Alarms – Optical

Back to Overview

BS 603 / 604

Product Description and Application

The alarms BS 60** are used for generating optical and/or acoustical signals in potentially explosive atmospheres. As flameproof or even intrinsically safe versions they can fulfil various tasks - e. g. in underground mines.

 

• Available as optical, acoustical, opto-acoustical, flameproof and intrinsically safe version
• Available with intrinsically safe control
• Optical part has a light frequency of 1 Hz with xenon photo-flash lamp
• Acoustical part adjustable
• In case of optical alarms: uv-resistant and impact proof - no protective cage required
• Even light distribution
• Four different mains AC voltages available
