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...
I need your help! And for the first 10 people who find a mistake that nobody else has found, I'll send you a $25 Amazon.com gift card by email (limit - one gift card per person).
This Fixed-it Friday photo illustrates the common problem of an access control system that has been modified for convenience. No matter how much time and money are invested in planning and installing a system, human intervention is always a factor...
Delayed egress vs. controlled egress...can you explain the difference? Do you know when and where each type of locking hardware is allowed, and what the IBC requires in order to ensure life safety?
I often find that I am more cautious about modifying code requirements than even the AHJ. This opening is serving an Assembly occupancy, where delayed egress is not allowed by the IBC. In addition, the AHJ approved the 30-second delay instead of 15 seconds...
I have nothing to say except "thank you to Grah Security for today's Wordless Wednesday photo."
I checked with the ICC and NFPA for a code opinion, and both staff members acknowledged that the code does not address this specific issue, so it would be left up to the AHJ. One made a good point - the time to initiate the timer and the time to release the device should be two separate periods...
Jeff Payton of Williams Electronics sent today's Wordless Wednesday photo. I'm the first to admit that I'm not an expert on exit signs. If you ARE an expert on exit signs, can you explain the need for the high-level sign? If only the door closer installer had taken as much pride in the installation as the conduit installer. :)
What's wrong with this Fixed-it Friday photo, sent in by David Seeley 0f Clark Security Products?
Securing cooler doors with access control products is likely to become a more common application as facilities become increasingly automated. Without an access control system it's tough to control what is taken once the door is opened (like the coin-operated newspaper vending machines). Have any of you seen a system that works well to secure cooler doors and interface with a system like the one pictured here, where supplies are ordered online and then picked up from the cooler?
I know that some of you will be able to help with this question from a contractor, who has all-glass doors with direct-hold magnets making noise when the doors close and when the mag-locks engage...
Today's post was delayed because of a computer glitch, but I want to make sure the notification reaches my subscribers asap in case any of you want to participate in this upcoming webinar offered by Allegion - AIA continuing education credit is available. Sorry for the late-night notification!
This photo may be one of my favorite Fixed-it Friday photos ever. It was sent to me by Michael Carney of Allegion. This application is in place on the roof door and all of the fire escape access doors in a dormitory high-rise. A very creative way to install an exit alarm, but I don't know how secure or how durable it is...
The Schlage® NDE Series wireless lock with ENGAGE technology has been selected as a finalist in the Architizer A+ Awards in the Hardware category! The winner is determined by the product that gets the most votes...you can vote here until April 3rd!
There was an important change to the 2015 International Building Code (IBC) that could help to reduce the occurrence of child abduction from hospitals. Many maternity wards have infant abduction systems that use a sensor to activate a delayed egress lock when a baby is taken near the exit. But for some facilities, delayed egress locks may not be enough...
Today's Fixed-it Friday photo from an anonymous friend is a classic example of the coordination problems that can so easily arise when doors, frame, and hardware from multiple vendors arrive on the job-site...
There is one more online class in the series of four that I'm teaching on behalf of the Door & Hardware Institute - this Wednesday, February 18th, 11 a.m.-12:30 p.m. Eastern. I'll be covering the code requirements pertaining to electrified hardware...
There are 7 basic code categories for electrified hardware used to control access or egress, and this edition of Decoded provides a brief refresher on each as well as some recent code changes. Many of these code applications, but not all, fall into the category commonly called “special locking arrangements.”
My next online Decoded class will be held on Wednesday, January 21st from 11 a.m.-12:30 p.m. Eastern. This is the third class in the series of 4 presented on behalf of the Door & Hardware Institute, and I will cover the requirements for life safety and egress...
Today's Wordless Wednesday photos were sent by Jim McDonald of Twin City Hardware (who is not responsible for this installation!)...
