City Connect Module Wiring
• City connect module mounts to the main system as
shown. Refer to City Module Installation Instructions
for details.
• City module consists of two circuits that are jumper-
configured. Circuits may be configured for reverse-
polarity or local energy operation. See jumper setting
table for details. Modules must also be added to the sys-
tem configuration. See “System Options” later in this
manual.
• All wiring to be per NFPA-72, NEC, and local codes.
Minimum 20 AWG for reverse polarity circuits; mini-
mum 18 AWG for local energy circuits.
• Wiring is supervised for opens and grounds, but not
power-limited.
• Conductors must test free of all grounds.
• For specific information about reverse polarity and local
energy circuits see Figure 2-14.
• If wiring is routed outside the building, use of a listed
secondary protector is required. Use Simplex Model
Number 2081-9044. A protector must be installed at
each location the wiring enters or exits a building. Each
2081-9044 adds 6 ohms wiring resistance and is rated
for 200 mA. Maximum wiring resistance is reduced by
6 ohms for each 2081-9044 used.
• Circuits are shipped with 3.3K, 1/2W resistor installed.
Remove resistor before wiring circuit. Leave installed
on unused circuits.
