FCI MS-2 Question

I own a FCI MS-2 pull station and I was wondering: which terminal is positive and which is negative? I have tried looking it up but no luck.

A pull station is just a switch - there is no positive or negative terminal. One wire in and one wire out, and you should be good.

The switch just makes or breaks the circuit. There is nothing else going on which would require polarity to be considered.

Thanks for telling me. I know the Fire Lite BG-12s have specific terminals for the switch.

On a standard BG-12, it doesn’t really matter either. I know they use red and black wires, but at the end of the day a switch is just a switch.
