Polara: 3-Wire iNavigator System (iN3)
An iN3 system is designed for intersections where button wires do not exist, though can also be installed on intersections with button wires. A Control Unit installs in each Pedestrian Signal and connects to a PBS via 3 wires. Each system is independent of the others and each PBS responds to the messaging provided by the Pedestrian Signal Head it is connected to. The sounds are not synchronized (unless new Wireless Sync feature is activated), and some of the features on a 2-Wire system are not available. iN3 specific features include:
- Stand alone/Independent System (nothing in cabinet)
- Ped Head Control Unit & Cable provides Walk/DW & Power (24V DC) to Push Button Station
- No ped button wires needed (great for pre-timed/non-actuated systems)
- Terminals are provided to allow actuation (2 button wires to call place calls)
- 3 wire System = Power, Ground, & Data (= reduced wiring in conduits)
- Wireless button-to-button communication provides sound synchronization & remote ped call activation
- Pilot Light Recall feature – turns on pilot light and keeps it on during Clearance & Don’t Walk Cycles
