The last couple of weeks when I set my alarm and exit through the garage door the sirens start to go off once the door shuts. Not every time but pretty often. Every time the door closes, the alarm makes a series of beeping noises. Maybe 4-5. I am not doing anything differently than I have in the past. I have tried unplugging it but it is still the same. I also keep getting tampering alerts when everything seems to be fine.
ok i see u have honeywell 5816 wireless door contact at the top of the sensor there should be a arrow pointing up right above it should be a little tab and u would need take flat screw driver or somthing push in on it and it should come off
just close it back if that dosent fix it only thing i can think of would be change the battery in it and maybe flip the door sensor around to wear the magnet is on the door and the bigger sensor part is on the frame only reason i say this is because with it on the door if it some reason get slammed shut or somthing like that it can shake the sensor around

it if ever does it again id replace the battery in it if im right it take the cr123A battery and also maybe flipping the sensor around from way it is mounted might fix it too but thats if it does it again
