Automatic Sliding Doors

How Automatic Sliding Doors Work

An automatic sliding door is a doorway with electronically operated panels that glide horizontally on a track, opening and closing automatically. They are a common sight in commercial buildings, offices, and even some residential settings.  These doors offer convenience, accessibility, and a modern aesthetic.

Here’s a breakdown of how they work and their key components:

Components:

• Door Panels : These are the visible parts of the door that slide open and closed. They can be made from various materials like tempered glass, metal, or plastic, depending on desired functionality and aesthetics.
• Automatic Door Opener : This is the motor that drives the door’s movement. It’s typically a linear motor, hidden within the header (top) box of the door system.
• Control System : The “brain” of the automatic door. It receives signals from sensors and triggers the opener to operate the door. The control system can be programmed for opening speed, dwell time (length of time the door stays open), and activation methods.
• Sensors : These detect activity near the door and send a signal to the control system to initiate opening. There can be several types:
  • Motion Sensors : Detect movement using infrared (heat) technology or microwave technology. These are often located above the doorway.
  • Pressure Sensors : Embedded in the floor mat, these activate when weight is applied, triggering the door to open.
  • Push Button Sensors : Provide manual activation for entry or exit (often used for handicap accessible doors).
• Safety Features : These are crucial to prevent accidents:
  • Safety Beam : An invisible beam that detects if someone or something is in the doorway, preventing the door from closing. This beam is usually located near the floor on either side of the doorway.
  • Safety Edge : A sensor strip along the closing edge of the door that detects contact and reverses the door’s direction.

How They Work:

1. Activation : When a person approaches the door, they trigger a sensor (motion, pressure pad, or push button).
2. Signal Sent : The sensor sends a signal to the control system.
3. Door Opens : The control system activates the motor, which drives the door panels to slide open on the track.
4. Dwell Time : The door remains open for a programmed dwell time to allow people to enter or exit.
5. Closing : Once no movement is detected within the doorway for a set period (dwell time expires), the control system sends a signal to the motor again.
6. Safety Check : Before closing, the safety beam and edge sensors ensure no one or nothing is in the doorway.
7. Door Closes : If the safety check is clear, the motor drives the panels to slide shut again.

This cycle repeats continuously, providing a smooth and convenient automated entry experience.

The Benefits of Installing Sliding Doors

Automatic sliding doors offer a wealth of advantages for businesses and even some residential settings.  Here’s why you should consider installing them:

Effortless Entry and Improved Traffic Flow:

• Convenience: Welcome customers and employees with a hands-free experience, ideal for busy entrances.
• Increased Efficiency: Sliding doors open smoothly, allowing for a constant flow of people without bottlenecks.

Modern Appeal and Space Optimization:

• Sleek Design: Enhance your building’s aesthetics with a modern and sophisticated look.
• Space-Saving: Sliding doors require minimal clearance when opening, maximizing usable space in your entryway.

Accessibility and Security:

• Universal Access: Sliding doors are easier to navigate for people with disabilities or carrying packages.
• Seamless Integration: They can be integrated with security systems for access control and added peace of mind.

Additional Advantages:

• Energy Efficiency: Consider low-energy options to reduce heating and cooling costs, especially in high-traffic areas.
• Reduced Noise: Sliding doors can help minimize noise transmission between the interior and exterior of your building.
• Low Maintenance: Modern automatic sliding doors are built for durability and require minimal maintenance.

By installing automatic sliding doors, you can create a welcoming and convenient entry experience for everyone,  enhance the look of your building,  and potentially improve energy efficiency and security.
