sequential PIR activation: maybe power failure?

This is strange, and I suspect a battery failure: a Comfort II Ultra system (v5.233) in a remote site went amok just an hour ago because ALL PIRs (zones 25-30) connected to a slave panel gave false positive signal at exactly the same time:

06/24 20:43 Alarm Type # ZoneAlert (6)
06/24 20:43 Zone Activation # PIR_diadromou_or (25)
06/24 20:43 Alarm Type # ZoneAlert (6)
06/24 20:43 Zone Activation # PIR_BA_ypnod (26)
06/24 20:43 Alarm Type # Intruder (1)
06/24 20:43 Dial Number # 1
06/24 20:43 Alarm Type # ZoneAlert (6)
06/24 20:43 Zone Activation # PIR_diadromou_or (25)
06/24 20:43 Alarm Type # ZoneAlert (6)
06/24 20:43 Zone Activation # PIR_BA_ypnod (26)
06/24 20:43 Alarm Type # Intruder (1)
06/24 20:43 Alarm Type # ZoneAlert (6)
06/24 20:43 Zone Activation # PIR_BD_ypnod (27)
06/24 20:43 Alarm Type # ZoneAlert (6)
06/24 20:43 Zone Activation # PIR_NA_ypnod (28)
06/24 20:43 Alarm Type # Intruder (1)
06/24 20:43 Alarm Type # ZoneAlert (6)
06/24 20:43 Zone Activation # PIR_ND_ypnod (29)

The system has been sending me battery warnings for some time but I haven\'t serviced it yet. Am I true to suspect that when the system runs the daily battery test, all PIRs connected to the panel with the faulty battery reset due to voltage drop, and this causes the alarm?

thanks in advance!

When the system runs battery test, the AC is switched off and it runs on battery
Hence if the battery is very low it could cause them to be activated
It is best to take action when the battery test is reported because battery backup is very important
