Battery Test will occur at the same time each day, for 2 minutes
In that time, the battery will power the system, so there is a voltage drop from 13.8V to 12V (or below if the battery is not good). The voltage drop should not affect a good PIR. A battery can supply enough to power all the modules, PIR, TWS etc
Check the event log if the false alarm occurs at the same time each day
