Glassbreak false alarm (caused by low battery?)

I — and likely several of my neighbors — was just awoken by one of my glassbreak sensors (located in the daylight basement) activating a full alarm. I surveyed the house, saw nothing, disarmed the alarm — and continued to find nothing. No window, bulb, glass, anything.

Then I took a closer look at my SS app's "Notification" pane. At the exact same minute — 11:41pm — that this sensor tripped its false alarm, its immediately-preceding event was broadcasting that it had a low battery.

I've read enough of these posts to see that the answer to "hey, could a low battery trip a false alarm?" is, constantly, "no, that's impossible." But in this case, I can't fathom what else could have happened. And, if that's how these sensors work, then am I due for another false alarm the next time one of these runs low?

Hi @Rowsdower,

 

This is definitely a bit of a mystery. But yes, low batteries in general shouldn't be able to cause false alarms. It should be the opposite - when the battery gets very close to dying, the sensor's range might deteriorate, resulting in the sensor not triggering at all. That's why it's important to change the battery as soon as you see that warning.

 

How long has it been since you last changed the battery? If you're past the 3-year mark, then it might actually be time to change. And coincidentally, there might have been an environmental trigger (for Glassbreak, other that actual broken windows, that could be the barking of some dogs, lightning, sound effects from a TV, etc.).

When the Glassbreak was activated, it would have also sent an update of its current battery state, which is how it showed up on the app.

 

One more thing: When was the last time you updated your Base Station's firmware? If the system is behaving strangely, it would be a good idea to update to make sure that it's not an issue with the programming. You can find instructions for updating here.
