[GreenKeys] Model 15 Bell

[DR HOUSE]

I think you guys are correct.  Many times the machines were in places
where they were not continuously monitored.  Obviously a newspaper
or radio station would not want the incoming open loop to go unnoticed.

I also think that a momentary break in the line signal would ring the  
bell.
When I get my M20 KSR wired up I will let you know.

The base and typing unit were AP but the keyboard was UPI.

More on that shortly...

Question on the Model 15 AP machines:

Recently, my AP news loop from Heavy Metal opened and the machine ran
"open".  When it runs open, it also continuously rings the bell.

Rice has a Model 15 AP machine too and his does the same thing on open  
loop.
Question....did AP rig these machines to ring the bell as an alarm  
when the
loop opens?  That's Rice's suggestion and it makes sense.

Any input is appreciated.
