Warning: A whole week of false alarms nearly cost me a big account

Last Tuesday I finished a new build install for a dentist office in Austin. Looked clean on the walkthrough, left happy. Then the calls started Wednesday morning at 3 AM. Dust from the drywall guys set off the motion sensors twice that day. Then the cleaning crew set off a door contact Friday night. The office manager called me Saturday pissed off saying they might pull the contract if it happened again. I spent Monday reprogramming zones and swapping out two sensors to lower sensitivity. Has anyone else dealt with new construction dust causing false triggers this bad?

Man that sucks, but check this - did you test the voltage drop on those sensors during peak AC hours? New construction HVAC can pull enough juice to make cheaper sensors act flaky.

Oh boy, that's a good catch. I bet most folks overlook that with all the new high-efficiency units running.

I had the same issue with a church install in 2018, dust was a nightmare the first month.
