Flashing beacon / xenon / robust

The BARTEC VODEC VB3 is an ATEX certified visual warning (alarm) device designed to produce regular pulses of high intensity light. The unit is specified for use in the most demanding of applications (which include offshore oil installations and refineries) and provides reliable service in extremes of climate. A robust alloy enclosure resists corrosion risk and will not support organic growths associated with plastic Ex d enclosures. The enclosure is designed without spigot threaded joint which eliminates seizures and eases maintenance.

VB3 has no moving parts and is based upon Xenon gas discharge tube technology, three tubes are fitted each with dedicated firing electronics to ensure highest integrity. Beacon colour is fixed by use of a specifically developed fresnal optic lens which provides both efficient light dispersion and simple field changeable colour assignment. A range of fresnal lens colours are available to assure compliance with worldwide regulations. It should be noted that the connection to the telephone subscriber line is via high integrity optical isolator which eliminates any possible risk of insulation breakdown between high tension flashing beacon electronics and the telephone system. VB3 is also fitted with a high power alarm tone drive output to serve an external explosion proof projector horn. A range of alarm tone signals are generated internally and are user selectable by integral tamper proof switches. External junction boxes are eliminated in all applications of VB3 by provision of up to four M20 gland entries and sufficient discrete terminals to allow cable loop through and connection of all cable screens where fitted.
