Explosive environments detectors (Ex)

Why explosive environments detectors?

Explosive environment detectors from Siemens protect people and assets in explosion-vulnerable areas with fast, reliable fire detection. Chemical, pharmaceutical and gas distribution plants as well as oil refineries, pipelines and other installations require fire protection that is robust enough to withstand adverse environments while sensitive enough to detect even a hint of fire. Reliable detection that can trigger an early and genuine alarm prevents unnecessary downtime and the costs caused by false alarms.

Galvanically isolated Line Adapter (Ex) and the unique ASAtechnology from Siemens make the addressable multi-sensor detectors a technically superior product and an ideal choice for gas zones 0, 1 and 2.

Key benefits

Maximize safety

Maximize safety and uptime in hazardous areas with fast, reliable detection that reduces false alarms, avoids unnecessary shutdowns and protects people, assets and processes in gas zones 0, 1 and 2 and dust zones 20, 21 and 22.

Reduce costs and complexity

Cut installation effort and lifecycle costs by using one Line Adapter (Ex) as galvanic isolator and translator. It saves space, speeds wiring and connects up to 31 devices, including Ex detectors and call points on each line.

Modernize systems stepwise

Modernize existing fire systems step by step. Addressable Ex detectors can also run in collective mode, making it easy to upgrade or extend legacy installations with the latest technology.

Featured capabilities

Advanced Ex detection with ASAtechnology

An addressable multi-sensor Ex detector with ASAtechnology interprets sensor signals in real time, applies application-specific parameter sets and stays immune to deceptive phenomena such as steam or dust.

Space-saving Line Adapter (Ex)

The Line Adapter (Ex) combines galvanic isolation and translation in one compact module, supports up to 31 devices per line, includes an integrated turbo isolator, and requires no earth ground connection.

Comprehensive VdS-approved Ex portf

A VdS-tested Ex portfolio covers gas zones 0, 1 and 2, with manual call points approved for dust zones 20, 21 and 22, giving a single, compliant solution for a wide range of hazardous-area applications.
