Are locks on stair doors required to be hard-wired locks which unlock upon power failure?
I have seen this many times with mechanical lever trim for panic hardware, but I have never seen this...
I'm working on another whiteboard animation video to help explain the different code sections that apply to mag-locks. Did I forget anything?
For today's Fixed-it Friday photo, how about a little before-and-after action from Jimmy Resedean Jr. of A Better Door and Window Co.?
It made me wonder...with all of the hardware lovers and tech-savvy people who read iDigHardware, how many of you live in a "smart home"?
The access control hardware on your project is up and running (phew!), and then you are asked to provide evidence that every piece of electrified hardware on the job is listed to UL 294...
I found this photo on the Facebook page of Brendan Daley of Pasek Corp (who is not responsible for this "fix"). I am Wordless.
When I took the photo, the sensor did not unlock the electromagnetic lock until I actually touched the door and the movement of my hand triggered the sensor. It seems obvious that the sensor should not be positioned behind the exit sign (or any obstruction)...
I received this photo from Scott Aikenhead - Tech Support for Allegion Canada. I've never seen anything like this and all I can think of is that this contraption is dogging and undogging the panic hardware on a timer...
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?
With the recent adoption of NFPA 101-2012 by CMS, the annual inspection of fire door assemblies has become a top priority for many health care facilities...
Looking at the photos that accompany the article, the closing device is mounted in the door edge. Has anyone used this type of product?
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."
I spent a lot of time in airports today, and here are a few Wordless Wednesday observations...
This is one of the code issues I receive the most questions about, so it's the topic of my next Decoded column. Let me know if I didn't answer all of your questions. :)
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.
Steve Murray from Security Lock Distributors sent me these Wordless Wednesday photos...see any issues?
This is the perfect image to reinforce why it's so important to coordinate the electrified hardware / access control in advance. I have to admit - I learned this lesson the hard way...
Here's another of our latest group of whiteboard animation videos; this one covers electromechanical locking hardware like electric strikes, electric latch retraction panic hardware, electrified locksets, and electrified trim for panic hardware...
This Wordless Wednesday door is for a Florida public school's hurricane shelter. :(
For health care facilities, controlled egress can provide a greater level of safety for patients who require containment because of their clinical needs. This video explains the requirements for controlled egress and delayed egress...
When working with electrified hardware it's very important to understand the difference between fail secure and fail safe products. I hope this video helps!
I've received a lot of questions about stairwell reentry lately, so I think it's time for me to address that topic in another article for Doors & Hardware. In the meantime, here's a new whiteboard animation video about stairwell reentry!
I read an article this morning about a 3-year-old boy who eloped from his preschool in Bangor, Maine. The teacher saw him go through the exterior door...
There is some confusion surrounding the use of multiple delayed egress locks in a means of egress – in part because of variations between the codes...
Sometimes a system incorporating a sensor can be problematic, because traffic moving past the door can inadvertently unlock the mag-lock...
I could hardly believe my eyes when I received these photos from Kevin Wiley, a fire marshal. These doors are in a college dorm, and he said at first he didn't know why the door didn't close when he removed the wood wedge holding it open. Look closely...
I am SO EXCITED that the last class in the Decoded series is finally available on-demand, so you can take all 4 classes any time - for free!
According to Andy, this lock is on the exterior door of a school's bus garage. Inside the "bag" is a stack of large washers, and when it is attached to the lever it allows drivers to enter the garage without using the card reader. Even though it's Friday, I'm Wordless...
In case you haven't noticed, there is an interesting conversation happening on my post from earlier in the week about classroom barricade devices. If you have something informative to add in response to the manufacturers of these products...
I posted these photos (below) yesterday to ask what problems you all saw. Here's what I see...
I am assuming that the airport requested and received the proper code modifications for the pair of doors in the photos below - serving the airport terminal. Anybody know what the required code modifications would be?
See any problems here? Thanks to Tim Weller of Allegion for this Wordless Wednesday photo! The fun never ends!
While delayed egress locks must automatically unlock 15 seconds after a building occupant actuates the device, a controlled egress lock allows the egress doors serving certain areas to remain locked until they are unlocked by staff, the automatic fire protection system, or power failure...
Most stairwells in commercial and institutional buildings are designed to protect the means of egress using fire-resistant construction and fire door assemblies as opening protectives. When building occupants are within a stair enclosure during a fire...
Escape rooms are popping up all over the world, and have already opened in many US cities. The premise is that you are locked in a room with friends, family members, coworkers...
The possible solutions posted by iDH readers included electrified lever trim, electric latch retraction, delayed egress, a direct-hold electromagnetic lock, a networked wireless lock, or an electric strike. My preference would be...
This question comes up quite often, so I hope some of you have insight to share. In the words of my old friend Waller Elliott, "Picture this: You have an existing stairwell door (single), with a 90-minute fire rating..."
I guess this application would work if there wasn't a real need for security, but if someone is able to press the touchpad from outside the gate, they will be able to enter the secure area after waiting 15 seconds. It's a lot of money to spend for security that can be so easily defeated. I'll give them credit for installing the signage though!
Just when I think I've run out of questions and potential pitfalls, one shows up in my inbox. A while back I wrote an article for Doors & Hardware, addressing the required mounting height for operable hardware. The model codes and accessibility standards require operable hardware to be mounted between 34 inches and 48 inches above the floor. I noted in the article that some states have adopted different requirements for mounting heights...
Last week I got an email from an architect working on a renovation project at a college. Part of an existing classroom building is being converted into a new administration area, and the project scope includes preparation for an access control system that will be designed later. The electrified hardware was included in the current project, but the access control readers have not yet been added and the system is not powered up...
Yesterday someone asked me about the preferred lock function for a lactation room (aka mothers' room, lactorium), and I realized that I had not written about this before. Back when I needed a lactation room, one of my coworkers changed the passage set on my office to a privacy set...
Last week I received a really interesting question. The city of Sioux Falls, South Dakota, made a local code modification that requires certain stairwell doors to be automatic-closing. But what about security? This is the application I would use...
Some Fixed-it Friday photos result in mixed emotions - sadness that people resort to these methods, excitement that I have something to share with you that will make you shake your head, concern that the creative application could cause harm. Like these photos from Leo Lebovits of M&D Door & Hardware, taken at a public swimming pool...
The two common code questions that arise regarding UL 294 are - A) which electrified applications are subject to the listing requirements? and B) which components of a system are required to be listed?
Today's Fixed-it Friday photo was found on Imgur, so I don't know where it originated. It shows the creative use of an access control keypad to control egress. If this application was used in a memory care facility, it would be code-compliant if a delayed egress system or controlled egress system was used...
I know that much of the US is beyond swimming pool season, but this question just came up again so I'll leave it right here for you to find when you need it...
From the November issue of Doors & Hardware...the table below addresses the requirements for delayed egress and controlled egress, for both the IBC and NFPA 101. Do you know the difference?
We still do almost all of our shopping in the small tiendas and larger mercados, but last weekend I saw this door at la bodega. At first glance I saw the sign and thought it had a delayed egress lock...
