Explosionproof signaling device VSU-M

Purpose

They are intended for use as stationary light warning means and ensure generation of light signals within explosion hazardous areas according to the explosion protection marking. When installing on high-rise buildings, both obstruction lighting fixtures for light marking and warning lights on high-rise and extended facilities in order to ensure safety for aircrafts, for example, airplanes, helicopters, etc. can be used.

Features

• The possibility to use as light annunciator.
• Use of LED light sources allows reducing energy consumption and ensures long service life decreasing expenses for maintenance. Service life for LED light sources achieves 100,000 h.
• Corrosion-resistant materials with special coating ensure long service life.

Design

Signal device consists of aluminum body with yellow powder coating. Protective glass is thermal-resistant, extra strong with high light-transmission capability, fixed inside aluminum ring and screwed on lighting fixture.

The body of LED compartment in signal device forms explosionproof enclosure with “d” explosion protection type, and gland compartments has “е” explosion protection. Grounding bolts М5 are installed inside and outside lighting fixture.

Conversion block and terminal clamps are installed inside lighting fixture.

Signal device has 4 entries with thread М25х1.5 that allows laying cable through transit closed with plug on default.
