Customer: replied 1 year ago.
I am using a vista 20 p the question is can I use zone 1 and zone 2 from vista and wire it to the smoke zone and co zone in the interface unit without considering polarity of the zone? The interface unit has + and - and the vista panel zones are hi and low instead of plus and minus
Expert:  Michael Hannigan replied 12 months ago.

Hello. My name is***** can assist you with your question.

No, you cannot ignore the polarity. High is positive and low is negative.
