I have an Aritech CD 72

When I power up the system for the first time and enter the default Engineer Code 1278, I get a message saying 'Cannot Disarm' followed by 'System Armed'

Not really sure what to make of it, can anyone help?

Many Thanks,

Dan

Evening, you need to disarm the system first, try 1122, should be the default customer code. May have to disarm it a couple of times depending on if youve got mains connected or anything in tamper etc.

Depending on software version it may start to coundown and show "open lid" when engineer code is entered, make sure that both your aux tampers are linked out before you start. One should be a hard wire link and the other should be a 4k7.

Hope this is of some help.
