Still very pleased with our alarm system but had interesting time today.
After nearly three years one of the batteries in a PIR sensor decided it was low and sent the appropriate message to the control panel. So the panel stars going BEEP and continues to BEEP every min or so. Not having a battery to hand I wanted to suppress the BEEPING...
The manual isn't clear on this point and it's hard to concentrate when you know it will BEEP any moment. Eventually discovered you can "Bypass" a sensor to tell the control panel to ignore it. That appeared to work so I sat down to watch TV.
Short while later the BEEPing start again. Persistent bugger, I thought and get the manual out again. This time I discover you can turn off the "Trouble beeps". A few key presses and I'm convinced I've killed the beast this time.
Certain it was dead I went to my office and sat at my computer. Suddenly my mobile phone rings and it's the alarm system ringing to tell me about the low battery again. I'm now convinced it's haunting me
