As traditional markets for locksmiths shrink and disappear, other markets have opened, and automatic door operators is one of them. Automatic door operators are one of the more interesting architectural hardware items for locksmiths to install and service.
Strong demand for “handicapped accessible doors” has increased as the population ages and businesses seek to avoid a rise of lawsuits from injuries that occur when people enter or exit buildings.
Door-operator technology continues to improve, the range of products has expanded, and prices are lower. All of this makes automatic door operators a far more feasible proposition for a growing number of applications.
Open to All
It’s a business advantage to create an environment that accommodates everyone.
The Americans with Disabilities Act (ADA) played an important role in introducing the concept of making entrances more accommodating to individuals who have a disability. In addition to meeting the needs of the 54 million Americans who have disabilities, however, a building that complies with ADA also is accessible to the elderly, children and people who carry and move materials and equipment.
The American Association of Automatic Door Manufacturers (AAADM) is a trade association that’s involved with automatic door openers. Among the services and resources that the association provides:
- Training for and certification of installers
- Information to end users and architects
- An inspection checklist that can be used to determine whether a door operator has been installed properly or is in proper working order.
The AAADM also has a listing of certified dealers and inspectors on its website, www.aaadm.com, to help individuals to find qualified professionals who can supply or install door operators.
After I became AAADM-certified, my employer got many calls from national facility-maintenance companies that wanted support for their client’s premises and individual companies that wanted to install an operator and sought a qualified local vendor.
Three types of automatic swing-door operators are in the market: low energy, high energy and power assisted.
High-energy operators are used in commercial applications, such as a supermarket. These operators require auxiliary sensors, because the door operators have the power to move the door fast enough to possibly injure pedestrians, particularly young children, the elderly or the disabled. High-energy door operators also frequently require guard rails and presence sensors.
Low-energy door operators are the typical retrofit sale for the locksmith. They’re self-contained and require switches that pedestrians press (a “knowing act”) to actuate the operator and open the door.
For most applications, low-energy door operators can be installed without auxiliary sensors or safety equipment and be code-compliant. This is because the low-energy operator has integral sensors and is designed to stop when the door encounters an obstacle while in motion.
However, after you’ve spent enough time in the field, you’ll realize that some individuals don’t have to come into contact with a door for an injury to occur. So, including auxiliary sensors around a low-energy operator is a great way to provide a custom-designed system to your customer.
A large selection of sensors and actuators is available to the installer. You should be familiar with the standards to which automatic door operators are manufactured, installed and adjusted:
ANSI/BHMA A156.19 – Power Assist & Low Energy Power Operated Doors
ANSI/BHMA A156.10 – Power Operated Pedestrian Doors, the standard that applies to full-power door operators.
A roundup of possible products:
BEA LZR-FLATSCAN SW
BEA’s LZR-FLATSCAN SW is a laser-based time-of-flight presence sensor for use as a stand-alone safety sensor on full-energy automatic pedestrian swing doors. This solution also can be used as a reactivation sensor on the approach side of low-energy doors.
The product’s technology generates 170 detection points across a single curtain, which allows the LZR-FLATSCAN SW to cover the entire face of a single door leaf, including the hinge area. Its Finger Detection Technology uses 100 detection points within the hinge area of the door to protect hands and fingers while the door is in motion. And a leading-edge safety feature extends the detection area beyond the leading edge of the door for enhanced safety.
The LZR-FLATSCAN SW exceeds the ANSI 156.10 section 8.2.2.3 standard for detection area and meets section 8.1.4 for monitoring.
Its laser technology ensures independence of all types of flooring (pedi-mats, carpet, reflective flooring, wet surfaces, etc.) and the surrounding environment of the door (guide rails, walls, weather).
The LZR-FLATSCAN SW has a hubless system and fewer components for easier setup and installation, and its Hand Gesture Setup technology reduces configuration time.
Note: This sensor is powered by DC voltage only. If only VAC power is available, a 12-volt transformer paired with a rectifier must be used. A 24-volt transformer and rectifier will damage the product.

BEA LZR-MICROSCAN T
BEA’s LZR-MICROSCAN T is a laser-based sensor system designed for automatic swing doors. It uses time-of-Flight technology to eliminate the limitations of infrared-based devices. The system’s background independence eliminates nuisance detections caused by changing weather and floor conditions, while gyroscopes sense the movement of the door for accurate positioning.
The LZR-MICROSCAN T provides adjustable pattern depths that exceed the ANSI 156.10 8.2.2.3 standard and provides 100 percent coverage in all door states (fully open, fully closed, opening and closing). Its combination of high-resolution, self-adapting detection zones coupled with reduced uncovered zones create an accurate and reliable safety sensor.
The LZR-MICROSCAN T has built-in troubleshooting through an on-board error log, which ensures easy technical support, and its plug-and-play technology that uses a central hub and intuitive LCD interface reduces installation and setup time.
