[GreenKeys] Another Whats-it ???

[Don Robert House]

You got it Doug
If you turn the image of Whatsit 4 you can see that the contact is  
shown in an idle state. The way the cam is coded it would be turning  
counterclockwise and so the code would be 2123.
This unit looks as if it can be automatic or having been wound the  
code could be send manually by pushing the black button.

Just guessing, but I would say it's perhaps part of something like an  
alarm system, where the mechanism is wound up and then released by  
activating the solenoid coil inside.  There appears to be a pulsing  
cam on the top of the works that would pulse 2123 or 3212, depending  
on which way it rotated.  Some fire alarm systems have sending units  
like this where the alarm system, if triggered by a smoke head or pull  
box or whatever, would send a voltage to the solenoid which then  
starts the clock-wound mechanism that outpulses the box code for that  
location.

Again, I don't know for sure with your unit there, it's just an  
educated guess.

Good luck, hopefully someone else may know something more concrete.
