I have had this alarm for a few years and had eng in the past come and replace battery on PIR. I tried doing it my self but keeps warning me of tamper and I cannot clear it with my user code. I dont have engineets code , is there anything I can do as I've tried all the default codes 1111 2222 1234 etc.
I really don't know what to do as I cannot afford an engineer as I've been furlowed due to corona ?
