Silence Phone Line Error Condition

[lagman <dan_hoffard@xxxxxxxxxxxx>]

All,

I have a DSC PC 1555MX.  We have recently turned off our land-line
phone service and started using VoIP.  Since there is no phone
service, the alarm beeps every 30 seconds or so.  Is there any way to
silence this?  We don't have monitoring, so it really does not even
need to be plugged into the phone line.

Thanks,
Dan
