Access-Controlled Egress Doors

I’m in San Antonio, Texas at a beautiful hotel and conference center for our annual sales meeting, and there are A LOT of doors with mag-locks.  Check out the coordination of the bank of pairs below…concealed closers, overhead stops, and mag-locks all coexisting in the same space.  Notice that the mag-locks have a split armature to save space vs. a double-magnet.  Every pair has a motion sensor, a push button, and a key switch, presumably for locking and unlocking the mag-lock.  I would not typically specify a separate key switch for each opening in a bank of doors, but nobody asked me.

And while we’re on the subject of mag-locks, how about another quiz question?  You can enter the monthly drawing every time I post a new question and the drawing registration doesn’t give me your quiz results, so go for it!

The ceiling above one of the sets of escalators has gorgeous art glass hanging from it.  Feast your eyes…

    Do you have a link to an example of what you think this would look like?

    I was thinking an electric stirke, but that is just to get in.

    The only other thing I can think of is an electronic touch bar?

      Hi Charles –

      If you mean what a door-mounted release for an electromagnetically locked egress door would look like, there are 3 options that I can think of at this time of the night. 1) a latchset/lockset with a request-to-exit switch (looks like a regular lockset), 2) panic hardware with an RX switch (looks like regular panic hardware), or 3) a bar that senses touch (http://epub.securitytechnologies.com/eacc/201110#pg266).

    Lori,

    I was the Hardware Consultant on this one (JW Marriott, San Antonio). The Serpentine Bars on these openings and also touch release (as required by the AHJ in addition to the other requirements) and are also “Blow-open” doors as well. There was a lot going on here but on the first (and subsequent) tests they worked without a hitch.

    There are about 107 each openings similar to these around the property. Not all were Blow-open but all set up for emergency release.

    It was fun!

    Lori, do you know what brand and model number mag lock this is? Thanks!

    I would like permission to use a couple of your photos in my code training. Please let me know if that is permitted.

    Key switch still has the Sargent 6300 Construction core installed. Now I know why I only received back 99 cores out of the hundred I supplied.
