Hello At present I have a hired alarm system (in Sweden) from Honeywell, the main central is a CMI8NE-SDI4G (with mobile as well as wired telephone connection) I will not renew the rental agreement when it ends soon, hence the CMI8NE-SDI4G will be returned to the company. All other Items such as one keypad (CSK8NE-SDI-, two smoke detectors (DTO600HF-, one PIR (IRX800HFCT- and one magnetic switch (DOD800HF- will stay as my property. I will like to buy a new main central and have found a CMI8UK-STD, will this be compatible with the items mentioned above, and can it all be programmed by using a TCU2-800 mobile keypad? Flemming
