Optional Radio Connections
4. Insert the plug back into its terminal and confirm the wires are in the correct slots.
Sense Input Connections
All of the sense input connections to the Station Transponder Unit are made to connectors
P7 and P8 on the I/O and Power Supply board, which is mounted on the rear panel of the
case. For this reason, it is most convenient to bring relay control wiring into the case
through the grommet located behind the IP Network and Handset jacks.
Refer to Sense Inputs (P7 - P8) on page 156 for details about the connector pinouts for the
four sense inputs.

Making Sense Input Connections
1. Route the sense input wiring up through the grommet in the bottom of the unit.
2. Remove the plug from the appropriate connector on the I/O and Power Supply
board.
3. Insert the wires into the correct terminal slots and tighten the screws to secure
them.
4. Insert the plug back into its terminal and confirm the wires are in the correct slots.
Optional Radio Connections
While the Fire Station Alerting System is designed to send both dispatch/control
information and voice audio back and forth over the IP network, the system can be
installed with the voice audio being sent back and forth over radios. If the system you are
building is using radios, the example that follows shows the typical connections made
between the radios and a pair of Station Transponder Units.
If your fire stations have only one Station Transponder Unit installed, you may simply
ignore the connections shown to a Model 6204.
Conventional Radio Setup
This section describes the set up used with a conventional base radio. The use of trunked
radios for this application is not recommended. See
Figure 42 .
Model 6203/6204 Programming
• In the serial programming menus for the Station Transponder Unit, set Comm
