2: City Box Connection Using The 5220 Module - Honeywell Farenhyt Series Installation And Operation Manual

4.17.2 City Box Connection Using the 5220 Module
This section describes how to connect the control panel to a municipal fire alarm box or "city box" as required by NFPA 72 Auxiliary
Protected Fire Alarm systems for fire alarm service. The city (master) box is an enclosure that contains a manually operated transmitter
used to send an alarm to the municipal communication center which houses the central operating part of the fire alarm system.
City Box Standby Current:
Alarm Current:
The maximum coil and wire resistance (combined) must not exceed 30 ohms.
To install the 5220 for city box connection:
1. Use one of the knockouts on the right side of the control panel to connect the 5220 using a short piece of conduit (must not exceed
20 feet in length).
2. Wire the 5220 to the control panel as shown in Figure 4.47. This drawing also shows how to connect the city box coil to terminals 3
and 4 on the 5220. Do not install an EOL resistor in the terminals of the NAC circuit used for this application.
3. Connect earth ground wire to the 5220 chassis with mounting screw.
