Connecting the Control Head
In addition to the connection through the 25-foot Convergence Network cable, the
control head has:
• Connections for four active-low input circuits that activate when pulled to
ground (17500308)
• Connections to the siren for battery ground (–GND) and +12 Vdc switched by
ignition or b12 Vdc for ignition timers (17500308)
• Connection for optional ignition sense (+12 Vdc) for ignition timers (17500308)
• Connection for the Federal Signal public address microphone (258B577-03)
• 25-foot cable that connects the control head to the siren amplifier (1751537-02)
The next sections describe how to connect the control head to the network.
Connecting the Active-Low Input Circuits (Cable Assembly 17500308)
Cable assembly 17500308 includes 18-inch, 22 AWG wires for four active-low
circuit inputs. Figure 15 shows the connectors for the four input leads on the
back of the control head. Similar to the siren relay circuits, Inputs 1 to 4 are most
commonly used for circuits that send a signal to the Convergence Network system
when a condition in the vehicle changes. Changes in conditions may include the
opening of a trunk or door, a rise in vehicle temperature, or the release of a gun
lock. The inputs are often used for police vehicle anti-theft devices, intrusion
alarms, and temperature monitoring systems for K9 vehicles.
