Data Center Security
The latest post from Mark Kuhn addresses a type of facility that is becoming much more common these days - data centers. How do you think the model codes should address these buildings?
What’s that? Coordinator Bracket
The other day Mark Kuhn asked if I had done a "What's that?" post about coordinator brackets...coincidentally I had just taken some photos of one while we were at the BHMA meeting in Phoenix!
Fail Secure Electric Strikes and Fire Alarms
Mark Kuhn's latest post addresses an issue that I wrote about a while back...it's been 10 years since my original post, so I guess it's time to take a fresh look. :D
Seeking a Code Modification
In the latest post from Mark Kuhn he answers the question: "Why do you teach about codes that we haven’t adopted yet?" The situation described in the post is a great example of why.
Old Buildings, New Assembly Occupancies
Mark Kuhn and I are in Golden, Colorado this week, doing some training for our Early Careers Program. Mark's latest post looks at a common problem with assembly occupancies...
Panic Hardware Styles – Push Pad vs. Crossbar
Mark Kuhn's latest post looks at the advantages of push pad style panic hardware vs. crossbar style. Can you think of any other advantages or disadvantages to add?
Wide doors and panics don’t mix.
In Mark Kuhn's next post, he writes about a problem many hardware specifiers have faced...a conflict between door width and the code requirements for panic hardware.
Indicators – When, where, and why?
In his latest post, Mark Kuhn explores lock status indicators...where are they required by code, and when are they just a good idea? Where do YOU specify or supply indicators?
If it were easy, they’d call it EASYware!
The funny thing about writing a hardware specification is - EVERYONE has their own way of specifying hardware for a door opening. The even crazier thing is - most of those ways are CORRECT!
Retail Access and Egress Control
Today's post from Mark Kuhn addresses an interesting application that I hadn't thought about before - a combination of electrified hardware and a key-operated lock on the same door.
Courtyard Egress Questions
In today's post, Mark Kuhn asks an important question about securing courtyards: How do the 2021 IBC requirements affect these doors when there is an access control system?
WWYD? Locking Stairwell Doors
When a stairwell door unlocks (or is always unlocked) to allow building occupants to leave the stairwell if it becomes compromised during a fire, what happens next? WWYD?
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.
“Tis the season to decorate your doors….BUT WAIT!”
Mark Kuhn's latest post is a great reminder about holiday decorating and the considerations for fire doors and other doors in a means of egress. Happy Holidays!
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.
“Yes, I overspecify panic hardware, but let me tell you why…”
In Mark Kuhn's latest post, he makes a compelling argument for specifying panic hardware in some locations where it is not technically required by code. Do you agree with Mark's reasoning?
WW: “Cooler” Security Solution
Mark was minding his own business at a family get-together in a local events venue (with an occupant load of >100 people), and there was a door calling his name from the back of the room. You can see why in today's Wordless Wednesday photos. :D
Funeral Home Code Compliance
As I mentioned last week, you will begin to see some new faces around here. Mark Kuhn of Allegion will be helping me out with some code development work and other duties, including an occasional blog post - like today's post about a frequent source of code violations.
