Two-step shutdown performance: After the control box receives the alarm signal, the control fireproof shutter automatically closes to the neutral position to stop, after 5s~60s delation, it will continue to close to fully closed; or after the control box receives the first alarm signal, Control the fireproof shutter to automatically close to the neutral stop,continue to close to fully closed after receiving the second alarm signal.
Temperature controlled release performance:
lt is equipped with a temperature-controlled release device. When the temperature around the temperature sensing element of the release device reaches 73 °℃ ± 0.5°C, the temperature-controlled release device operates, and the roller blind is closed by its own weight.
The patented electronic limit motorwith the lock box, can realize the limitsetting without climbing high, avoidingto climb high or drill the ceiling to adjustthe limit twice in the later stage of the proj-ect, saving money and labour.
The new technology, the waterproof glueon the circuit board is fully covered, and itis not afraid of moisture, especially thebasement that has not been renovated,
and it is not afraid of water droplets on thecircuit board.
