INSTALLATION INSTRUCTIONS
Installation Overview:
Recommended electrical requirements for monitor:
 Power and Ground wire gauge and length: Distance Ft. (m) Wire Gauge (AWG)
100 (30.5) – 150 (45.7) 8
< 100 (30.5) 12
 Power and Ground wire type: Cross Link or equivalent (Must meet or exceed NFPA 1901 Section 13)
 Maximum monitor amperage draw: 20 AMPS (35 AMPS for Foam Tube Expansion)
 CAN wire gauge and length:
o
Main Line: 131 ft. (40 m) – 18-20 AWG (Must meet J1939 specification)
o Branch (node) Line: 3ft. (1 m) – 18-20 AWG (Must meet J1939 specification)
 CAN wire type and shielding: Twisted shielded pair - 105°C 150V (Belden 9841 series or equivalent)
o
Shield Drain: Connect shield/drain to pin C of J1939 connector
Recommended electrical requirements for the 7000 series input devices:
 Power and Ground wire gauge and length: 18-20 AWG 105°C 150V up to 150 ft. (45.7 m)
 Maximum input controller amperage draw: 500mA
 CAN wire gauge and length: 3 ft. (1 m) – 18-20 AWG
 CAN wire type and shielding: Twisted shielded pair - 105°C 150V (Belden 9841 series or equivalent)
o
Shield Drain: Connect shield/drain to pin C of J1939 connector
 Docking station wire gauge type: 20 AWG cross link or equivalent
Termination Points:
When using CAN lines for communication there must be 2 termination points within the system.
Termination points are explained further in the Configuration section (installation step 2). What is
important at this time is that in order to maximize the efficiency of communication in your CAN
network, you must terminate the two components at the extreme ends of your main CAN line. This
should be taken into consideration as you setup your EXM system. Each additional EXM component that
requires connection to the main CAN communication line between the two end components will
require the use of CAN Connector Kit (P/N 37221000). The maximum length of wire from the main
CAN line is 3ft. and would be considered a branch (node) off the main CAN line.
CAN Connector Kit:
You may install any of the EXM CAN components that require
the use of a CAN Connector Kit (P/N 37221000) by plugging
the tri-pin CAN connector from the EXM component directly into
the wye connector (Deutsch DT04-3P-P007) of the CAN
Connector Kit. You can also use the crimp connectors on the
mating connector leads to make your own connection.
Step 1 – Mount and Wire All System Components
Step 2 – Configure the EXM System (If Required)
Step 3 – Calibrate the EXM System
Step 4 – Check Installation
