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 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. See Figure 9.

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 light bar 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
light bar equipped with an ambient light sensor. To enable light bar dimming with
the ambient light sensor, enable Auto Dim on Relay Input 1 in the Convergence
Configuration Software.
