I received this message when I disconnected the telephone line from my Napco p816 panel because a central station person called me and mentioned that our alarm went off (which it did) and they do not have us listed as a client (which we are not)
How can I disconnect the modem and not get this message on the keypad? I have a laptop and the quickloader software but I am not sure if the dealer code will work if this was programed by someone else.
Thanks for your help.
