Technical performance of automatic rolling shutter doors:
Automatic rolling shutter door is a new type of Shenzhen automatic rolling shutter door developed by our factory based on market demand and the special situation of vertical shaft fire separation. This product has changed the transmission system of the original vertical rolling shutter and achieved horizontal fire separation of the vertical shaft, replacing the combination of several fire-resistant vertical rolling shutters. This not only solves the space utilization problem of fire separation for vertical shafts, but also reduces the overall project cost.
Technical performance:
1. Fire resistance limit greater than 3 hours
2. The wind pressure resistance capability meets the requirements of GB14102-93
3 zui Thermal radiation intensity
4. Smoke leakage rate: less than 0.2m3/mm under a pressure difference of 20Pa
5. The wind pressure resistance strength meets the requirements of GB14102-93.
6. Opening and closing method:
(1) Manual: Use a hand cranked mechanism to control the opening and closing of the roller blind.
(2) Electric: The opening and closing of the roller blind is controlled by a button switch, which can be used to stop the horizontal roller blind at any position.
(3) The horizontal roller shutter is equipped with a limit switch, which can automatically stop when it is fully opened and closed.
(4) A horizontal roller shutter used for evacuation corridors, exits, and automatic control shall be equipped with a delayed closing control device 1.5 meters before the curtain surface is fully closed.
At present, there are many products with unqualified strength, which seriously affects the use of PVC quick rolling shutter doors in Shenzhen. The structure of the rolling shutter shaft mainly refers to the depth and structure of the shaft heads at both ends of the rolling shutter shaft inserted into the steel pipe. The depth of the shaft head plug should be about 1/10 of the shaft length, and there should be two flanges and sufficient welds. Some manufacturers' products are stuffed very short, even using a flange, and there is a risk of breakage after using these shoddy doors for a period of time.Under normal circumstances, large buildings are equipped with a central fire control system in accordance with the provisions of the National Fire Protection Law. When a fire occurs, the smoke sensor installed on the roof (referred to as the smoke sensor) first receives the smoke signal and alarms the central control system. The fire central control system identifies and connects the power supply of the Shenzhen automatic rolling shutter door in the area where the fire alarm is located, causing the fireproof rolling shutter in the fire area to descend at a certain speed. When the rolling shutter descends to a position about 1.5 meters above the ground, stop descending to facilitate the evacuation and evacuation of personnel. The Shenzhen automatic rolling shutter door stays in the middle for a certain period of time before continuing to descend until it closes. The downward speed and intermediate dwell time of Shenzhen automatic rolling shutter doors can be adjusted during installation.
