Programmable Input Circuits
Pathway has connections for four general-purpose input circuits, plus dedicated
inputs for park, horn and igniton. The inputs are most commonly used for switches
that send a signal to the siren when a condition in the vehicle changes.
LED Indicators and Visual Diagnostics
All buttons on the control head glow when the system is on. Pressed buttons
turn bright to indicate that the function they control is active. The buttons are
programmable for red or blue backlighting. LEDs on the keypad mimic these active
SignalMaster patterns: Left, Right, Center-Out, and Warn. An LED glows over the
position in which the slide switch is placed. Diagnostic LEDs for speaker fault
detection are also available and are programmable.
