This sign – and the fire door it’s attached to – are definitely left over from the Olden Days. There was a time when fire doors were closed manually to protect the building when it was unoccupied. Nowadays, fire doors have to close and latch the door at all times. Automatic-closing devices allow doors to be held open for convenience, but automatically closed during a fire to compartmentalize the building. The motivation for this change may have been some tragic fires in occupied buildings that resulted in high numbers of casualties. Today’s fire doors have saved countless lives.

Typically those level sliding & incline sliding fire doors were attached with a fusible link and weighted cable system to close them during a fire. Good for saving property but not so good for saving lives. As I recall the fusible links were rated to melt at 120 or 160 degrees, useless when the building is full of smoke before the flames reach the opening.
Exactly! Thanks Tony!

We still have a few of those.
Things get interesting when the custodians take off the counterweights and the door closes like a freight train.
They could do a lot of damage to someone in the way.
