2. 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.
2.1 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.

Operating Voltage/Power: 24 VDC / 3W Nom
External Connections:
•2 wires to interconnect board (iN2-ICB) located in the traffic cabinet

3. System Installation
Note, safety protection may be compromised if the iNS2 or iCCU-X2 are either installed or utilized in a
configuration not stated in this manual. Disconnect input power to the iNS2 before field examination.
3.1 iNS2 System Operation During Intersection Flash
The iNS2 APS buttons are designed to cease normal function in the event of intersection flash. When pedestrian walk and
don’t walk signals are absent, the iCCU-X2 firmware suspends normal communication to disable the buttons. For added
safety, we recommend the AC input power for the system be connected such that power to the buttons is
removed during intersection flash. This is especially important when operating in BIU mode, because the
iCCU-S2 will not be signaled via SDLC that the intersection has gone into flash. Not all cabinets have an easily
accessible terminal for AC Line voltage that automatically turns off during flash. The AC Line signal feeding the load
switches would normally qualify. You may need to research your cabinet drawings to determine what is possible.
3.1.1 Wiring the Power Cord
The power cord should be disconnected from the iNS2 system until installation is complete.
To prevent risk of shock, place the intersection in flash to make the following connections:
•Connect the AC Line wire (black or brown) to the terminal with automatic shut-off during flash
•Connect the AC Neutral wire (white or blue) to the cabinet neutral bar
•Connect the Earth Ground wire (green or green/yellow) to the cabinet ground bar
