Wiring Guidelines
This section contains guidelines for wiring the zone modules.
General Guidelines
Make sure these guidelines are accounted for before wiring:
• All wires must be 18 AWG, twisted/shielded pair.
• All wiring is supervised.
• Conductors must test free of all grounds.
• Power must come from a 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.
• In areas of high lightning activity, or in areas that have large power surges, the 2081-9027 Transient Suppressor should be used on monitor
points.
• 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.
