My alarm went off and now shows that something is wrong in zone 3, the main level of my home. I opened all the windows and reclosed them, but can not get the alarm to come back on. Ay suggestions?


If it's a wireless alarm, it could be that the batteries are flat in one of the sensors. However, your panel should tell you this. Any recent renovations could also have upset the wiring.

If tampering occurred (possibly due to a nosy transient), you might have to reset the alarm.
