4.18.2 City Box Connection Using the 5220 Module
This section describes how to connect the control panel to a local energy 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 sys-
tem.
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 (must not exceed
20 feet in length).
2.
Wire the 5220 to the control panel as shown in Figures 4.55. This drawing also shows how to connect the city box coil to terminals
3 and 4 on the 5220.
3.
Connect earth ground wire to the 5220 chassis with mounting screw.
4.
Program the NAC circuit used as a notification circuit, continuous and non-silencing. Refer to Section 9.5 for point programming,
Section 9.4 for group settings, and Section 9.3 for zone settings and mapping.
