I have an old ADT Vista 20p system and I recently installed the SEM for alarm.com. When I first installed the SEM, I neglected to enable the Keypad 8 Device address 23. I fixed this issue, and cycled the power to the system and it appears to work fine, except now my panel flashes “100 check” and beeps. When I enter the master code and press Off, the beeping stops, but the error message remains. How do I fix this?
Thanks.
Update:
It actually doesn’t appear my system is working completely. When I log into ADC it will correctly show the status of the alarm(armed/disarmed) and the status of each zone, but when I try to arm or disarm the alarm from the website it times out.
What, if any, of the SEM LEDs are lit up? These may flash in a sequence with pauses in between.
L2, L4, L5 and D4.
Thank you
Records indicate that the Master User Code did not sync properly. This is due to the original issue of failing to enable Keypad 8 Address 23.
In order to locally sync the Master User locally:
Enter the installer code.
Press [8] to enter user code programming.
Press [02] for the master code.
Enter a new unique four digit master code.
Test the master code to verify it is synced properly.
Thanks! This fixed the issue of not arming from the website, but the panel still displays the “100 check” error code. I have looked at the 20p manual, and it appears it is related to the RF receiver, but I am not sure how to fix it.
What devices are attached to the system?
How many keypads or RF receivers?
Are you using all wired sensors or wireless?
I cycled the power and the error code is gone, thanks again!
Excellent! Glad to hear it. Its likely the panel had not caught up to the fix (The SEM was on the system but not addressed correctly initially)
