The "Bank" ones are for access control.

Basically one door had to be locked before another can be opened.

And in a robbery the doors "Interlock" and trap the armed gunman............................clever or NOT.

Banks used as hostage indication.

To stop been taken hostage by burglars waiting for staff when opening.

Staff used a remote fob to power the lights to say its safe to enter.

 

Low risk areas such as cupboards,upstairs etc would have a detector fitted and programmed for hostage.

Hostage zones only tripped the light and not the alarm.

Hostage system would set with main system

In morning staff would arrive outside and press the fob.

Green = all ok, enter

yellow = 1 zone tripped, caution with staff staying outside while someone enters.

red = two or more zones tripped, enter only with police.

 

Burglars used to break-in and wait for staff in cupboards etc until they opened.

 

Remember local tsb when builders working late and they tripped the hostage zones while working.

next day staff had police check it out. good call out that day

Errrr not at the local HSBC is it like that.   Lights tell when the door can be opened.

Nor the Barclays.  Lights tell when door can be opened.

Nat West is just a auto door.  What lights.
