Federal Signal G-MSC Global Series® Hazardous Location Custom Fixtures

Quick and easy inter-connecting modular products are the best way to describe the Global Series® product line.

All Federal Signal Global Series fixtures start with the increased safety “Ex de” models and can be combined into a multitude of configurations using two to six devices. The patented connecting system greatly simplifies a user’s installation and wiring experience by requiring only a single explosion-proof wiring gland external to the devices.

G-MSC Global Series® Hazardous Location Custom Fixtures

Two standard configurations are available pre-assembled from the factory: Linear and Parallel. Other custom configurations are available to meet unique project requirements. Refer to individual Global Series data sheets for additional information.
