Delayed Egress Locks in the Wild
I found the doors in today's photos on a recent trip to Indianapolis with my youngest daughter. Many of iDigHardware's long-time readers will remember her from the Olden Days.
WWYD? Fail Safe or Unlock Upon Loss of Power
As I mentioned a while back, Mark Kuhn of Allegion will be helping me out with some code development work and other duties, including an occasional blog post. In today's post, Mark shares some thoughts on a term found in the model codes.
Decoded: Controlled Egress Locks
This month’s question is a common one related to egress doors in memory care units. If you have a code question you’d like to see answered in my column, you can submit it by clicking the link in today's post.
USGNN: Quick Code Q+A
In my current column in USGlass Magazine, I addressed electromagnetic locks released by a switch in the door-mounted hardware. Do you know the difference between the requirements for this application vs. sensor-release locks?
USGNN: Quick Code Q+A
In my current column in USGlass Magazine, I addressed the requirements for electromagnetic locks released by a sensor. Are you aware of the change to the 2024 I-Codes affecting this application?
QQ: Product Certification to Codes and Standards
This Quick Question has come up quite often over the years - I was shocked to find that I had not yet answered it here: Is XYZ product certified as compliant with NFPA 101 (or any other model code)?
USGNN: Quick Code Q+A
In my current column in USGlass Magazine, I addressed the requirements for locks that delay egress for 15 seconds, which have become common in retail facilities. Do you know what is required for code-compliant delayed egress hardware?
WW: Health Care Corridor Door “Fix”
Last week I spent an afternoon touring a hospital under renovation after a large electrical fire (more to come on that), and I saw this modification that left me wordless. What do you think?
Specifying Zombie-Resistant Door Openings (Update!)
It's hard to believe that it has been 6 YEARS since I last updated this post on zombie-resistant door openings, and 9 YEARS sine I wrote the original version. With the new model codes coming out soon it's time for another update, and what better day to post it than on Halloween??
QQ: Fail Secure Electrified Hardware
Today's Quick Question is one that comes up frequently with Authorities Having Jurisdiction (AHJs): When fail secure electrified hardware is installed on an exit door, how is egress accomplished during a power failure?
Decoded: Fail Safe vs. Fail Secure – When and Where?
Because of some changes made in the 2024 editions of the I-Codes, I have updated this Decoded article addressing when to use fail secure vs. fail safe electrified hardware.
Egress Through Automatic Sliding Doors
Although there is a section in the I-Codes dedicated to automatic doors, this section does not address the hardware used for security and egress. Locks for automatic sliding doors are covered in other sections of the model codes.
WW: Wildfire Survival
Allegion's Inside Sales Team received these photos and the authorization to share them. This Schlage BE Series deadbolt was installed on a home that was destroyed by a wildfire in San Antonio, Texas. The lock survived. #wordless!
FF: Schlage AD993-IPB
For my Fixed-it Friday posts, I typically share photos of creative modifications - often applications that are not code-compliant. But I also like to share product changes that solve a problem. In today's post, a retrofit kit for the Schlage AD993.
QQ: Locking Interior Stairway Doors
Today's Quick Question about stairwell reentry has come up several times in recent weeks: Is it acceptable by code to install fail safe electrified locks on interior stairway doors in a 5- or 6-story building?
WW: Another Split Opening
Last week I posted a Fixed-it Friday photo of a 50/50 split opening that I saw in Valle de Bravo, and in response, Leo Lebovits of M&D Door & Hardware sent me today's Wordless Wednesday photo. I can see the resemblance!
Decoded: Special Locking Arrangements
Electrified hardware causes a lot of confusion regarding the applicable code requirements, but understanding one concept would help to clear up many of the misinterpretations: Is every opening with electrified hardware considered a "special locking arrangement"?
Battery back-up or no battery back-up? That is the question.
It's official! Since Mark Kuhn has achieved his EHC credential, I will be directing all questions on that topic to him! :) Today's post from Mark addresses the question of whether to supply battery back-up on access control doors.
Access Control Credential Migration
"If it ain't broke, don't fix it," is a phrase that I live by - mostly because I don't have time to deal with anything that isn't crucial to my existence. And if something does break, I just might find a work-around. But this strategy should not be applied to access control credentials.
WWYD? Interlocks + Delayed Egress
Yesterday in an airport I saw a bank of interlocks and an adjacent pair of doors with delayed egress locks. What do you think about this application? Do some AHJs require delayed egress doors where interlocks are installed? WWYD?
Follow-Up: Locked Stairwell Doors
Last week I answered a quick question about locking stairwell doors, and Jim Elder of Secured Design raised a great point in a comment on the post. Here is a follow-up related to the release of locked stairwell doors upon fire alarm activation.
QQ: Locked Stairwell Doors
Several people have asked the same Quick Question this week: Is it permissible by code for stairwell doors in schools to be locked during a lockdown? The answer is in today's post.
QQ: Fire Alarm Release of Electrified Locks
I have written about this topic from various angles, but this Quick Question keeps coming up: Is it code-compliant to have an electrified lock that is normally locked on the egress side, if it unlocks automatically upon fire alarm activation?
Coming Up: March Training
In March we will offer an AIA approved webinar and two Webinar Wednesday sessions. These are great opportunities for continuing your education without leaving your desk!
