An automatic door system usually goes unnoticed until it suddenly fails. caesar door You can make a hundred trips through the front of a grocery store without a thought for the mechanism. But on the hundred-and-first occasion, when the door seems to be making a point of ignoring you and just standing there, all of a sudden people have questions.
It’s Physics, Not Sorcery
You might think there is some kind of intelligence at work determining who is allowed in. There isn’t. Microwave or infrared sensors detect movement or presence, relays that to a motor and you are done with it. A shopping cart and a human set it off in precisely the same manner. Which explains why a stray pigeon will put the door in motion while someone loitering too far to the side is left out in the cold. The sensor has no way of knowing your intent; it only responds to the areas it has been programmed to monitor.
If those detection zones are poorly positioned the door may open unnecessarily, wasting energy, or fail to detect visitors during busy periods, causing delays.
Choose Your Mechanism Wisely
Different automatic door systems are designed for different applications. Retail stores commonly use sliding doors to maximize usable space. Medical facilities tend to go with swinging doors for the better seal and accessibility. Folding doors are ideal where installation space is limited. But every one has its Achilles heel. Sliding doors can become obstructed by dirt or debris, the hinges on a swinger will eventually give way under strain, while folding doors may lose alignment after prolonged use. Put the wrong type in the wrong building and the maintenance bill will mount in no time.
What Happens During a Power Outage
Building owners are often caught unawares by this: what does the door do in a blackout? Safety regulations generally require automatic doors to fail safely so that in an emergency one can open it by hand and get out. If it locks up solid, that is more than an inconvenience, it is a liability. A qualified installer should explain the fail-safe operation before completing the installation, including any backup power options.
The Tedium of Maintenance
Lubricating tracks and recalibrating sensors is about as much fun as it sounds. However, neglecting maintenance for a year can result in noisy or sluggish operation. It is a small thing, yet in high-traffic buildings, even small delays can create noticeable congestion. Quarterly inspections are an inexpensive way to reduce the risk of costly repairs.
More Than a Convenience
Automatic doors are essential for people using wheelchairs, pushing strollers, or carrying heavy items. They provide convenient and independent access. Modern building codes establish accessibility standards, from clear width to opening force. Ignoring these standards can prevent people from accessing buildings they have every right to enter. There is nothing fancy about good design in this regard. You simply do the math on who is using the door and build for them.
