We have designed many systems with exactly the feature you are describing. I typically specify an Elk Voice Module, Elk Interior Speaker, and a Bosch DS150 Motion Detector.
Thanks. This has got to be a record reply! Did it work for your client? Is it installed in a situation where they had problems before? If so, did it reduce or resolve the problem? Here is one I found that is self contained.

Also just recently used this arrangement in a bleach plant. Employees passing from the office area to manufacturing area are reminded to put on safety equipment (protective glasses, earplugs, etc.) as they approach the door to enter.

I have done this in the past as an integrator, with nearly the same bits that Mr. Silva uses.
The application: Areas where Delayed Egress is not allowed by the AHJ. The door may have to be unlocked and free by code, but you can hook up voice annunciation and loudspeaker and bring attention to it regardless:
You can use the USB uploading connector and upload custom messages to that Elk Annunciator. I used this free 'Text to Voice' site, but there countless others.

Brian, that's a a nice narrative and drawing.
In the cases where the system was installed as a pre-warning to an emergency exit alarm on the floor below, we installed the motion detector on the stair landing above rather than at the door itself. This provides advance warning to people as they are heading down the stairs, hopefully causing them to turn around before they even get close to the door.
