CCU2EN – 2-Wire EZCOMM Central Control Unit with Ethernet
The CCU2EN is to be installed inside the Traffic Cabinet and is powered by the AC supply mains (115 VAC). The CCU2EN is the power supply and signaling interface between the existing intersection Traffic Control Unit and Navigator Push Button Stations (PBS) which are located in the field. One CCU2EN can control up to 16 EN2 Push Button Stations, 4 maximum per channel. The CCU2EN controls up to four Pedestrian Channels, receiving its timing from the Walk and Don’t Walk signals. Additional advanced configurations can be obtained by utilizing its general purpose inputs. All inputs and outputs have full optical isolation and include transient voltage protection.
PHCU4W – 4-Wire Navigator Ped Head Control Unit
Polara’s 4-Wire Navigator and 4-Wire EZ Communicator Push Button Stations require a control unit in the pedestrian signal head to convert the 120VAC WALK and DON’T WALK signals to isolated low voltage DC signals and DC power. The PHCU4W-M has a separate set of isolated inputs (MUTE) which are used to silence all sounds from the Push ButtonStation. A PHCU4W-M may be used as a direct replacement for a PHCU4W, leaving the MUTE inputs unconnected. The PHCU4W (without Mute) does not have the terminals at the MUTE position and is not capable of performing the Mute function.
XAVCU2 – Control Unit for the XAV2E-LED Push Button Stations
The XAVCU2 is a control unit that works in conjunction with Polara’s XAV2E-LED Push Button Stations and provides a system for playing a voice message at a pedestrian crosswalk where flashing yellow lights are installed.
Note: XAVCU2 model products are not compatible with the previous XAVCU model products.

ECONFIG – EZCOMM Navigator Configurator
The EZCommunicator Navigator Configurator (ECONFIG) is a hand-held remote used for configuring a Navigator 2 Wire System or individual 4 Wire Navigator Push Button Stations (PBS). Just stand a few feet in front of a PBS, point the Configurator at the PBS, turn it on and select your options. The Configurator communicates via infrared with the PBS (and CCU of 2 Wire system). The EConfig is compatible with the N2 and N4 Navigator systems as well as the new EZCommunicator EN2 and EN4 Navigator systems. One Configurator is all you need for maintaining multiple intersections. All of the configuration options in the CCU and PBS are set with the Configurator. The beauty of the Navigator system is its interactive operation. For example, if you select one of the optional Locate Sounds, you hear your choice as you select it. When adjusting volume levels, you hear the level you select. After configuring the features you want, you can upload your choices to just that PBS or to all of the Push Button Stations on the entire intersection with a single button push. The EConfig also has the capability of saving 4 user defined configuration sets and has 3 factory-default configuration sets. (Access is password protected to prevent unauthorized changes.)
A variety of MUTCD & ADA-compliant signage is available depending on your needs and specific applications.
EZ510 – EZCOMM USB Security Box
EZ510 USB Security Box is a small and light weight programming tool with dual USB ports. It may be used with any EZ Communicator product to easily update product software, audio sounds or configuration. The EZ USB Security Box has a “Knockdown” function for emergency situations when audio and configuration files may not be available. With a properly formatted USB Flash Drive, the audio sounds and configuration of an EZ Communicator Push Button Station (EPBS) may be copied to the USB Flash Drive and then downloaded to a second EPBS.
EZ410 – 4-Wire EZCOMM Setup Box
The Setup Box is a special tool which provides a convenient method of operating one or two Polara EZ Communicator 4-Wire Navigator Push Button Station(s) (ENAV4 PBS) in a bench top environment, where they can be setup and tested before installation on the street. The Setup Box simulates the operation of a standard pedestrian signal head with Walk and Don’t Walk signals feeding the ENAV4 PBS.
There are two operating modes. Manual Mode allows push-button control of Walk, Clearance and Don’t Walk intervals. While Automatic Mode cycles continuously through the three intervals.
Connection to the Navigator(s) is made via a 4 position terminal block.
15 Watt External Speaker
The SHX-51 is a patented indoor/outdoor, self-contained, 8 ohm, 15 watt speaker. The full featured speaker consists of a light weight, rust proof, aluminum die-cast housing and dual-action plunger switch for tamper supervision for a normally closed loop.
The SHX-51 series comes completely assembled and ready for installation. It is ideally suited for noisy and busy intersections where high quality and high output sound is required.