Locksmith Ledger: Five Code Considerations for Multifamily Residential Buildings
Many doors have to meet multiple sets of code requirements, for code-compliant egress, fire protection, and accessibility. There are dozens of applicable mandates that apply to door openings in a multifamily residential building; here are five to consider...
QQ: Special Locking Arrangements
Today's Quick Question came from an AHJ: When I am evaluating a door that is equipped with a special locking arrangement, do the model code requirements for normal locking arrangements also apply?
FF: Nothing to See Here
Logan Piburn of Dyron Murphy Architects sent today's Fixed-it Friday photos of an egress door modification. I can see a few problems here...how about you?
FF: DIY EPT?
Lee Frazier of Allegion sent me today's Fixed-it Friday photo, taken in a school. I have edited this post based on a reader's email telling me that this is not a DIY EPT, but a concealed power transfer. I have never seen this product in the wild, and I guess Lee had not seen it either!
December Training
As 2022 winds down (that was fast!), we have one more Webinar Wednesday with sessions on stairwell reentry and delayed egress requirements, along with a recently recorded Security in 30 presentation. Happy December!
Update! QQ: Mag-Lock / Panic Hardware Clarification
There is a change coming in the 2024 IBC related to doors that are required to have panic hardware and are also equipped with electromagnetic locks. I have updated the past post on this topic to include the change.
November Training
Don't worry...it's not actually November yet! But there's some training coming up next week that I don't want you to miss - including a couple of sessions that I'm presenting. I hope to see some of you there!
FF: At the Airport
People always send me photos with a note saying, "I saw this door and thought of you..." I LOVE getting those messages (who wouldn't?)! And last week when I was flying home from the BHMA meetings, I saw these doors and thought of YOU! :D
FAQs About Fail Safe and Fail Secure Hardware
One of the most fundamental requirements related to access control products can also be one of the most confusing - the functions of fail safe and fail secure electrified hardware. This post answers a few of the frequently asked questions related to this topic.
October Training
Where have the months gone?? It's October already! We have two Webinar Wednesdays this month, and the recording of my health care lunch and learn from last week will also be available soon.
FF: Hard Wired
Scott Tobias of arkaSpecs sent me today's Fixed-it Friday photos of a pair of automatic doors with electric latch retraction panic hardware. I don't claim to be an expert on wiring for electrified hardware, but this doesn't look right to me. :-|
Decoded: Requirements for Assembly Occupancies
My next Decoded column looks at how assembly occupancies are addressed in the model codes, as well as some of the assembly-specific requirements related to door openings. Let me know if I missed anything! :)
FF: I’ll just leave this right here.
What is happening in this Fixed-it Friday photo from Debbie White of Allegion? It's a restroom door in a gas station. I'll wait while you think about it.
September Training
It's my favorite time of the year - back to school! It's hard to believe that I have a college senior, and a high school junior and senior! But the learning doesn't end with graduation...we have plenty of continuing education available this month.
WW: Hotel Raceway
The fact that this stairwell fire door is now cracked in half helps to explain why drilling wire raceways in existing doors is typically treated as a field modification that must be approved in advance by the listing lab. I'm Wordless!
Decoded: Access Control Update
My next Decoded column addresses important code clarifications related to electrified hardware used in access control systems. I hope this article will help with more consistent interpretations of the requirements.
QQ: Rearming a Delayed Egress Lock
Quick Question: For delayed egress locks, the model codes require the activation of the 15-second timer to be an irreversible process. Is it acceptable for an authorized person with a key or credential to rearm the lock during the 15-second period?
Infographic: Delayed Egress or Controlled Egress?
The difference between delayed egress and controlled egress systems can be confusing...hopefully this new infographic will help. It explains how these systems work, where they are used, and how to choose the correct application.
UL 294 – Clarification
In yesterday's post I wrote about new text that was added to the 2021 IBC Commentary, clarifying the intent of the code regarding "normal locking arrangements." The requirements related to UL 294 listings have also been clarified.
2021 IBC Commentary on Egress Doors with Access Control
For years, I have been struggling with a common code interpretation related to electrified hardware, and I know that some of you have too. With the release of the 2021 IBC Commentary, this just got a lot easier.
New Page: Special Locking Arrangements
Electrified hardware can be particularly hard - especially when it comes to codes. To try to reduce the confusion that may result in inconsistent interpretations, I have created a new page called Special Locking Arrangements.
August Training
Today is my birthday and I will be spending the day flying to Minneapolis to work with the members of our Specwriter Apprentice Program and Sales Development Program. Meanwhile, back at the ranch, we have 2 Webinar Wednesdays this month!
FAQs About Electromagnetic Locks
While the installation of an electromagnetic lock can be relatively simple, the code requirements that apply to mag-locks are somewhat complicated and may be confusing. These answers to frequently asked questions should help.
July Training – Last-Minute Announcement!
Because of the holiday weekend and the Webinar Wednesday sessions scheduled for the first week of the month, this is a last-minute notification of the online training available TOMORROW - I hope some of you can make it!
QQ: Delayed Egress Mag-Locks
Last week I posted a photo that was submitted by Bruce Gill of North Central Supply as part of the 3,000-post celebration, and the photo raised a few Quick Questions about the mag-lock...
WW: 3-Point Locks + Delay
As we continue to celebrate the 3,000-post milestone, I don't know what to say about today's Wordless Wednesday photo sent by Bruce Gill of North Central Supply. SMH
