if I had gone in there and seen that sweep generator I would have come back with a few screwdrivers and a willing friend to help remove it and help carry it out of there, like previously stated that is either an HP or possibly a Collins sweep generator used for checking the frequency of the transmitter. I'll bet lurking somewhere in that room was a nixie tube display frequency counter too! Gotta love old test equipment, they just don't build things like they used to.
Motts is right...this is the nurse call system master station. Calls from the room would be annunciated by a light in the top rectangle portion. The nurses could have a two-way conversation with the calling room using the controls at the bottom part. The dial would allow the nurse to call into the room directly.
This is an Edwards annunciator panel. There were 4 lights...A, B, C and D. If a switch was flipped in an area, it's corresponding light would come on and a buzzer sound would be heard at this station. The nurse could flip the switch on the station to silence the buzzer. When she responds to the call, she cancels the call in the room by flipping the switch off. This extinguishes the light on this panel and causes the buzzer to ring again. When she returns to the nurse station, she flips the switch on the front of the annunciator back to silence the buzzer, and the system is now ready for another call.
There are a lot of liars on here. A lot of lying, bored teenagers who want to pretend they know something. There are a lot of police and security. I have also heard stories about gang activity there, but that could be just another rumor.
I have been here a few times, At night also. Kind of a ghost hunting experiment. It was fun yet creepy. We heard some noises and voices. It was definately a good scare. Some lockets and hospital wriistbands were found. Dating a while ago. There are lots of paperwork and artifacts left here. We saw many shadows and heard many creaks and footsteps. Also we saw some doors close and my friend got locked in a room and couldnt get out. We finally got her out. This place I have to say definately has paranormal activities going on.
It's not all evil you know ;)