ENAV-SB – EZCOMM Sound Baffle
ENAV-SB EZ Communicator Sound Baffle is a small external plastic part used to re-direct the sound from the EZ Communicator resulting in a 10dBA difference between the right side and left side of the unit. It is effective in situations to reduce the sound to the building line while not reducing the sound to the pedestrians in the cross walk.
Installation is easy, the ENAV-SB simply snaps into the speaker grill.
EZ210 – EZCOMM Conflict Tester
The EZCOMM Conflict Tester allows the operator to verify that the internal conflict monitor of the CCU2EN is operating properly. It does this by creating a fault condition in which the CCU2EN should detect and react appropriately to. In addition to the internal Conflict Monitor testing functions, it also has a data monitoring function which allows the user to verify that the CCU2EN is communicating properly with the EZCOMM PBSs.
It is important to understand that transmitting an ENAV or CCU2EN walk code from the Conflict Tester will allow a false walk condition to occur. Because of this, only operators who have thoroughly read and understand the Operating Manual and who are familiar with traffic signal operations should use this tester.
PSM2 – 2-Wire Pedestrian Station Monitor 2
The Ped Station Monitor 2 (PSM2) works in conjunction with Polara’s 2 Wire Navigator system. It is compatible with the EZ Comm 2 Wire Navigator System as well as earlier models. It monitors the status of each Push Button Station (PBS) along with the status of the associated walk light. Its primary function is to detect a walk indication from the PBS in the absence of a walk signal for the corresponding ped phase. As long as no conflict is present, the PSM2 will energize a relay delivering power to the Central Control Unit (CCU). In the event of a conflict, the PSM2 will remove power from the relay which disconnects the power going to the CCU and powers down the Navigator system. The PSM2 will then be locked in a shutdown state indicating the source of the conflict. A manual reset is required to clear the condition.
EZ520 – Colour Pack
The EZ520 Colour Pack is a bundle of the required parts needed to change the Front Cover colour of an EZComm Navigator PBS base unit. This Colour Pack works for both 2 and 4 Wire systems.

EPBS wires are routed inside of the channel to protect them against vandalism. Extender can be bolted or banded to the traffic pole.
NPA4X2-X – Adapter for mounting two 9x12 Navigators on a 4” pole
This adapter is designed to offset two Navigators on a 4” diameter pole so that two 9” x 12” signs can be mounted without conflict. One adapter is needed behind each Navigator. The adapters can either be strapped or bolted to the pole. For bolting, holes are provided to match 6” spacing of most push button signs or spacing for Pelco 5” x 7” frames if these types of frames were previously mounted. Adapter is fully compatible with EZComm Navigators.
Sign Plate Frame Adapters
Polara Engineering’s 9” x 12” and 9” x 15” Push Button Frame Adapters are designed to be attached to Polara’s PBF5X7-X Push Button Frame, for mounting a 9” x 12” or 9” x 15” crosswalk signs. These adapters can also be used on 2 wire and 4 wire Navigators. Their aluminum structure and powder coat finish provides a very strong and attractive mount for crosswalk signs.
2-Wire EZCOMM Cable for 2-Wire Navigator
The Polara 2-Wire EZCOMM Navigator APS System communicates from the Central Control Unit (CCU2EN) to the individual Push Button Stations (EPBS) with digital data over the two low voltage wires. These wires also supply all of the power for the EPBSs.
For optimal performance, Tacel recommends using a 14AWG, Twisted Pair, with a Drain & Shield (Usually a Communication/Data cable or a cable for Loop Detectors). The recommended installation of the cable for most cases (8 EPBS buttons, 2 per channel) is to have both EPBS paired up for the each crossings (including the drain wire) and then having 1 cable per crossing going to the interconnect board in the cabinet. Total of 4 cables going to the interconnect board in the cabinet and to have all 4 drains tied together and grounded in the cabinet.
4-Wire EZCOMM Cable for 4-Wire Navigator
The EZCOMM 4-Wire Push Button Stations (PBS) require a cable to be wired from the PBS to the Ped Head Control Unit (PHCU4W). Which, in turn, is wired to the Ped Head WALK and DON’T WALK lights. A 4 Wire Cable (Belden 8489 or equivalent) must be routed between each EN4 PBS. This cable is not supplied with the EN4 PBS, but is available separately in pre-cut 12 ft. and 25 ft. lengths with both ends stripped.
