Relocating a Radionics D1252 keypad (8112 panel)

[Tom]

I have an old 8112 panel with a D1252 keypad attached to the front of
the enclosure that the 8112 is located in. I would like to move the
keypad about 20' away from the 8112. Are there any issues with moving
the keypad? Any special requirements for the wire? Will replacing my
original keypad with a new one require any programming changes?

Thanks.

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.

I take that back...put a jumper across COM & the disable/restart
terminals. This will put the panel to sleep. Then move the keypad. Once
you are done, remove the jumper and all should be ok. Keep in mind that
the panel may send a signal to the monitoring company.

if it does send anything it'll just send a processor restart - restore F
usually...and I doubt anyone would do anything about that kind of sig.
