Explosionproof signaling device VSU and VSU-Z

Purpose

They are intended for use as stationary light or light and sound warning means and ensure generation of light and sound signals within explosion hazardous areas of all classes according to the explosion protection marking. When installing on high-rise buildings and pipes located outside air routes, both obstruction lighting fixtures for light marking and warning lights on high-rise and extended facilities can be used.

Features

• The possibility to use both light and light and sound annunciator.
• Use of LED light sources and piezo annunciator allows reducing energy consumption and ensures long service life decreasing expenses for maintenance. Service life for LED light sources achieves 100,000 h.
• Compact piezoelectric element is used as sound source.
• Corrosion-resistant materials with special coating ensure long service life.
• The possibility to double explosionproof signaling devices with fastening on one mounting strip with connection through junction box.

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 lighting fixture body forms explosionproof enclosure with “d” explosion protection type. Grounding bolts М5 are installed inside and outside lighting fixture.

Conversion block and terminal clamps are installed inside lighting fixture.

Signaling device provides two fastening types: ceiling (P) and pendant mounting (V). Depending on fastening transit or radial cable laying is possible.
