This 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.

All MTL7700 Series barriers are based on the same simple principle. Each channel contains two stages of pulse-tested Zener or forward connected diodes and an ‘infallible’ terminating resistor. In the event of an electrical fault in the safe area, the diodes limit the voltage that can reach the hazardous area and the resistor limits the current. A fuse protects the diodes, and the two stages of voltage limitation ensure continued safety if either stage should fail. No active output current limiting circuits are employed. All models are certified ‘ia’ for all zones and ‘IIC’ for all explosive atmospheres (except MTL7707P+ and MTL7729P+, 'ia' 'IIB').
