iNS2 System Description
The iNS2 Accessible Pedestrian System (APS) consists of Push Button Stations (iNS2 PBS) installed on poles with
existing pairs of button wires, and an Intelligent Central Control Unit installed in the traffic cabinet. There are two styles of
iCCU-X2 available. The iCCU-S2 is compatible with all types of traffic cabinets and controllers and is normally placed on a
shelf. The iCCU-C2 is a plug-in card that is compatible only with cabinets that currently use Type 242 Ped Isolators and
have a standard C4 cable connection to the Output File. Each style communicates with the Push Button Stations (PBS)
using digital data over the two low voltage button wires. The buttons are powered by the same wires. This provides a fully
synchronized communication system, with many features.
Note: Hereafter in this manual, when referring to cases that apply equally to both iCCU-S2 and iCCU-C2, iCCU-X2 shall
be used.

iNS2 Accessible Pedestrian Signal Push Button Station (PBS)
The iNS2 is an Accessible Pedestrian Signal Push Button Station (PBS). These PBSs are typically used in pairs, mounted
on poles at each end of a pedestrian crosswalk. Its purpose is to transmit a request for a Walk Signal to a Traffic
Controller by pressing its button, then to provide audible and vibro-tactile feedback to the pedestrian, indicating the current
status of the pedestrian signal. Complete system configuration via Bluetooth may be performed via any PBS in the
system. Similarly, configuration may be performed via Wi-Fi when connected to the iCCU-X2.
