I knew this great starter panel as a 41A control used / installed in the 1970s, Smart metal box, with hinged lid to conceal unit, 12v external power supply, one cct, plus shunt cct. Indicators, Green Clear, Red Fault (key locked by a solenoid) Yellow Call engineer to reset if auto Dialer fitted. Bell test removed power from SAB to sound external bell. Yale key switch.

Does anyone recall in the 70s going into the police stations control rooms to work on the original direct lines to the police, seem to recall a large unit taking 10-20 modules, with red, green, amber lights on,, red for alarm, amber for line fault and green  for clear, along with a toggle switch to silence buzzer.

This was a private wire provided by BT direct from the police station to the protected premises.

Be great to see any photos if you have any

no,

 

however I went with the scouts to a police station visit in 1980's aged 10 or thereabouts

 

highlights where all the cool knifes handed in under an amnesty & learning the police could unwind after a hard day of forging paper ect... in their very own bar located on an upper floor.
