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!)...
Most magnetic holders provide 20-30 pounds of holding force, and can be released manually by pulling on the door to separate the door-mounted armature from the wall-mounted magnet. The signage here tells me that the magnet is probably not anchored to the wall properly, and I guess adding a sign is one way to fix the problem...
In January of this year, I wrote about a tragic fire at a senior home in L'Isle Verte, Quebec, in which 32 of the home's residents were killed. The inquest into this incident is currently underway, and I've been keeping an ear to the ground to see if there are any lessons to share...
I know it's Fixed-it Friday, but I'm Wordless. Maybe you can help? Caption this...
I'm at the NFPA School Safety Summit this week and it has been an amazing opportunity to hear from code officials, first responders, and other experts, and to break into smaller groups to discuss school safety issues and the necessary code changes. I'll definitely have more to report on this later.
Today is the second webinar in the series for access control integrators, so here is my second list of Quick-Tips (the first list can be downloaded here). There have been some changes in the 2015 edition of the IBC, so it's worth a review...
I don't know about you, but once a product number takes root in my head I have a tough time getting used to a new one. I've still got numbers in there from the 80's! But it's time to do a memory upgrade because the Schlage L9080-EL and L9080-EU locksets have been replaced with a series of new and improved electrified mortise locks...
Allegion is conducting a series of monthly webinars for access control integrators, which address code compliant access solutions for various applications. All webinars are held at 2 p.m. Eastern. Click here to register or to access recordings of past webinars in this series...
Paul Goldense of Goldense Building Products took today's Wordless Wednesday photo while searching for the problem causing mag-locks in a psychiatric unit to work intermittently. I think he found the issue...
Recently a question from a code official landed in my inbox - "Can an electric strike on a fire door be operated by a motion sensor?" For example, if a door was often used by people carrying boxes or other large items, could a sensor release the strike so the building occupants could just push on the door rather than turning the lever to exit?
On a thru-wire hinge, the wires are typically run through the thickness of the hinge leaf. Like inside of the hinge leaf where you can't see them. Not actually through the hinge. Oh never mind. You're doing it wrong.
All I can say about these photos of a field-prepped electric strike is...this is why we specify all of the hardware, including access-control hardware, in the hardware specification. Field preps do happen on occasion, but not all installers are created equal...
In a recent discussion about code change proposals, there was a question about whether electromagnetic locks should be an acceptable alternative to panic hardware, on doors serving Assembly occupancies - essentially the application shown in the photos below. If approved, a door serving an assembly space, and perhaps even Educational occupancies depending on how the proposal was written, could have mag-locks released by a sensor, and no panic hardware - no latching device at all...
In preparation for an upcoming class for access control professionals, I'm putting together some printable summaries of code tips on security-related topics. The first sheet I'm working on addresses requirements specific to fire door assemblies that would be important to an access control integrator or security consultant...
Something recently caught me by surprise and I feel like I should bring it to light so that anyone who is specifying, supplying, or installing electrified hardware on stairwell doors would be aware of the potential issue...
Even if we only consider the space with the smallest occupant load - the classroom, the codes do not give us many options for preventing a student from eloping. If the classroom has an exterior door that is required for egress, it can not be locked in the direction of egress....
