Radio Obstruction Light Controller

The Radio Obstruction Light Controller communicates by radio with the obstruction lights.

The controller can monitor & control the lights within a 1000m radius.

The reference obstruction lighting system can include both Low or Medium Intensity obstruction lights, either Single or Double (Twin) types.

Any operation issues or failures can be detected and displayed on the LCD screen.

Possible displayed issues/failures:

• no communication with the lamp
• LEDs or LED driver failure
• obstruction light operating on secondary LEDs (for Double/Twin lights)

The photocell integrated into the front panel detects the ambient light level (day or night). The desired light threshold for switching between Day/Night Mode can be selected using 9 steps (from 100lx to 900lx). The currently running Mode (Day or Night) is displayed on the LCD screen.

The big advantage of using radio communication is that there is no need to run individual cables from every obstruction light in the system to the controller.

• Every 10 seconds, a data request is sent to every lamp in the system.
• The interrogated lamps communicate the status back to the controller (i.e. if there are LED failures or not).
• Every 10 minutes, a synchronization signal is sent to all the lamps in the system in order to keep the flashes synchronized.
• Every 10 minutes, the controller communicates the running Day or Night Mode.
• The operating radio frequency is 868Mhz
