Hi - I'm ripping out a builder-installed Honeywell system and installing an Elk M1 Gold. Window sensors work fine. However, the front door (which is clearly labeled, and WORKED on the Honeywell system, I made him do a walk test with me) uses a 4-wire connector, and the installer who put in the Honeywell system mentioned it was wired as a "fire". I should have asked more questions of him, but didn't.
So the 4 wires coming from the front door WERE connected on the Honeywell system to:
Black: Aux Power Input -
Red: Aux Power Input +
White: Zone 1 Hi
Green: Zone 1 Lo
Two questions:
1) Why would a door sensor be wired like that?
2) I assume that implies I should use the +SAUX/NEG pair for black-red and the zone (probably 16, since it's nearby the SAUX port) for white-green on the Elk M1?
Thanks so much for your help!
