The rolling shutter door can be controlled independently and has manual function. It is linked with the temperature fuse device and directly linked with the fire control center control room. It can realize smoke sensing alarm and the rolling shutter door will automatically descend to the ground One point five - 1.8m Altitude, delay 180 seconds (adjustable) and then close in descent.
当下降时遇到障碍物可停止下降并上升; 可实现烟感报警一次下滑，温感报警二次下滑，且温感报警消除后可停止二次下滑，可在一个系统内互相转换。符合标准6.4.6的要求; 垂直启闭速度：不小于2m/min。其自重下降速度不应大于9.5m/s，平均噪音85dB。
In case of falling, it can stop falling and rising when encountering obstacles; it can realize one-time sliding of smoke alarm and two-time sliding of temperature alarm, and it can stop the two-time sliding after the temperature alarm is eliminated, which can be converted to each other in a system. Compliance with standards 6.4.6 Vertical opening and closing speed: not less than 2m / min. Its self weight falling speed shall not be greater than 9.5m/s The average noise is 85dB.
Before the installation and welding of stainless steel parts, the oil dirt, dust and other sundries on the surface must be carefully cleaned. Argon arc welding shall be used as far as possible during welding. If manual arc welding is adopted, small current welding shall be applied, and arc striking in non welding area is strictly prohibited. The ground wire used shall be in a proper position and connected firmly to avoid arc burn on the surface or excessive burn area; during welding, it shall take measures to prevent splashing.
Jinan roller shutter door manufacturer reminds you: after welding, when cleaning welding slag, stainless steel flat shovel shall be used instead of carbon steel flat shovel. The weld joint shall be carefully polished to make the smooth transition between the weld joint and the base metal surface, and there shall be no slag, air hole, undercut, spatter, crack, incomplete fusion and other quality defects.
