I have a client with a rather large HAI Omni ProII system where the keypads will not turn off.
Yes, they are set to timed, all have unique console addresses and the system has been defaulted several times.
I have disconnected the panel from the network to rule out any weird networking issues and the problem still persists.
I sent the board out to HAI for repair and they sent me back another board even though they stated nothing was wrong with the old board. On the old board it failed the HAI diode test so that was the reason it was sent in. In addition to failing the diode test on the console bus I was getting phantom events on the keypads. The system would attempt to arm itself or just randomly start beeping and display "unit number xx". My next step is to disconnect the consoles and card readers and then reconnect one by one. Has anyone ever seen anything like this?
