Fire shutter refers to the shutter that can meet the requirements of fire integrity and heat insulation in a certain period of time together with the frame. It is common to use steel materials as curtain plates, guide rails, seat plates, lintels, boxes, etc., and to use steel fire-proof roller blinds for door rolling machines and control boxes, and inorganic fiber materials as curtain surfaces (stainless steel wires or stainless steel wire ropes inside), steel materials as plywood, guide rails, seat plates, lintels, boxes, etc., and inorganic fiber composite fire-proof roller blinds for door rolling machines and control boxes.
Characteristics of fire shutter doors
1. Strong blocking ability: meet the requirements of fire stability and integrity, and effectively prevent the spread of fire.
2. Fast opening and closing: The integrated bus is used internally to make data transmission reliable and fast.
3. Simple operation: the setting of operation parameters is simple, convenient and accurate. It has the characteristics of giving priority to manual operation, and can be quickly lowered by manual mode even when the power supply is cut off, thus playing a fire prevention role.
4. High degree of intelligence: it has the functions of automatic phase sequence detection, correction and lack of phase protection, and the standby power supply of the main power supply can be automatically switched. It has the functions of smoking, temperature signal synchronization and step detection, and can distinguish and detect the fire in time, give an alarm and take relevant fire prevention measures.
