Low battery causes alarm, system resets itself?

Hi @greg_111,

To keep it simple, no, a low battery cannot cause a Motion Sensor to trigger an alarm. Generally though, the batteries in your sensors should last about three years before needing to be replaced. Motion Sensors are slightly more prone to false alarms than our other sensors simply because of the way that they work.

Technically speaking, SimpliSafe Motion Sensors don't actually detect motion; they are PIR motion sensors which means that they actually detect heat. It's the sudden change in the amount of heat that the sensor "sees" that will trigger the alarm e.g. when someone walks in front of a motion sensor, there will suddenly be a lot more heat that it "sees" setting off the alarm.

With regards to your other question about the system being armed when you arrived on the premises, that is because once the siren on your SimpliSafe system has stopped blaring, the system will automatically re-arm itself to make sure that the property is still protected.

I understand about the reset and think it's a good feature. However, my system, since the time of purchase, has twice (in the wee morning hours, no less) given a false positive panic alarm that we can only attribute to dying or dead batteries. The first time we were sleeping and the second time we were out of state. No panic alarm was intentionally triggered by a human, therefore, and we do not have any pets. No one broke in.

Both times it was a keypad. Replaced the batteries, and there weren't any more issues. Hard to believe it was any other reason.

Hi @ssarfati,

As it's not possible for low batteries to cause an alarm to trigger, it seems more likely that there may be an issue with the Panic Button on the Keypad itself. We'll make sure to have one of our Specialists follow up with you to make sure you don't have this issue again going forward.
