Dear Mr Stevens,
Thank you for taking my call earlier today.
I am sorry to hear that you keep receiving a message through the alarm to notify you that it has been disconnected.
On further investigation, as the alarm is being used with the Virgin Media box the set up is slightly different and I have sent you an email with full in-depth instructions on how to set this up.
I hope this resolves the issues, however, should you require any further assistance, please do not hesitate to contract me.
Kind Regards
Anny
