Decoded: Touchless Solutions for Healthy Environments
My next Decoded column for Door Security + Safety Magazine addresses the code considerations for facilities where changes are being made in order to limit the spread of germs.
QQ: ISA on Actuators
Today's Quick Question: Are actuators for automatic operators required to have the International Symbol of Accessibility (ISA)?
Codes to Know: Automatic Doors
With the current focus on how to limit the spread of germs, many facility managers are considering the addition of automatic operators so doors can be operated "hands-free."
Actuator Follow-Up
Last week I posted some Fixed-it Friday photos showing auto-operator actuators, and I just received some interesting follow-up photos from Paul Stockert of EYP Architecture & Engineering. What do you think?
QQ: Auto Operator Timing
What are the required opening speed, closing speed, and hold-open time for a low-energy automatic operator? What about a vestibule situation with sequential operation?
WWYD? Standby Power for Auto Operators
How do you provide the required standby power for an automatic operator if there isn't building-wide backup power? WWYD?
QQ: Vision Lights in Automatic Doors
Does the vision light height requirement apply to automatic doors as well as manually-operated doors?
Decoded: Signage for Automatic Doors
My next article for Door Security + Safety Magazine addresses the signage required for automatic doors. It will appear in the April edition.
WW: Moose & Squirrel
Animals + automatic doors...what could be better on a Wordless Wednesday? Ok - I can think of a few things that might be better, but check these out anyway...
Decoded: Potential Automatic Operator Changes (January 2019)
We could soon see a code change that would require automatic operators for public entrances. Here's the current status.
WWYD? Auto Operator App
I recently came across an app that literally "opens doors" for people who have disabilities that make it difficult or impossible to initiate an automatic door by pushing an actuator.
FF: Don’t let the door hit ya…
While this may seem like a great idea at first glance - a wireless actuator mounted on the door to open the door automatically - this does not meet the recommended guidelines for actuator location.
Restroom Kits for Automatic Operators
Questions continue to arise regarding how to properly specify/supply hardware for a single restroom door with an automatic operator. The challenge is that the outside actuator (push button) for the automatic operator has to be interfaced with the locking system; otherwise, the actuator could open the door even when the restroom is occupied.
Decoded: New Requirements For Pedestrian Automatic Door Operators and Sensors
This article addresses an important change to the BHMA standards for automatic doors operated by a motion sensor or control mat...
QQ: Opening force for automatic doors
The codes and standards limit the opening force for interior, non-fire-rated, manually-operated doors to 5 pounds, hence the question...
QQ: Push ‘N Go For Automatic Operators
In yesterday's post, I wrote about power-assist operators to clarify that these are not the same as low-energy automatic operators. This 2-part question arose from a misconception that "power-assist" is the same thing as "Push 'N Go."
QQ: What is a power-assist operator?
This is Part 1 of a 2-part question, so check tomorrow's post for Part 2. First, I'd like to clarify what defines a power-assist operator...
FF: Public Restroom
I'm in Guatemala! I'm on the hunt for some beautiful and/or interesting Guatemalan doors to share with you, but until then, here are some doors from a recent trip to Phoenix...
LCN Automatic Operators (video)
Even though automatic operators have been available from LCN for longer than I can remember, I still get questions about which one to use where, why to choose one over the other, and pneumatic vs. electric operation...
QQ: Do the accessibility standards require automatic operators?
Are automatic operators required by the ADA Standards and ICC A117.1 - the predominate accessibility standards used in the US?
WWYD? Health Care Pair
The doors have some obvious damage caused by carts contacting the push side face, and carts hitting the door edge when it's open. So...WWYD?
WW: Good Luck
I received today's Wordless Wednesday photo along with the following explanation..."On a service call to find out why doors will not lock and had to follow the wires to the inspirational message left by the last technician in header."
WWYD? Arched Door – Auto Operator
The proposed solution for an auto operator on an arched door is shown below the photo, but I'm wondering if there are more aesthetically-pleasing options. WWYD?
FF: Auto Operator Coordination
If an automatic operator is properly coordinated so the latch is released when the actuator is pressed, only the signage required by the BHMA standard should be needed. This is an accident waiting to happen.
Signage for Low Energy Automatic Doors
Deputy Jeff Tock of Allegion sent me this photo, showing some confusing signage on an automatic door (push to operate an outswinging door?) - which reminded me that it's been years since I've written about the signage requirements for low-energy automatic doors...
Fixed Non-Contact Switches
If a low-energy operator is actuated by a motion sensor, it has to meet the requirements of A156.10 instead of A156.19, which usually means the door must have guide rails and safety sensors. What about the "wave-to-open" switches...are these considered motion sensors?
