Connections for the Ambient Light Sensor
The SSP3000B and SSP2000B both support Federal Signal lightbars equipped with an ambient
light sensor. The software uses
Input 1
to activate functions when the lightbar senses low light.
No extra connections are needed to support this feature. Simply do not connect anything to
Input 1, and make any programming changes you want active during low light on the Input 1
button of the Convergence Configuration Software.
Park Input (Cable Assembly 1751542-01 or 1752542-NY)
The
Park Input
circuit sends a signal to the siren amplifier/relay module to mute all siren
functions except Air Horn and Manual when the vehicle transmission is shifted into park or
neutral. The circuit can detect a +12 V signal or a –GND signal.
IMPORTANT:
The operation of the Park Input circuit can be configured as active high or
active low. The Park Input function is configured through the control head. For instructions, see
“Selecting Active-High Activation of the Park Input Circuit” on page 45.
The
Siren Mute
option is configured with the Convergence Configuration Software.
To wire the Park Input option:
1.
Connect the black Park Input wire from the siren to the electrical circuit that provides
+12 V or –GND when the vehicle transmission is in park (Figure 3.10).
2.
Extend wiring with 18 AWG leads or thicker.
3.
Insulate spliced leads with twist-on wire connectors. Fold and seal unused leads. Use wire
ties and hold-downs for strain relief.
