4.2 COMPONENTS NECESSARY FOR INSTALLATION
The following components and accessories are used when installing and operating the FMN /
GWN as part of a system (see section 6.0 for installation instructions):
Power cable (IWT P/N: FAA4200-007):
The power cable for the DC supply input CON1 is an MSHA approved flame resistant, 2-
conductor, 18 AWG with a 4-pin Universal Mate-n-Lok connector.
Power Supply:
The specific power supply used to power the FMNs and GWNs will depend on the requirements
of the system in which they are installed. The DC power supply must be capable of supplying
16VDC – 24VDC and 3 Amps to the FMN / GWN.
Backup battery assembly (IWT P/N: FAP9100-001):
The backup battery is a 6V sealed lead acid battery housed in a rugged plastic enclosure. The
battery assembly connects to the FMN CON2 via an MSHA approved flame resistant cable with
a Universal Mate-n-Lok connector. The battery supplies a 6V intrinsically safe input to the FMN.
Only the FAP9100-001 battery assembly has been approved by MSHA for use with the FMN
when installed in coal mines.
Antenna (900 MHz):
The specific 900 MHz antenna connected to the FMN / GWN RF port depends on the location of
the FMN / GWN.
Above Ground (FCC Certified): Laird Technologies OD9-5 or equivalent
Below Ground (MSHA Approved): M-2 Antenna Systems, Inc. 902-5 or 902-5MA
The particular antenna models listed are the ONLY antennas that may be used with the FMN /
GWN in applications where either FCC or MSHA requirements must be met.
RF Power Splitter:
A 2-way, 3-way, or 4-way power splitter may be used depending on the specific FMN installation
configuration used – i.e. the FMN may be installed with up to four 900 MHz antennas.
RF Coax cable (IWT P/N: RCL4100-001):
The coax cable connecting the antenna port of the FMN to the 900 MHz antenna is a MSHA
approved, flame resistant cable with N-connectors.
