About Telematics Wireless Products
Telematics Wireless products have been evaluated as Information Technology Equipment (ITE), which
may be installed in Central Offices, Telecommunication Centers, offices, computer rooms, and similar
commercial type indoor or outdoor locations.
Telematics Wireless is an associate member of the TALQ Consortium, and its products are ELEXON
approved. The T-Light™ Wireless Light Control Unit (LCU) is also certified by Intertek.
Description
The T-Light™ Wireless Light Control Unit (LCU) and its communication interface with the T-Light
management software are key components in the Telematics Wireless Smart Lighting System. The LCU is
a wireless control unit installed in one of the following locations:
• On top of the luminaire fixture (External)
• In the luminaire fixture (Internal)
• In the base of the pole (Internal)
The LCU handles the collection and transmission of luminaire data and the execution of commands on the
luminaire from the Smart Lighting System Control Management Software (CMS) via a Data
Communication Unit (DCU) gateway.

Smart Lighting System Overview
The Smart Lighting System collects data from and manages the operation of remote street luminaires. The
System consists of the following components:
• LCU – Located on top of or inside the luminaire cover, or in the light pole, the LCU sends sensor data
and executes scheduled and unscheduled luminaire control commands, such as on/off and dim,
received from the CMS Application Server.
• DCU Gateway – Network gateway between LCU and CMS transmits luminaire data and luminaire
control commands.
• CMS – Web-based backend application server provides real-time management: receives LCU
communications from the DCU and sends luminaire control commands to the DCU for transmission
to LCUs.
CMS usually contains a database of static and dynamic LCU information: ambient light values, lighting
and dimming schedules, power usage, status, etc.

LCU NEMA Galaxy
The LCU NEMA Galaxy is an external luminaire control device which is installed on top of the luminaire
cover into a standard NEMA socket. Control features offer On/Off and dimming level operations.
Monitoring features include identification of lamp and electrical issues and measurement of electrical
parameters.
The LCU NEMA Galaxy uses standard NEMA socket “twist and lock” installation on top of a pole or
luminaire cover, according to ANSI C136.10 and C136.41 specifications.
Standard Features
• Light sensor - Operates as a photocell with the integrated microcontroller and is used as a backup light
control in the event of microcontroller failure.
• Energy meter - Continuous measurement collection and aggregation.
• Integrated RF antenna.
• Over the air firmware updates.
• Each unit is configurable as a repeater, resulting in one additional ‘hop’ from the DCU.
• Real Time Clock (only when connected to the system or when unit received its time zone from the
system and operates with GPS)
• Network data is protected by AES 128 encryption.
• Relay Control for LED driver/ballast power.
• Uses licensed frequency.
• Built in GPS receiver for auto-commissioning
• “Auto Detection and Verification” Software
“Auto Detection and Verification” Software
The LCU NEMA includes the Telematics “Auto Detection and Verification” software that automatically
detects and stores the ballast type (1-10V or DALI) in the LCU. The ballast type is then retrieved during the
commissioning process, thereby eliminating the need to enter it manually into the CMS (auto detection
process also occur each time the power turns on from off state)

Optional Features
• Built-in GPS receiver for full auto-commissioning.
LCU NEMA Supported Data Transfer
With the proper matching of LED driver, the following data information will be provided.
• Current
• Voltage
• Lamp energy (kWh)
• Metered/Active power (Watt)
• Power Factor
• Lamp Burning hours
• LED Driver Temperature (depend on LED driver characteristics)

Installation Requirements
Mandatory Customer-Supplied Equipment
System integrity for the LCU NEMA is ensured with the mandatory installation of customersupplied voltage and current surge protection equipment.
Mandatory Voltage Surge Protection
Warning: To prevent damage due to power network voltage surges, it is
mandatory that you also provide and install a surge protection device to protect
the LCU and the luminaire driver.
Mandatory Current Surge Protection
Warning: To prevent damage due to power network current surges, it is
mandatory that you also provide and install a 10 amp slow-blow fuse or circuit
breaker to protect the LCU and the luminaire driver.
Location
The LCU NEMA is installed on the top surface of the luminaire cover utilizing a standard (twist and
lock) NEMA socket.
13
Post-Installation Commissioning
The serial numbers and GPS coordinates of the LCU NEMA units must be added to the CMS
Equipment Inventory as part of the commissioning process. The level of automation in the
Commissioning process depends on the optional equipment installed in the LCU NEMA:
• GPS – Commissioning is fully automated. Commissioning is complete after the CMS Administrator
executes the relevant command.
• No GPS – Commissioning is a partially manual process:
◦ Installer obtains the GPS coordinates of the LCU NEMA with a handheld GPS device.
◦ Installer records the serial number and GPS coordinates.
◦ CMS Administrator imports the recorded values into the CMS Equipment Inventory, one by
one or by batch.
