Wiring
Describes guidelines and instructions for wiring the module to RS-232 devices.
General Guidelines
Make sure these guidelines are followed before wiring:
• All wires must be 18 AWG (0.8231 mm²), twisted-shielded pair.
• All wiring is supervised.
• Conductors must test free of all grounds.
• Power must come from an Simplex approved power supply.
• All wiring must be done using copper conductors only, unless noted otherwise.
• If shielded wire is used:
- The metallic continuity of the shield must be maintained throughout the entire cable length.
- The entire length of the cable must have a resistance greater than 1 Megohm to earth ground.
• Underground wiring must be free of all water.
• Wires must not be run through elevator shafts.
• Wires that run in plenum must be in conduit.
• Splicing is permitted. All spliced connections must either be soldered (resin-core solder), crimped in metal sleeves, or encapsulated with an
epoxy resin. When soldering or crimped metal sleeves are used, the junction must be insulated with a high-grade electrical tape that is as
sound as the original insulating jacket. Shield continuity must be maintained throughout.
• A system ground must be provided for earth detection and lightning protection devices. This connection must comply with approved earth
detection as indicated in the NFPA780 standard.
• Only system wiring can be run together in the same conduit.
• Any wiring leaving the building requires overload protectors (2081-9044). Use one overvoltage protector where wiring leaves the building and
another where the wiring enters the other building.
RS-232 Wiring
Wire RS-232 devices to the terminal blocks on the RS-232 card. The cables and connectors are not supplied.
Refer to Figure 7 for the pin-outs of these terminal blocks and connectors.

Note:
1. RS-232 Power - 10 mA (maximum) per signal.
2. All wiring is supervised.
3. All wiring is 18 AWG (0.8321mm) or in accordance with the local code.
4. Use of CTS line is required (with or without supervised circuit).
