In addition to metal materials, the combustion performance of related materials has also been improved.The requirements for smoke toxicity caused by material combustion and the requirements for wind pressure deformation resistance, air permeability resistance and rain permeability resistance of wood fire doors as building exterior doors are deleted.In some cases, the building is not equipped with a central fire control system, and the fire protection operation procedure of the fire protection shutter is realized only by relying on the fire control electrical box of the fire protection shutter. In this case, when there is a fire, the fire signal received by the smoke sensor is directly transmitted to the fire control electrical box of the fire shutter.When the power goes out, the fire shutters can only be lowered by pulling the chain.
