How do I wire to a Honeywell Vista 20 panel?

Post by louboe »

The instructions with my Envisalink3 merely say put the red to the red slot etc. On my panel there are a number of connections none have a color named to them. Is this something I can do myself? I am not an installer.

The wires from the EnvisaLink3 connect to the Ademco keypad bus. The colors match the following connection screws on the Vista 20 terminal strip.

4 Black Ground
5 Red +12 volts
6 Green Data from keypad (Envisalink3)
7 Yellow Data to keypad (Envisalink3)

If you look at the connection diagram (in the installation manual or as a sticker on the back of the door to the metal box the panel is in), this should all be much clearer.
