Function and device design

DANGER
Explosion hazard due to improper use! Non-compliance results in severe or fatal injuries.

• Use the device only according to the operating conditions described in these operating instructions.

Function
Product Series YL6S is designed to provide both an audible and visual alarm which can be used to alert, warn or draw attention to machine malfunction/start up or any number of safety related issues. The audible and visual signals can be operated independently or as a combination unit. Corrosion resistance is a key feature of the device which is ideally suited for applications in the harshest of environments both onshore and offshore. The optical element of the device must be regarded as a supplementary alarm indicator when used for alerting/evacuating the occupants of the buildings/structures.

In hazardous areas the devices have explosion protection for ATEX/IECEx Zones 1 & 2 for gas and 21 & 22 for dust. Gas groups covered are IIB & IIC, dust protection for IIIC.

• The device is not intended for continuos use.
• The life of the xenon flash tube is guaranteed for the following number of flashes:
  Variant| Number of flashes
  ---|---
  5 J| 2 million
