If you own, or live in a multifamily or commercial building, you presumably always look for methods to improve your assets. For residents, visitors, and building employees, automatic doors improve safety, boost convenience, and provide a smooth, hands-free entering experience.
A sensor is necessary for automatic doors to know when to open. The door operating mechanism receives a signal from the sensor when it recognizes a signal. The system then opens the door after receiving that signal.
Three of the most typical varieties of automated door sensors are as follows:
1. Pressure sensors
Pressure sensors, which were first used in the 1960s, use changes in weight or pressure to determine when the door needs to be opened. On the ground, pressure sensors are typically mounted as mats or pads. The pressure sensor senses a change in pressure (the person’s weight) when they approach the entrance and step on the mat, which causes the door to open.
2. Motion detection and optical sensors
The majority of automatic doors today use motion sensors to operate. The majority of motion detectors track movement using passive infrared (PIR) or microwave pulses.
Microwave beam motion detectors emit microwave pulses that are used to track moving objects’ reflections. On the other hand, passive infrared sensors use temperature variations to identify body heat.Sensors that use microwave technology are typically more expensive as they can cover a broader area than infrared sensors. However, they are susceptible to electrical interference.
3. Access control or video intercom system
Through an access control or video intercom system, the automatic door system can also determine when to open and close.The door opens in response to a signal from an access control system rather than being alerted by motion or pressure. Any device that has been configured with the access control system, whether a keycard, a fob, a smartphone, or other device, may transmit that signal. Automatic doors controlled by cloud-based access control systems or smart video intercoms are suitable for multifamily buildings and commercial establishments that need to only allow authorized persons admission. For both fire and safety laws, the majority of multi-family and commercial buildings require an access control system or video intercom. Additionally, smart video intercoms and access control systems enhance the resident experience.
How does a sensor operate to open the door?
The door opening mechanism receives a signal from the sensor after it has determined that someone needs to enter the building. Depending on the type of door you have, an electric motor powers the door opening mechanism, which opens the door.
Types of automatic doors <h2>
- Automatic sliding doors – these can be installed with tracks and rollers or hung from overhead rails, making them perfect for two-way traffic.
- Automatic swinging doors- these can be opened inward or outward, making them perfect for one-way traffic.
- Automatic folding doors – these doors fold up onto themselves to create a tunnel, making them perfect for narrow entries when space is an issue.
- Automatic revolving doors- these doors allow for both exit and entry at the same time, making them ideal for crowded areas.
<h2> Benefits of automatic doors for buildings <h2>
- Energy savings: automatic doors can help maintain conditioned air and thereby reduce the heating and cooling costs of your building.
- Touchless entry: no one needs to touch common elements like door handles when using an automatic entrance. This reduces the likelihood of germs spreading.
- Convenience: people are always grateful for the ease of hands-free building access, especially while carrying heavy furniture, handling children, or carrying big grocery bags.
