The Central Server enables remote controlling of an installation, provides a user interface for configuration of the installation, and provides reporting and measurement installation.
The Combox is compulsory to the installation, and monitors a series of Luminaire Controllers, reports status of luminaires to the Central Server via GSM communication, and reports error messages to several mobile phones via SMS communication.
The Luminaire Controller receives instructions from the Combox, performs light programmes and makes measurements at light point level, and contains an astronomical clock for sunset/sunrise-based programming.

Powerline and Radio Frequency

Telea uses the benefits of two data transmission media: powerline and radio frequency, both proven for their reliability and security. In both cases, no dedicated cable is necessary, making it easy to install new installations as well as upgrade existing ones.

Powerline Components (PL)
1 Combox PL, in the switch cabinet (shown here mounted and wired on DIN rails)
2 PL Controller, mounted in the gear tray compartment of the luminaire (LDC shown)
3 PL Controller in column box, located in the fuse compartment of the pole (LSC-BOX shown)

Radio Frequency Components (RF)
4 Combox RF, in the switch cabinet (can also be located elsewhere, within distance to 1st luminaire; shown here mounted and wired on DIN rails)
5 RF Controller, mounted onto the luminaire, in place of a photocell (LSRF shown)
6 RF Controller, mounted inside the luminaire, in place of a minicell (LDRF shown)
