I installed two new window wireless sensors and glass break sensors on zone 1 (hardwired). Everything seemed to ok until the first night when I could n't disarm the panel after the Automatic Stay Mode kicked in over the night . The only way to reset was to power down then disarm it with the user cod e during start-up. I never had this problem before. Everything else works fine. I deleted the schedule, powered down, left it alone a few days then tried to re-enable the schedule again during the day just to test it out. Same thing happened as before. Very strange. Any ideas? Thanks!
