Old 41A control, one zone, with shunt lock


ultrasonic

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.

That's a shorrock isn't it? Reminds me of the Model 45s

 

 

 

 

 

Yes I suspect the were from Shorrok, they were 41a shunt, 43a timer, 45 with zones etc

I was lucky enough to obtain a model 45 dating to the 1960s early 1970s. It was a shame it didn't work so I gutted it. Wish I didn't now as I probably could've gotten it to work again.
