Hi everyone, I'm new to this forum but desperately need your help. I have an optima 2 plus house alarm. The pie cable to the garage has been problematic and the cable outside weathered. I always omit this zone but simply want it permanently disconnected. I have opened the main white box and fully removed the pir wired to my garage. The zone for this is now flashing and I cant turn my alarm back on to use. How do I completely tell the system that this zone no longer exists. Any help Would be realy appreciated.
