Flashing Beacon for Use in Hazardous Areas
The BARTEC VB3 ATEX certified (Ex d IIG T3 ATEX certified IP 66) explosion proof flashing beacon is specifically designed to provide reliable, efficient service in hazardous industrial environments.
The unit delivers a massive 30 joules of light energy from multiple xenon gas discharge tubes which is dispersed by a precision developed fresnal optic lens assembly. The fresnal lens is available in a range of colour options including red, blue, white, amber, yellow and green allowing the customer to specify according to service requirements. The fresnal lens and xenon tubes are protected by a toughened bora silicate well glass collar and a rugged stainless steel guard cage. The flashing beacon provides ultimate security enabling safe and continuous use in aggressive applications.
The VB3 provides a number of unique features that are unavailable elsewhere today in a single unit; these include the provision of an integral high power alarm tone generator which is capable of driving an external loudspeaker 7.5Watts rated allowing typical broadcast sound pressure levels in excess of 110dBA. A range of alarm tone cadences are pre programmed into the VB3 and tamper proof switch selections allow the engineer to easily align alarm type versus specification without recourse to manufacturer.
Further features include a telephone ringing detector that automatically controls the flashing beacon/sounder when connected to nominated telephone subscriber instruments. The VB3 is equipped with multiple terminal sets enabling convenient field cable loop -through thereby obviating additional ATEX junction boxes. Cable entry in to the VB3 Beacon is via four M20 isometric gland penetrations; protective earth termination points are provided both on the external and internal sides of the enclosure.
Mains supply input capability is 90-254VAC 50/60Hz. The VB3 weighs just 7kg and is manufactured from corrosion resistant marine grade LM6 alloy which is finished in a high grade, high visibility RAL 2003 paint. Due to no threaded or spigot joints there are no risks of the enclosure parts seizing together during operation. To provide further mechanical integrity all fittings are 316 grade stainless steel minimising maintenance. The VB3 beacon is rated to IP 66 with operational temperature rating of -20 to +60 deg C. The VB3 beacon is the ideal solution to Ex lighting needs.
