LED indication over long run.

[firemonkey]

200m is quite a long run, just an idea that I've done similar before is to use the fire alarm system to pass the signal.

 

 

It does depend a lot on the system, but many will let you have a supervisory signal that doesn't show on the panel etc but allows an interface at the roller shutter to be connected to a sensor of some kind, and then switch another interface at the other end to light up the LED. If its Apollo then you could just put the interface somewhere can be seen, then when it operates the output - the LED on the interface will come on so you can stick a dymo label on it accordingly
