The LD15 Beacon has been designed for use in potentially explosive atmospheres and harsh environmental conditions. The glass reinforced polyester enclosures are suitable for use offshore or onshore, where light weight combined with corrosion resistance is required.

The safety function of the Beacon is to provide an intermittent or permanent spherical visual warning light when the correct voltage is applied to the unit. The Beacon is designed to operate on a supply voltage of 24vDC with a tolerance of +/- 20%. Under No fault (Normal) Operating conditions the LD15 Beacon will provide a spherical visual warning light when required by the system, with no time delay or other faults Under fault conditions the failure mode of the Beacon is a failure to provide a spherical visual warning light. For the failure rate associated with this failure mode please refer to the table below.

Assessment of Functional Safety This Beacon is intended for use in a safety system conforming to the requirements of IEC61508. Sira Test & certification Ltd has conducted a Failure Modes Effect and Diagnostic Analysis (FMEDA) of the LD15 Xenon Beacon against the requirements of IEC 6150

The results are shown below and are based on Route 1H.

The Beacon is classed as a Type B device
