Two-step Shutdown Performance: Once the control box receives the alarm signal, the controlled fireproof shutter automatically closes to the intermediate position and stops. After a delay of 5 to 60 seconds, it will continue to close until it is fully shut. Alternatively, after the control box receives the first alarm signal, it controls the fireproof shutter to automatically close to the intermediate position and stop. Then, after receiving the second alarm signal, it continues to close until it is fully shut.
Temperature-controlled Release Performance: It is equipped with a temperature-controlled release device. When the temperature around the temperature-sensing element of the release device reaches 73 °C ± 0.5 °C, the temperature-controlled release device activates, and the roller blind closes under its own weight.
The patented electronic limit motor of the Electronic Limit Fireproof Rolling Door Motor, equipped with a lock box, enables limit setting without the need to climb to a high position. This avoids the necessity of climbing to a high place or drilling into the ceiling for limit adjustment during the later stage of the project, thus saving both cost and labor.
