Secondary Reporting
The Secondary Reporting configuration of the Metasys Intelligent Fire
Network (MIFN) provides secondary (ancillary) reporting of alarm and
trouble conditions on a standard Operator Workstation (OWS). Unlike the
Primary Reporting configuration of the MIFN where the Fire OWS is
UL 864 UOJZ listed as a Proprietary Protective Signaling Station, the
standard OWS in the Secondary configuration is not UL Listed for fire
alarm operation and only serves as a Secondary annunciator for the MIFN.
For example, in the Primary Reporting configuration, the Fire OWS can
reset the fire controllers. However, in the Secondary Reporting
configuration, the control of the fire alarm panels is limited to viewing and
adjusting detector sensitivity, enabling or disabling alarm verification, and
enabling or disabling day/night sensitivity. The standard OWS cannot
acknowledge alarms, control fire points, or reset IFC panels, as can the
Fire OWS.
In the Secondary Reporting configuration, the MIFN can only be
configured to operate as a Local Protective Signaling System, which
essentially operates as a standalone Fire Network as shown in Figure 3 of
the Intelligent Network Annunciator (INA) Technical Bulletin
(LIT-448193), independent of the Metasys system, and the Metasys system
is simply a Secondary Reporting system.
The Secondary Reporting configuration is installed the same way as the
Primary Reporting configuration; however, there are a few exceptions:
• Secondary Reporting utilizes the standard NCM350.
• Secondary Reporting is rated for Style 4 configuration with the
NCM350 on the end of the communication chain.
• Secondary Reporting is not UL Listed as a smoke control system.
• Secondary Reporting can be tied to an N1 Ethernet network.
• A UPS is not required for the OWS or NCM.
• The UL 864 Workstation and Watchdog Timer are not required.
• The Secondary Reporting configuration of the MIFN can only operate
as a Local Protective Signaling System.
There can be a maximum of four nodes (IFC-1010/2020 panels) connected
to the Fire NC on the Secondary Reporting configuration of the MIFN and
any combination of Fire and/or INA devices.
