I’ve got a few more devices but more should be on the way - hopefully.
fixed the youtube url for you
How do you do it?
simple you click the youtube box between the tfp and thumb then the numbers that i have bolded.

then you put the numbers and letters inside the youtube code
From now on, let’s just have the mods/admins or the OP fix the embed code so we don’t have a bunch of duplicate posts with the same video on them. 
Probably the best thing to do.
ok sorry.
I think the extra pair of wires on the Edwards pull station is so one pair can be from the previous device or panel, and the extra pair can be to the next device or EOL. The BG8 is like that.
That’s probably what it’s for.
Nice collection you have so far! I hope that you get some electromechanical horns soon.
