How to open the screen manually when the shutter door is dead?

The shutter door is dead and can be opened manually with a rocker.

1. The manual door is easy to open, and the manual rocker is open. This kind of door takes time and effort.

2. If a chain is installed next to it, you can pull the chain on the motor and pull it down directly to open it.

3. In case of power failure or failure, it is troublesome to open the shutter door, so it is necessary to check and maintain it frequently.

4. Use UPS to delay power supply. Many high-precision equipment will use UPS power supply, which is similar to the function of battery, but the principle and function are not exactly the same. It is similar to a special kind of fire lamp. When there is electricity in the power grid, UPS will supply power to the battery, but the principle and function are not exactly the same. UPS will not affect UPS when there is electricity in the power grid. Ordinary UPS is installed on the upstream power supply line of the power system. When the power supply fails, you can directly use the UPS power supply. At this time, the electric shutter door can be opened remotely as when there is electricity. However, the delay time of UPS has certain restrictions, such as 12 hours, 24 hours and other specifications. If it exceeds this time, it needs to be reconsidered.

5. Use a small generator to supply power. For most stores, power failure means that there is no lighting in the store and the equipment can't run. Many times, it often goes out of business. Coupled with staff salaries, equipment depreciation and other expenses, the store had to find another way of power supply, so small diesel generators came in handy. When the generator supplies power, it can supply power for most equipment in the store. However, it should be noted that there must be a professional electrician to design and control the circuit to prevent the generator from supplying power to the power grid. Moreover, the sudden power grid call will also burn out the generator. The electric shutter doors in front of many shops often have back doors. You can solve the circuit problem through the back door, turn on the generator and supply power to the electrical equipment. At this time, you can also control the electric shutter door with the remote control.
