Fuzzy Credentials

A sales representative was in a customer’s office recently with our 34K Series Standalone lock. The customer was reviewing the brochure when he noted one of the additional features was a “fuzzy credential entry available” and asked what it was.

It’s a good question and the answer may help dispell the image that just popped into your head from hearing the term fuzzy credential.

Introduced in 1965 by Lotfi Zadeh with the proposal of the “fuzzy set theory,” it is a form of “Many-valued logic in which the truth values of variables may be any real number between 0 and 1. It is employed to handle the concept of partial truth, where the truth value may range between completely true and completely false.” ¹

For our standalone 34K Series this means if the lock is in the fuzzy mode it allows a user to enter a random string of numbers that includes the user’s complete access code. This code will grant access as if the user entered just their given access code.

The next logical question is why someone would enter a string of random numbers that includes their code, versus just entering their code to access entry?  If you’re escorting a visitor through the building, you may want to use the fuzzy mode in order to conceal your personal entry code. This will save you from having to change the code to maintain security.  Or, if your entry door with the 34K Series is next to a public area, it would be safer to use the fuzzy code as it is difficult for people to remember a long string of numbers.

The next time you hear the term fuzzy credentials you’ll know what it means!

If you have any questions on our 34K Series standalone lock, fuzzy credentials, or any of our products please don’t hesitate to give us a call at 800-255-3590.

The Next Generation

The gifted class from the Central Christian School visited Hager headquarters a few weeks ago. They were learning about the engineering profession and the different types of engineer specialties. A daughter of our COO, Josh Hager, is in the class and he offered to have the students visit Hager and hear from our engineers what they do.

Mark McRae, our Director of Engineering, and Daniel Sprehe, a Product Engineer, spoke with the students about the engineering process a product takes, from conception to manufacturing.  They spoke about how once a design has been approved a prototype is created along with the amount of testing it takes before a product is ready to be sold. They also shared the difference between a mechanical and electronic engineer and how they work together.

School Security and Safety since Columbine

18 years ago the Columbine school shooting shook the world with images of students filing out of school buildings in single file with hands raised, SWAT teams surrounding the school, and the stark terror on the faces of the students and teachers. For the security and safety community, it renewed efforts to keep our most cherished citizens safe.

School security has increased tremendously since the Columbine tragedy. A direct result was the introduction of the classroom security function. In order to secure a traditional classroom function lock, a person had to step out into the hallway from the classroom and use a key to secure the door opening. With the introduction of the classroom security function, the lock is able to be secured from the interior of the room.

Access Control: Door Hardware and Code Compliance by Brian Clarke DHT, AHC, CDT, CSI

This article was published in the DHI, Door Security + Safety Magazine in January 2018 issue

Keeping occupants safe is a common goal for facility managers and property owners. As the number of break-ins, active shooter incidents and other violent encounters continue to grow, controlling who enters a building has become more vital than ever before.

For healthcare, education and office buildings, standard door and key configurations do not always provide the type of security necessary. This is leading decision-makers to look at more sophisticated access control solutions. The electronic access control market has become more refined in recent years and it is important to know what is available and what may fit the needs of a given facility. Furthermore, the type of hardware chosen must be code-compliant, making proper selection even more important.

In high use buildings, such as a school or office building, access control must allow for a door opening to have free means of egress, during an emergency, along with fire protection and meet accessibility requirements. The International Building Code (IBC) defines an accessible means of egress as a “continued and unobstructed way of egress travel from any point in a building or facility that provides an accessible route to an area of refuge, a horizontal exit or a public way.”

UCLA Lockdown

Yesterday there was a lock down on the UCLA campus in the Engineering 4 building. With the use of social media word spread quickly and students definitely took the alert the school sent out seriously.

Several students posted photos on social media showing how they were barricading themselves in rooms including rooms where the doors had no locking devices.  It is difficult to determine from the photos if the rooms are specifically classrooms or not.

UCLA_June_1_2016_P3No indication if the door had locking
hardware on it and this was for reinforcement

UCLA_June_1_2016_P2@Jasonschechter states “doors open outward
and aren’t able to be locked.” Can’t tell from photo if
device is a passage function, classroom function
or if the lock wasn’t operational. If classroom function
the students were smart not to open the door to
lock from exterior side.

UCLA_June_1_2016_P1This room looks like it could be a classroom.
@whydaphnewhy is stating the “doors open outward, no locks.”

Classroom Barricade Devices

We had another post planned but felt this was more important to share.

This video has surfaced on Facebook. It currently has 3,552,279 views, 122,560 shares, 21,189 likes and 1,153 comments.  These are the type of devices that those of us in the hardware industry are fighting against.

From the comments it is evident that people don’t understand the dangers these devices can contribute too. If you have a moment we encourage you to comment on the Facebook post to help education the general population.

Here are links to additional information as to why barricade devices are not a good choice.

Classroom Barricade Devices and why focusing on them makes us vulnerable to threats

Expert says many of these products are not code compliant and could nullify the warrantees of locks and door hardware.
