I have a Paradox Spectra 1759MG home alarm. It is configured to call my cellphone first, and a landline number second when it is activated. The landline was my work DDI at my desk - but unfortunately I no longer work there after 10 years. Reading the manual, changing it seems relatively simple:
enter INSTALLER CODE (default 0000/00000)
enter section you wish to program (152 in my case)
enter phone number
However, it doesn't seem to work, and I get a long beep after entering 0000 at the installer code section , and similar beeps when I continue the sequence, beeping mid entry of the phone number. So I have used clear to cancel the process(although likely i'm not even in program mode yet?)
Is it likely the installer has changed the installer code and that's what is stopping me?
When the correct number is entered, what does a confirmation tone sound like?
Thanks for any help !
