Description
The explosion-safe signal lights AR-077 have been designed to attract attention in a safe manner in
environments where explosion hazards may exist. For example to indicate a telephone call, indicating the
status of a machine or report a malfunction or hazard that requires immediate action.
The signal light comprises a metal housing with a transparent dome covering the light source. This can be a
flashing or continuous light source. The interior of the transparent dome has light dispersing ribs to
contribute attention of the light beam.
The explosion safety to gas is arranged by the application of protection degree against ignition 'Flameproof
enclosure' in addition to the model with connection terminals protection degree 'increased safety' has been
applied. The explosion safety to dust is arranged by the application of protection degree against ignition
'protection by enclosure'.
The dome is made out of high quality polycarbonate with an exceptionally high impact resistance of more
than 7 Nm. Therefore the dome is not equipped with an extra guard.

a.
