Re: Relocating a Radionics D1252 keypad (8112 panel)

[Jim Rojas <jrojas@xxxxxxxxxxxx>]

This is not a problem. But since it is an older 8112, I don't suggest
you power down the panel at all. This system uses SRAM to store the
programming data. If the lithium cell is dead, your panel will display
CALL FOR SERVICE...which means you are screwed.

1. Remove the keypad wiring at the panel on at a time.
2. Relocate and reuse the keypad wiring harness.
3. Hook the keypad back to the panel. Connect common (black), data wires
(green & yellow), and then power (red) in that order.
4. If the keypad fails to display anything, first check your
connections. If everything looks ok, place a 1 second short across
keypad COM terminal and the communicator disable terminal. If I remember
correctly, the communicator disable terminal is marked on the front. It
should be the top right screw terminal.
