety pin carefully, and install the device, and install it in the specified location; connect the wire or cable with the fire extinguishing system; installation size as per INSTALLATION MANUAL.
- Installation Precautions: 1. Forbidden to use violence to pull out the safety pin; 2. After pull out the safety pin, check whether the thermal element is fastened, forbidden to use in case of serious looseness; 3. the wire (cable) should be shielded flame retardant wire; 4. forbidden to pull out the safety pin after wire connection, should be before wire connection; 5. during installation and use, forbidden to touch the thermal element (fusible metal).
Transportation and Preservation
