Safewatch 3000 alarm system Sensor CHECK

Our alarm system is going off and our control panel tells us to CHECK location #22. After checking #22, there is no indication that anything is wrong. Alarm system is reset. No issues. Then about 8 hours later, same thing happens except the location number changes. After investigating the new location and again finding nothing wrong. Alarm sysyem is reset.

Why is the alarm system going off?

Sometimes this happens with wireless transmitters. How old are the transmitter batteries (those lithium batteries are good for 3-5 years, depending on how heavily that door/window/motion is activated)?

Has their been a change in the RF environment? A new wireless router, or the relocation of an existing one, or even something as small as hanging a large mirror on the opposite side of the wall from the location of the wireless receiver can cause wireless to not make the check in window.

We purchase the home in 2013, believe the alarm system was installed in 2000 or 2001. We replaced all batteries in all sensors plus the battery in the service panel in January 2015.

No RF changes that we are aware of...the check sensor happen for 2 windows in two separate rooms so far.

It could be anything. We live in an electronic noise environment far more cluttered than existed when these transmitters/receivers were first designed. It could be something as small as a neighbor that's taken up ham radio...

There is a setting (*22 RF Jam (detect) option) that I recommend turning OFF. Frequently ADT turns it on by default, but in the real world, deliberate wireless jamming is really not that easy to do, and is well beyond the skill level of the type of opportunist thieves you are trying to protect against.

If you have an alphanumeric keypad, you could check the panel's event log to see the specific trouble code being generated.

I imagine Ron is on the right tracking thinking it's an RF Supervision issue but it could be tampers going bad on the sensors as well.
