22.7 EPS and IDNet 2 Wiring
This chapter describes the EPS wiring. This includes the wiring of the IDNet 2 card.
22.7.1 EPS Wiring Overview
22.7.1.1 General Wiring Guidelines
• Conductors must test free of all grounds.
• 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 earthground.
• 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.
• 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 per NFPA780.
• Only system wiring can be run together in the same conduit.
22.7.1.2 Power-Limited Guidelines
• Non-power limited field wiring (AC power, batteries, City connection) must be installed and routed in the shaded areas shown in Figure
116.
• Power-limited field wiring must be installed and routed in the non-shaded shown in Figure 116, with the exception of City wiring.
Excess slack should be kept to a minimum inside the back box enclosure. The wiring should be neatly dressed and bundled together
using wire ties. Anchor power-limited wiring to tie points.
• Tie the wiring located between bays to the internal wiring troughs, if applicable.
• When powering remote units or switching power through relay contacts, power for these circuits must be provided by a power-limited
power supply listed for fire-protective signaling use.

Table 37: EPS Trouble Messages
Definition
Appears when a short is detected on the IDNAC channel. This status clears automatically when the short
circuit is removed.
Appears when each device on the IDNet channel has been configured, and when none of the devices are
communicating on the channel. This message does not appear if there are no configured devices on the
IDNAC channel.
