Indicator Deadbolt

Falcon D271

I know I just mentioned bathroom door hardware yesterday so maybe this will be the start of another series.  🙂

Almost every week someone asks me about the use of deadbolts on bathroom doors, often because they want to use an indicator deadbolt, like the Falcon D271 (right).  I saw an application recently at Harvard, so the last time I went in for a meeting I waited until the coast was clear and whipped out my camera.

In my opinion, using a deadbolt on a door with push/pull hardware is code-compliant.  There may be facilities where you shouldn’t give the public control over locking a door (ie. a multi-stall school bathroom), but the door in the photos is a single bathroom in an administration building.

There’s no egress problem here because it requires one motion to release the latch (turning the thumbturn).  There isn’t an accessibility issue because the thumbturn can be operated with one hand and without grasping, tight pinching, or twisting of the wrist.  This isn’t a fire-rated door, which would require positive latching, and it’s obviously not an occupancy that would require panic hardware.  If there was an existing latchset, adding the indicator deadbolt would be an additional motion required for egress, so that would create a code issue on most occupancy types.

And an item of interest to be filed under the “green building” category (or possibly the “TMI” category), these flushing instructions were posted in the bathroom.

    The IBC requires one motion to unlatch the door, not one motion to get the door open.

    Hi Lori!
    I admit I was one of those who’s approached you in the past. I hate to disagree with you, but in my opinion, if you add an indicator bolt to an inswing door with a push-pull, it would require two seperate motions to egress the room. One to retract the bolt and one to pull the door open. You don’t have this same issue with an outswing door, beacuse you could actually retract the bolt and push the door open almost simultaneously. I used to see it differently, until I specified it on a project and a supplier pointed it out. After discussions with the Owner and Architect, we had to remove it.
    The only way I found around the single motion issue is with a Schlage L9486 mortise privacy set. I also use a 9496 w/occupied indicator for single Faculty Toilets, doors that are always kept locked, but need additional privacy for controlling accidental opening of the door by another authorized user.
    I feel myself going “Geek”, so I’ll cut it short. Sorry.
