Medium intensity obstruction light

Medium intensity obstruction light beacon

Medium-lntensity Light Beacon of SAPREM has been designed to warn the air traffic the presence of obstacles.

SAPREM’s Medium lntensity Obstruction Light Beacon uses LED technology and it can be configured to comply with regulations of the lnternational Civil Aviation Organization (ICAO).

  • Luminous intensity (Type A, B, Cmr;:, AB, AC)
  • Flashing Frequency: 20, 30, 40, 60 fpm/li>
  • Beam pattern
  • Twilight sensor
  • Colour

The Light Beacon has a twilight sensor to control the switch on and off, which optimizes the life of the system. Additionally, it uses GPS to synchronize operation using UTC time.

The SAPREM beacon allows networking via RF (868 MHz ) or communication integration via Ethernet. lt is also possible to change its settings and parameters remotely via GSM communication.

SAPREM’s Medium-lntensity Light Beacon works connected to power supplied of 220Vac, but the low power consumption makes it can work with a Stand-Alone System (Solar Module}.

SAPREM supplies ali the elements needed for installation, like solar panels and hardware support. The design of these elements will be suitably dimensioned according to the type and place of installation.
