Disc Flasher E864

We regret to inform you that this product is DISCONTINUED; please find our current products here

Designed to provide a highly reliable subsystem for long-term operation in field conditions, the E864 Flasher unit uses the latest surface mount (SMD) and microcontroller technologies to provide a compact, disc-shaped device for the use in lanterns based on 150mm LED Disc Light Sources from the E80x family (E801, E802, E803, E804). It offers several new features required to provide remote monitoring and control capabilities.

The E864 Flasher provides the user with a convenient and flexible setting up by a service computer (a PC with ekta™ Lanserv Plus software) that may be used in both stand-alone and system applications. Special care has been taken to minimise the power consumption of the unit in idle state, which is essential when using the flasher in battery powered buoys.


  Programmable automatic control of flashing
  Daylight-dependent switching on and off of the flashing mode by a photosensor and sending the actual
     switching time messages to the monitoring and control centre
  Autosynchronisation by internal clock/calendar to be adjusted either by GPS receiver or by any other
     flasher in the control and monitoring system
  Built-in monitoring and control LAN interface for the communication with other units
  Sending diagnostic and emergency messages to the monitoring and control centre using a communication
      controller connected to system LAN

  Simple setting up and programming using a service computer with Lanserv Plus software installed
  Built-in A-BUS monitoring and control LAN interface for local data communication
  Built-in temperature sensor allows to maximize the use of accumulator energy and precision long term timing
  Readiness to operate in redundant configurations (primary/secondary flasher)
