Ended a 6 month battle with false alarms using a $5 part
Had a customer in Southfield whose system kept going off around 3 AM for no reason. Replaced the panel, rewired the motion sensors, everything. Turned out the battery backup was slightly loose in its cradle. Put a small zip tie on the terminal clip, zero false alarms for 3 weeks now. Anyone else have something dumb like that eat up your time?
