This could be a lot of things and it is dependant on what keypad you have. It could be a cell tower signal loss or interference, it could be a router or modem issue on you devices, it could be one of 11 other things. IF you have the vista keypad, look for a four digit error code extension.

New apartment with A honeywell ademco 4110xm. I connected power and got master code. I get CHECK 05 and ALARM 06. Typing the code and OFF disables the ALARM 06 error, but Check 05 remains. Any help?

It is telling you that a zone is not working properly or is open. Ex. door not shut, window not shut. Something moving in front of a motion sensor. Fin out what zone 5 is and that is your problem for arming. Could be a battery if this is a wireless system.

My alarm system insist that the exit door is open. I checked the roller contact and if i depress it and let it go the chime rings - so how can i test the switch - there is two doors one going out side...

Pull the plug from the switch and jumper the wires. If the error goes away, the switch is toasty and need replacing. If the error doesn't go away, you've got a broken wire, or a faulty base unit.
