Emergency Doors

[Timbo]

Hi Paul,
The last one I did, I had to open from the inside by manipulation. Once opened the staff did'nt want to know the combination but locked off the dial in the unlocked position When I told them this door was therefore not secure, I was told "thats o.k. theres a grille gate on the inside".
As if this is as secure as a proper vault door with 2 com locks on !!!! Takes all sorts I suppose.

First of all thank you for reviving this interesting thread.

Some large institutions would have a main door, controlled by combinations, and the an emergency door with keylocks. Certainly those emergency doors were very rarely opened. The ones I saw all had day gates.

The idea of using the emergency door for ventilation was, and probably still is, very common in the middle east.

One image I saw early on in the thread is that Chubb one with the TDR door and the guy in front of it. The door is 6' tall so that man can't be 3' tall. I know they used to use small people to photograph against products to make the product look larger than it actually was, but that engraving, or whatever the term is, is ridiculous.

(My mother claimed to have known a man whose job it was to make specially small furniture for show houses on estates. Whether the story was true, I don't know).
