Multisensor detectors for explosion-hazard areas

The multisensor detectors are deployed in explosion-hazard areas of zones 0/1/2 (gas). According to Directive 99/92/EC, these zones are areas in which a hazardous, explosive atmosphere can occur continuously, occasionally or temporarily as a mixture of oxygen and combustible gases, vapors or mist. The multisensor detectors for these areas detect smoke and use the dependable and deception-proof ASA technology (Advanced Signal Analysis) for maximum reliability. All detectors are individually addressed to enable exact localization of an emerging threat – so that response teams can intervene fast and precisely where they are needed.

Safety barrier as an interface

As a coupling element of the Field Device Network (FDnet), the safety barrier is a key component for connecting explosion-hazard areas. The barrier separates the non-threatened zone from explosion-hazard areas. It does not require an external power supply or a connection to the equipotential bonding earth line. It integrates two functions in a single device: the safety barrier and the galvanic coupler, thus reducing the amount of installation work required.

Manual call point for all explosion-hazard areas

A manual call point has been added to the new portfolio for explosion-hazard areas. In addition to the areas in zones 0/1/2 (gas), this detector can also be used in zones 20/21/22 (dust). In these zones, a hazardous, explosive atmosphere in the form of a cloud – made up of combustible dust present in the air – can occur continuously, occasionally or temporarily.
