The Traffic Light System consists of a single control unit and several alarm columns. The system is powered by two independents power supplies (230VAC from UPS) and it is fully redundant. Communication between the control unit and columns is based on power line communication technology.
The Control Unit is installed in the ECR, it interfaces with an external alarm system, and has a native support for SRTP (Safe Return To Port). A local interface/indication is available through an Alopex terminal installed on the ECR console. Thanks to the Alopex terminal, it is possible to see the system’s status, to test alarms, and to perform a basic system configuration. The Control Unit allows communication with up to 96 units over different lines, and it is equipped with a local buzzer and sirens. All setup functions are protected by the use of a hardware key.
The alarm columns are engineered for a maximum of 5 module indication, based on led technology visible over 290°. Locally they are equipped with a test push-button for lamp-and sound testing, and with a LED indication for communication activities and power supply. Each column is equipped with fire box protection for cable integrity in the event of fire.
