re: ADT Salesman

We've had ADT for over 20 years since the house in middle of nowhere was 1st broken into about a week after grandmother moved into assisted living.

They've lived up to their end of the contract without fail. Alarm goes off and they call the numbers we list with them. If they do not reach us/our local contact person up the road, they will notify sheriff. Sheriff then responds to check it out.

We've had 3 false alarms. Latest was right before that vicious cold snap. The hallway motion sensor tripped. (1 other false was 15 years ago same sensor) After reading up on how the motion sensors work, I'm pretty sure it was some kind of temperature bubble that either the on or off of the central hvac triggered (warm/cold air bubble either caught in draft against bedroom ceiling/above door space until heater turned off again or some such, and then the bubble passed in front of sensor, the temp differential triggered it). Since no other sensors triggered, especially points of entry, we knew it was a false alarm.

The other false alarm may not have been so false. Back door sensor had to be replaced as it somehow got misaligned in the middle afternoon of a bright sunny day while was at work 45 miles away. I suspect someone tried to kick in the door but no way to prove it as only the sensor was disturbed significantly. (after the original break-in the rear door was beefed up significantly)

They've also sent replacement backup batteries twice, no charge. They offered assistance if needed to change the battery for me but it's just a red and back plug connector and unscrewing a couple screws for the panel cover.
