NESS Alarm D8XD 110-869 Main Board PCB1 x Ness D8XD PCB only NO resistors The traditional PSTN Landline telephone network has been decommissioned across Australia as part of the nationwide NBN rollout. As a result, this product is no longer capable of reporting alarms via telephone. However, it can still be used as a local alarm system. For back to base monitoring we recommend the Ness XCEL 4G or DPlus range of alarm panels using Armor IP reporting format.
