Remote Station Applications Control Panel Installation
4.19.2 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 Pro-
tected 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: 0 (Notification supervision current accounted for in control panel draw.)
Alarm Current: 1 Amp for 1 second 27.2 VDC max.
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. Conduit must not
exceed 20 feet (6.1m) 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.
4. Program the NAC circuit used as a continuous and non-silencing. Refer to Section 8.5 for Point Programming, Section 8.4 for group
settings, and Section 8.3 for zone settings and mapping. It is not possible to reset the remote indication until you clear the condition and
reset the control panel.

This is not suitable for remote station protected premises
service where separate transmission circuits are required for
fire supervisory, if applicable, and trouble signals.
This is intended for connection to a polarity reversal circuit of a
remote station receiving unit having compatible ratings.
All circuits power-limited.
All wiring supervised.
