Chapter 3: Wiring the Convergence Network

Connections for Relay Inputs 1 to 4
Cable assemblies P/N 1751542-01 and P/N 1751542-NY include 18-inch, 20 AWG wires for
four relay circuit inputs. Figure 3.9 shows the connectors for the four input leads on the back
of the amplifier/ relay module.
Inputs 1
to
4
are most commonly used for circuits that send a
signal to the SSP3000B 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.
Input 1
and
2
are active-low inputs that activate when the input pin is pulled to ground.
Input 3
and
4
are active high inputs that activate when the input pin is pulled to +12 Vdc battery voltage
(Figure 3.8).

Software-configurable options include siren activation or siren mute, timer settings, and switch
operation. Extend wiring with 20 AWG leads or thicker. Insulate spliced leads with twist-on wire
connectors. Fold and seal unused leads.
NOTE:
If using a Federal Signal lightbar equipped with an ambient light sensor,
Input 1
is
used to control functions activated by the ambient light sensor. To avoid a malfunction, do not
connect anything to the input wire for
Input 1
when using a lightbar equipped with an ambient
light sensor. To enable lightbar dimming with the ambient light sensor, enable Auto Dim on
Relay
Input 1
in the Convergence Configuration Software.
