There are two types of controls for opening and closing an industrial door: manual and automatic.
A manual control system usually includes traction cables or chain hoists.Automatic doorshave an integrated electrical mechanism. Automatic control is carried out electrically using various systems: pull switch, key switch, code or key pad, radar, remote control, timer, magnetic card, etc. High-security automatic doors for collective use, using the various systems mentioned above, allow free or restricted access to secure areas.
The automatic opening of industrial doors can also be performed via a transmitter and receiver. This radio control system consists of a wireless transmitter and receiver to control the automatic opening and closing of flexible, sectional or metal curtain high-speed doors. There are several advantages: no cable installation, adaptation to all control boxes and cabinets, battery-free operation and it’s maintenance-free.
