My alarm was set off this morning about 10 minutes after I left home. I quickly made it back home to see everything was fine. The alarm was not even making a sound, but the panel showed the alarm was going off. After turning the alarm off, I looked into my alarm.com account and 1 sensor keeps showing tamper and end of tamper alerts every few minutes since the alarm went off this morning. I checked the sensor and the cover seems to be on tight and in place. Any ideas what could be causing this and what I can do to fix it. I am unable to arm my alarm until it is fixed.
The siren will timeout after a period of time set in programming, and will only kick back on if another sensor is tripped after. It looks like the door sensor in question reported opening (causing the alarm) and never closed. So when you went back in, presumably through that door, you would not have set off the siren again. So that is normal in this circumstance.
Now, if the door was actually shut tightly and the sensor or magnet was not moved or damaged, then it’s certainly not normal in that respect.
What model of sensor is the one you are referring to?
It is a 2gig dw10. The door was shut tightly and locked and has been ever since, but every few minutes it shows a tamper alert then an end tamper alert a few minutes after. It’s been going on for about 7 hours…
On the DW10-345 there is a little plastic tab which snaps the case shut. Is that tab loose or damaged in any way? Tampers being thrown out like that are almost always indicative of a physical issue of some sort.
I’m not seeing any tampers in the last few hours, but I do see a fair number of them reported from that zone, ranging in duration from 2 seconds to 8 minutes or so.
Has this sensor had its batteries replaced? Can you cause a tamper by pressing on the case and letting go, or pushing a bit on the side? This would just be checking the switch’s sensitivity.
When you open the sensor, the tamper switch is a tiny black switch near the latch.
The batteries were replaced about 3-4 months ago and has been fine until today. The sensor looks fine, but just pressing on it sets off the tamper alert.

That’s actually a good thing. Might be a simple physical issue then instead of a malfunctioning sensor radio. Best thing to do is pop off the cover and take a look for any cracks. Make sure there are two small tabs, sort of act like hinges, at the bottom end opposite the latch. If you do not see any damage try depressing the little black tamper switch. Does it reliably cause tamper to go away and return on the panel?
If all looks right, reattach the case carefully, make sure it is flush. Then press on it. Once the case is on you should not be able to cause a tamper by touching the sensor. If so, the sensor will likely just need to be replaced.
Is the sensor portion on the door itself? Curious if a door slam may have jostled it.
I took the cover off and everything looked fine and pressing and letting go of the tamper button worked every time. when I put it back together the issue was still there. I took the cover back off and noticed that the mount seemed slightly loose so I tightened it down really good. I put the cover back on and now I can push on the sensor all I want the the alert will not come up! Looks like that may have been the issue!

Hey great news! Yep, it is almost always a physical issue of some sort, sometimes non-obvious, if you have a sensor throwing out tampers. Glad to hear it is resolved.
