Re: Ademco Keypad not working after extended power outage

["Roland Moore" <roland@xxxxxxxxxxxx>]

Instructions from the Honeywell web site:

Set or Read the keypad address
·         The keypad address is set by holding the 1 and 3 keys together
immediately after powering up the keypad. The display will show you the
existing address. You may now key in the correct address. Press * to save
it.



Vista-10P/15P/20P

Set the first keypad to address 16, others may be 17-23

Each device must have a unique address



Verify that the address is enabled in programming.
Depending on the control panel that you have, you will enable the keypads
differently:

Vista-10P/15P/20P

Enable keypads 17-23 in program location *190-*196 for more information.



If there is still a problem:

Isolate the keypad
Try connecting the keypad directly to the panel with all other keypad data
wires removed and retest.
