4. Make sure the MIB-OWS interrupt selector jumper is set to IRQ3
and plug the MIB-OWS board into the available ISA slot, fitting
the ends into the ISA and empty slot.
5. Replace the two screws on the top of the ISA slot and empty slot
and screw down.
6. Place the ISA slot cover back on and fasten with two screws.
Mount the Fire-Net NCM in either a Fire Watchdog Enclosure or a
standard UPM enclosure. For information on mounting and wiring the
Fire-Net NCM to the Fire Watchdog Enclosure, see Fire Watchdog
Enclosure in the Application Details section of the Fire Operator
Workstation (Fire OWS) Technical Bulletin (LIT-636014). If you are
using a standard UPM, see the Design Considerations section of this
document.
The MIFN works in conjunction with the Metasys N1 LAN to provide
complete fire alarm, security alarm, and HVAC control. The Fire
OWSs and Fire-Net NCMs are connected to both the MIFN and N1
LAN. The MIFN is the fire system communication path; however, if
path resources are available on the N1 LAN, fire system
communication may use the N1 LAN.
When the fire system requires commissioning and/or maintenance,
communication uses the N1 LAN. In addition, the N1 LAN provides
the interface between the fire alarm, energy management, and smoke
control systems.
Media Options: N1 LAN
For details on the N1 LAN media options, see the N1 ARCNET Local
Area Network Technical Bulletin (LIT-636017).
Note: Use fiber-optic cable when connecting network nodes
between buildings or, if you are using twisted pair, wire it in an
underground conduit separate from all power wiring.
Media Options: MIFN
Use twisted pair copper wire, fiber-optic cable, or a combination of the
two to provide communication between the nodes of the MIFN. There
are MIB-OWS models available with each of these cable options.
Note: To comply with UL Requirements, use fiber-optic cable
when connecting fire network nodes between buildings or if you are
using twisted pair, wire it in an underground conduit separate from all
power wiring.
