IS-B Explosion Proof Intrinsically Safe Beacon

The IS-B Intrinsically Safe LED Beacon has been approved for use in potentially explosive atmospheres for Group I (Mining) & Group II (Above Ground) applications and incorporates a high Ingress Protected IP66 enclosure.

This range is suitable for Fire, Security, Process Control and general signalling applications.

The beacon has a DIP switch that gives the options to change from a 1 Hz (60FPM) flash rate to a static (constantly On) signal.

A specially designed time saver base enables quick and easy installation of this unit with no extra cabling to be made to the head of the unit.

Connections are made to the base during the initial wiring phase which results in a faster more reliable installation. The beacon head simply twists & clicks into the pre-fixed base on commissioning avoiding any additional wiring & connections. Further details can be found on the installation sheet’

This unit must be used in conjunction with an approved Zener Barrier or Galvanic Isolator. See page 2 of the datasheet for further information & ordering details.
