The TB type Beacon control system is in charge of the supervision, control and indication of anomalies detected in the different Beacon components of the telephony transmission towers.
TB / TB-55 Features:
Control and measurement of the consumption of the two sets of independent ballasts(230 Vac power supply): the main circuit and the reserve circuit. The reserve circuit is connected when there is a fault in the main circuit or when a lamp goes out.
Control inputs of the two twilight photocells on the tower. When the light level is under the threshold, an internal contact is closed (applying a 230 Vac voltage at the input of the photocell of the TB), and the ballasts will be connected. Said photocells are not supplied with the equipment and can be purchased separately.
Alarms indicated with LEDs on the front of the unit.
Alarm signalling relay outputs
Designed to control and supervise the night ballasts on metallic antennae support structures, with a dual Beacon circuit (main and reserve), and to supervise the operation of the dual photocell circuit. Said ballasts will start operating when the level of lighting is below a determined threshold, detected by twilight cells.
