Hi guys, i have a fault on the panel saying its jammed, reading the manual this means that there is a raido frequenzy signal blocking the PIRs signal to the panel. I have nothing new or on within the house so am stuffed at knowing what it is..Can anyone help how i find out and or how to remedy the beeping is driving me mad (Even though i can silence it every 4 hours)...Thnaks in advance..Its a powermax Plus.
