EYEZ-ON

Q: Will this work with the older Vista 20se

I also had a Vista 20SE. The module would not work with it. I purchased a Vista 20P panel for $48, and made a terminal-screw for terminal-screw swap of the board, then re-programmed the board. Note: You have to reprogram the new board to match what was on the old one. So if you don't have your programming cheat-sheet, then you will need to cycle through all the settings on the old board, write them down, and then program them into the new board. And then you will need to make the necessary changes to support the EVL-4. Plan to spend the day doing it. Or two. Mine has been up and running for two years now.

Q: I bought a home with a DSC 1616 panel & RFK5564 keypad that was installed by ADT. I don't know the master codes. Can I still use this?

Installer code should either be 6321 or the last 4 of the previously used account number. If you cannot find out the last 4 ADT might tell you if you call and explain the situation. Otherwise like previous answers mentioned you would have to default the panel by placing a jumper between pgm1 and zn1, power up panel for 5 seconds than power back down and remove jumper. That will default the panel and will need to be programmed from scratch

Q: Can I use this module with tuxedo touch wifi keypads ?

If you have a tuxedo touch you are already able to connect to it through its built in web browser locally. Forward a single port on your router, set a local static ip to the tux and match that ip and port in your router. This way you'll be able to remote into the tux from anywhere and have full access of your alarm and automation. Updated firmware UV the tux will also give you email notifications.

Q: The 4 wires from evil to what pins on Honeywell 20P panel (pins 1 through 16)? Note that 20p pins have no colors name written.

Terminals are numbered from left, starting with #1. Black 4, red 5, green 6 and yellow 7. Same terminals as the key pad(s).
