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 battery
+12Vdc 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 3.14 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.
