hello, I recently bought a house with the above alarm fitted. It recently stopped working (ADT alarm). It just has stars on the panel *********** (like that) and occasionally says managers re-set required. I contacted ADT who said it's not one of their fitted and monitored alarms and someone got an ADT alarm and fitted it. I will have to pay £150 to have it reactivated and then a monthly contract. That's not the issue though, more the problem is that it's going off during the night & I don't know how to switch it off & ADT won't do it as it's not their alarm! Help
