NFPA -72 - DACT connection

Question asked by msanders on Feb 9, 2017

DACT is required to be connected upstream to the public switched network.  On a campus with several alarm panels, is it permissible to have the FACP run through the campus phone system (Dial "9" to connect) prior to the Public network pathway.


2010 code revised definitions to allow for  Managed Facility networks (MFVN) to be used as part of the public network.  How can you determine if the campus phone system meets the requirements of the MFVN.


Priority line capture and dialing protocol are maintained.
