GNExB1X05
Flameproof Xenon Beacons
For use in Flammable Gas and Dust Atmospheres
1) Product Table
Standard
ATEX /
IECEx /
UKEX
*Rate at 1Hz
The table shows the input current taken by the various beacons.
A supply voltage variation of +/-10% outside the voltage range is permissible.
Nominal current at nominal voltage and 1Hz flash rate.
Max. rated current at worst case supply voltage and flash rate.
Table 1: Electrical Ratings.
Ensure the system power supply is capable of providing the maximum current required for all beacons. Review associated cable
size, length and quantity of beacons on each circuit.
2) Warnings
