Ji'nan electric door operation terminal has three buttons, shutter doors respectively and one line, and a public line, this line will relay control button to open the door and the public line to access controller end NO and COM. This allows you to open the automatic door with swipe control. In general, the electric door has three function buttons, that is, open the door, pause, close the door. The following by the Ji'nan electric rolling shutter door manufacturers Xiaobian for you to introduce the electric rolling shutter door, remote operation failure, what are the reasons?
1, transmit power: transmit power is large, distance, but the power consumption is large, prone to interference
2 、 receiver sensitivity: receiver sensitivity increased, remote control increased, but easily disturbed, causing misoperation or uncontrolled
3: Antenna: using linear antennas, and parallel to each other, remote control distance, but occupy large space, in use, the antenna elongated and straightened, you can increase the remote control distance
4 height: the higher the antenna, the farther away the remote control, but limited by the objective conditions
5, stop: wireless remote control the use of the provisions of the state UHF band, its propagation characteristics and optical approximation, linear propagation, diffraction is small, such as walls will be greatly discounted remote distance between the transmitter and the receiver, if the reinforced concrete walls, due to absorption of wave conductor.
