YodalightEx YL4IS — Intrinsically Safe Sounder Beacon

The Yodal EX YL4IS is an intrinsically safe combined audible and visual signal designed for hazardous environments, delivering up to 100dB at 1 metre alongside an 8-LED flashing beacon. It can be powered from a combined supply through a single barrier, or the sounder and beacon can be wired independently, for flexible room or zone coverage.

With 32 selectable tones, stainless-steel fixings and a monitoring facility, it is ATEX certified for zones 0, 1 and 2 (and dust zones). Must be used with an approved Zener Barrier or Galvanic Isolator.

Combined certified audible-visual signalling for hazardous areas.

IMPORTANT! This product must be used with an approved Zener Barrier or Galvanic Isolator. All connections into the product must be made via a suitably rated barrier or isolator — never connect it directly to the voltage supply without a barrier in place, as this will cause permanent damage to the PCB and void the warranty. Installation and connection should only be carried out by appropriately competent and qualified personnel.
