Posted By: DT98 Voltage for alarm line cut monitor - 10/11/11 12:00 PM
The line cut monitor used on our alarm systems will think any off hook line voltage below 10 volts is a cut phone line.
All the phone lines used on the alarms are shared with phone system use via an RJ31X jack...pretty standard stuff.

Is there a line cut monitor unit out there available that is adjustable so it will trip at a lower off hook line voltage other than 10 volts?

Thanks, DT98
