To connect Fire Alarms to the Fire Brigade and ALARMSWITCH using broadband, a Fire Alarm interface server is required to be installed. This server converts protocols like SGD and manufacturer’s proprietary formats to open standard CSV or XML. Once connected via a Fire Alarm server the Private Fire Alarm (PFA) or the Sprinkler Direct Brigade Alarm (DBA) can pass extended Alarm data such as zone and point information directly to the Fire Brigade.  The Broadband modem/router that Fire Alarm servers are associated with, are also powered from an alarm power server unit (APSU) to ensure network connectivity and reliability is beyond 99.7%. All of this equipment together is mounted into a secure service demarcation point (SDP) and becomes the Fire Alarm Network Access Device (NAD)
