Thanks you for your constructive reply. The system was fitted when I purchase the house and I don't have a manual. I not touched or amended the system in anyway. The system has functioned well except for the last few days, the unit bleeps and time this sensor is activated.
I have a motion sensor that continually sound an alarm bleep anytime some passes it when the alarm is not set. I've tried resetting the system and checked the motion sensor but it continues to bleep. Can anyone help please? :cry:
