2 Introduction
This publication describes the installation procedure for the City Circuit Card with Disconnect Switch 2050-9909.
2.1 Inspecting the contents of shipment
Upon unpacking your Simplex product, inspect the contents of the carton for shipping damage. If damage is apparent, immediately file a
claim with the carrier and notify your local Simplex product supplier.

3 Overview
The 2050-9909 city circuit card is used to annunciate alarms and other urgent indications to remote facilities. When the 2050 or 2250
control unit goes into alarm, the city card circuits are activated and annunciation immediately occurs at the remote facility. Reverse polarity
modules or local energy modules, used for reaching the Public Service Fire Communications Center, receive annunciations at the remote
site. The city circuit module has two circuits, that are configurable for alarm, trouble, or supervisory reporting. In the event of a CPU failure,
a city card configured for a trouble output sends a trouble to the city circuit.
Note: You can only install one city circuit card for each system.

4 Mounting the city circuit card inside the cabinet
Complete the following steps:
1. Remove the AC power at the breaker from the control unit.
2. Open the cabinet and disconnect the battery.
3. Locate the city circuit card in the enclosure by using the locating features provided.
4. Mount the card on the top right corner of the cabinet by using the two provided, number six Torx screws.

5 Communications and power connection
The city circuit card comes with a power and communication harness. You can use this harness for interfacing the city circuit card with
the 2050 or 2250 control unit. To connect the harness, complete the following steps.
1. Connect one end of the power and communication harness to P1 on the city circuit card.
2. Connect the other end of the power and communication harness to the connector labeled P18 on the 2050 or 2250 control unit.
3. Apply battery power.
4. Apply AC power at the breaker.

6 City card configuration
6.1 Configuring the city circuit card
Use the information in Table 2 and Setting P6 to set the jumper positions for reverse polarity and local energy operations.
Table 2: Jumper positions
Reverse polarity Local energy
City circuit 1 P3: 1-2, 3-4, 5-6
P2: 2-3
P3: 7-8, 9-10
P2: 1-2
City circuit 2 P5: 1-2, 3-4, 5-6
P4: 2-3
P5: 7-8, 9-10
P4:1-2
6.2 Setting P6
You must select either supervisory or trouble operation for circuit 2 by setting P6.
• To configure city circuit 2 for supervisory activation, install jumpers on port P6 to positions 1 and 2 and another to positions 3 and 4.
City circuit 1 sends a trouble to the city by dropping circuit power when reverse polarity is selected.
• To configure city circuit 2 for trouble activation, install a jumper on port P6 in positions 2 and 3. City circuit 1 sends alarms only to the
city.
6.3 Configuring disconnect settings of the city circuit card
The 2050-9909 city circuit card has two disconnect switches: SW1 for city circuit 1 and SW2 for city circuit 2.
Turn the switches to the ON position for normal operation and to the OFF position to test the system without transmitting alarms to the
city.
6.4 Software requirements
Add the city circuit card to the system configuration. For more information on adding the modules to the system configuration refer to the
2050 and 2250 Foundation Series Fire Alarm Control Units Operation Guide 579-1405 and the 2050 and 2250 Foundation Series Fire Alarm
Control Units PC Programmer Installation Guide and Programming Instructions 579-1421 .

7 Field wiring city card circuits
7.1 City circuit card guidelines
For successful wiring, adhere to the following guidelines:
• Ensure all wiring is supervised, but not power-limited.
• Ensure conductors test free of all grounds before you connect the city card to the system.
• If the wiring is routed externally, it requires overvoltage protection at the entrance or the exit of the building. Install the 2081-9044
module inside a UL listed electrical box at the entrance or exit where the wiring is routed. A maximum of four 2081-9044 modules can
be connected to one channel.
• Ensure wiring for reverse polarity is between 20 AWG minimum and 12 AWG maximum.
• Ensure wiring for local energy is between 18 AWG minimum and 12 AWG maximum.
7.2 City card circuits wiring
To wire the city circuit card for reverse polarity or to a local energy master box, see Figure 4 and the notes on city circuit card wiring.
All wiring is terminated at TB1 on the city card. Leave the 2.2 K Ohm, 1/2 W resistor, part number 378-038, installed from the + to the -
terminals of unused circuits on TB1.
Figure 4: City circuit card wiring
Note:
1. The city circuit card is intended for connection to a polarity reversal circuit of a remote station receiving unit that has compatible
ratings: 19 VDC to 32 VDC, 2 V peak to peak ripple maximum.
2. The city card is intended for connection to a 14.5 ohm trip coil.
