Connections for the Ambient Light Sensor
The SSP3000B and SSP2000B both support Federal Signal light bars equipped
with an ambient light sensor. The software uses Input 1 to activate functions when
the light bar 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 44.
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
pr12 V or –GND when the vehicle transmission is in park. See Figure 11.
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.
