1. The type of smoke exhaust should be in accordance with the design. In addition to assume a smoke exhaust system can be partitioned, with ordinary open air outlets, the exhaust port shall be normally closed and have remote control on the remote control + metal tuyere.
2, manual opening device should be installed in an obvious position, and there are fire signs。
3. The smoke exhaust port actuator is installed in place and the effective air intake area of the smoke exhaust port meets the design requirements.
4, smoke exhaust port installation position must be installed at high altitude, at least away from the ground should not be less than 1.8 meters.
5, check whether the setting of the smoke prevention zone, whether the enclosure meets the requirements, whether the smoke discharge port is installed in the corresponding smoke prevention area, and consistent with the design position (location change, it is possible to protect the distance is greater than 30 meters)。
1, tuyere type should be consistent with the design. Room air in addition to assume 2 layers within the positive pressure air supply system can be used in ordinary open wind estuary, the rest are normally closed and should be used with the remote control on the remote control + metal tuyere. The air supply in the stairwell usually adopts the self opening air inlet and so on.
The open state is consistent with the design of 2, check the air (usually air remote control are to be in closed state)。
3 、 the installation of the actuator is in place and does not affect the effective ventilation area of the air outlet.
4, check manual open device, hand no obvious position, and easy to open.
