As Gatechs Automatic Doors Company is one of the largest and oldest suppliers of automatic doors in Egypt, it has gained extensive experience in this field. If you are interested in learning how automatic doors work, continue reading this guide to understand the basic details.
Basics of Automatic Doors
Automatic doors consist of a set of components and motors that work together as an integrated system. These systems include safety mechanisms to prevent injuries or damage, in addition to mechanisms designed to facilitate the opening and closing process. Each part of the system functions in harmony to ensure smooth and safe operation.“The efficiency of automatic doors depends on the integration of operation, control, and safety systems to guarantee reliable performance and complete user safety.”Automatic Door System Experts
Automatic Door Opening and Closing Systems
The most common way to open and close automatic doors is by using a transmitter or remote control. This device is usually small, portable, and contains several buttons, corresponding to the number of channels or systems that can be operated. When a button is pressed, a signal is sent to a receiver connected to the motor control unit. Popular frequencies used include 433 MHz and 868 MHz. The frequency and type of encoding (such as fixed code or rolling code) must match between the transmitter and receiver for the system to work correctly. Once the signal is received, the motor executes the command to open or close the door depending on its current state.Access Control for Automatic Doors
Access control systems offer multiple ways to open doors, such as an external button that triggers an alert inside, followed by pressing an internal button to allow entry. Intercom systems with audio and video capabilities can also be used to enable the owner to communicate with and see visitors before granting access. Some systems support wireless technologies such as radio or Wi-Fi, while others use mobile networks, allowing doors to be operated from anywhere with a compatible signal. Security can be enhanced using keypads that require a programmed code, card readers, or fingerprint systems.How Automatic Gate Motors Work
Motor control units receive signals from remote controls, intercoms, or keypads and convert them into mechanical motion. The system may include a single motor for sliding doors or two motors for larger systems. Some systems use electric motors, while others rely on hydraulic systems. In sliding doors, the door moves along a track mounted on the ground using wheels and is driven by a gear that meshes with a rack attached to the door, moving it open or closed. Hinged arms, hydraulic pistons, or underground motors may also be used for certain types.Safety Methods for Automatic Doors
Safety is a key element in automatic door systems. It can be achieved by preventing access to hazardous areas, such as using nets or barriers to block fingers or limbs from gaps. Electronic safety measures include infrared photocells, which operate in pairs to send an invisible beam; if the beam is interrupted, the door immediately stops. Rubber safety edges can also be installed on door fronts, which stop and reverse direction upon contact with any object.- Remote control systems with compatible frequencies and encoding.
- Multiple access control options via audio, video, or codes.
- Electric or hydraulic motors depending on the door type.
- Advanced safety systems such as photocells and safety edges.
