The BG alarm project consist of E47ADCN , 3486 , 4 sets of F482 ,connecting key and 12 v Bticino ' s battery as back up battery. The problem are followings:
1. if main power of the system was cut off the new external siren 4073 and IS 4070 rang loudly for a few sec and then 3486 controller also turn off . At the log event said "SCS BUS OFF". Why battery does not supply the system?
I have try to change 3 PCs of battery but the same and also battery was excited by Car battery charger shop.
2. At the testing period, the Internal siren alarm only few sec just about 4-5 sec then stop. The system was tested by leave the system in ON (not arm) mode and maintenance mode for more than a week but the same.
3. The External siren 4073 was some time non stop flashing after given an alarm but not able to turn off only reset the bus can turn it off. We also try to turn the menu External siren flash in off but some time happens. I do not know why?
Thank you and best regards,
