I realize this may be more appropriate in a security installation forum (can anyone recommend a good one with lots of traffic/posts?), but since a lot of people here use the GE Concord 4 system I thought Id try my hand here. I just had my Concord 4 system installed and we are having some problems, #2 being the most annoying: 1) Touchpanel shows Bus Failure 0 and Bus Failure AM3 when I press the '*' key. The Bus Failure AM3 Im pretty sure is just because we have not yet connected anything to the unit and will probably resolve when connected to control4. I have no idea what the Bus Failure 0 is nor how to fix it, any suggestions? 2) Our system touchpanel AND Siren both go off whenever system state changes and for all status beeps. For example when entering or exiting with a delay both will go off every few seconds until the system is armed/disarmed. This is really annoying, I mean I could handle having the touchpanel do that but I cannot deal with the siren going off every 2 seconds for 2 minutes or whatever. Plus, if it is nighttime and I come home when my wife has the system armed to 'Stay' then it will go off until I get inside and disarm the panel, probably waking her and the neighbors up. Ive read the installation manual and the userguide and I cannot figure out how to get it not to do this. I know when arming you can use '5' before entering the codes to do a silent arm, but that still doesnt solve the entry problem since you cant get to a touchpanel before opening the garage, etc. I really need help here, this is driving all of us nuts and the person that installed it doesnt seem to know the answer either. Anyone else with Concord 4 panels having these issues, or is your system always silent unless the alarm is tripped?