Intro to Low-Energy Automatic Operators (video)
Do you have questions about low-energy automatic operators or the standards that apply to them? Maybe this will help...
FF: Which Came First?
Sort of like the chicken and the egg, this Fixed-it Friday photo from Steve Turner and Ray Valentine of Precision Doors & Hardware made me wonder...was the closer added because the automatic operator wasn't closing the door properly, or was the automatic operator added because the closer required too much opening force? Or one or the other stopped working completely but was not removed?
Reader Photos
It's been a really long time since I posted a collection of reader photos because I've been using a lot of these submissions for Wordless Wednesday and Fixed-it Friday. Here are some of the reader photos that have been patiently waiting in my inbox...
FF: Lego Automatic Door Operator
I was a Lego Robotics coach last year, and we barely got our robot to knock down the cups in the maze. This Fixed-it Friday video of a Lego Mindstorm automatic door operator is impressive...
WWYD? Stairwell Pressure
When you have a pressurized stairwell that is required for smoke control, the increased pressure in the stairwell makes doors swinging into the stair more difficult to open, and doors swinging out of the stair may not close and latch. WWYD?
6 Accessibility Changes to Watch Out For (November 2014)
The 2010 Americans with Disabilities Act (ADA) Standards for Accessible Design went into effect in March of 2012, but there are several requirements that continue to surprise architects and specifiers as well as door and hardware suppliers. These issues can be costly to resolve if they’re discovered after the doors and hardware are on-site, so it’s important to stay current on the requirements...
FF: My Door Won’t Close
Thank you to Tim Meegan of Doors Incorporated for today's Fixed-it Friday photo! It's a classic! In case anyone is wondering, this article talks about the mounting guidelines for auto operator actuators!
Understanding New Accessibility Requirements for Doors

FF: Smart Birds Open Doors
This video is pretty amazing. Swallows nesting in a university parking garage could have been locked in when doors were added to convert the garage to the campus bike center. Is this an example of the swallows' intelligence, or dumb luck?...
Music City Center – Nashville, Tennessee
I know what you're thinking..."When is she going to stop talking about Nashville and get on to something interesting like gasketing or clear opening width?" :D
Changes to A156.19 – 2013
A couple of months ago I wrote an article for Doors & Hardware, which appears in the September issue. As always, I triple-checked my sources, and confirmed that 2007 was the most current edition of A156.19 - American National Standard For Power Assist and Low Energy Power Operated Doors. Well, today a notification regarding the brand new 2013 edition showed up in my inbox! Luckily, there are not a lot of changes that would impact the article.

Reader Photos
Here's the latest batch of reader photos...don't forget to send me any interesting doors you see on your summer vacations!
Actuator Protector
Here's another interesting application that I saw at Foxwoods. These plastic covers were on all of the automatic operator actuators in the conference center.
Force = Mass x Acceleration
Since it's one hour until Friday and I've had a very long week trying to catch up from being on vacation, here's some door-humor (yes, really). It's an automatic door on the Columbia University Physics building. The auto operator was being replaced with an LCN Senior Swing, but the installers were struggling through the installation without a wiring diagram, which can be extremely tough if there's other hardware involved. I feel a site visit coming on.
Middle School Entrance
Last night I went to a presentation at one of our 3 local middle schools, which I'm guessing was built in the 70's. What struck me right away was that the exterior doors are all about 10' tall, and the interiors are about 9' with a transom panel above. What a strange application for a school. They still seem to be working pretty well though.
Falcon 8200 Series Auto Operator
It seems like I should know all about myself now that I'm in my (early!) 40's, but I recently learned that the way I learn best is from a live demonstration or a video. As soon as I start trying to read about something, my mind is off in a hundred directions, but put the same information in a video and I'm right there.
Automatic Operator Actuators
The 2007 edition of ANSI/BHMA A156.19 - American National Standard for Power Assist and Low Energy Power Operated Doors requires low energy operators to be initiated by a "knowing act", which is described as "consciously initiating the powered opening of a low-energy door using acceptable methods, including: wall- or jamb-mounted contact switches such as push plates; fixed non-contact switches; the action of manual opening (pushing or pulling) a door; and controlled access devices such as keypads, card readers, and key switches."
Door Opening Force
Door opening force is the measurement of how many pounds of force are required to open a door. The requirements for door opening force are found in the Americans with Disabilities Act Accessibility Guidelines (ADAAG), ICC/ANSI A117.1 Standard on Accessible and Usable Buildings and Facilities, and the Massachusetts Architectural Access Board requirements (521 CMR).
