I'm reinstalling my Optima intruder alarm system. I powered it down, moved it then powered it back up with the remote LCD keypad like I normally do. It always seemed to work fine until now it keeps on saying that it's got a Tamper Lockout Fault on the screen. I've tried all the suggestions that I've found but they do not seem to work. Any ideas????

..... not without standing in front of the panel with a multi-meter and checking the tamper circuit(s) and for shorts between the tamper and alarm circuits etc etc
