Installation and Maintenance Instructions

Model G-SND Global Series Sounder

Creating Combination Fixtures in the Field

The Federal Signal Global Series Ex de products can be connected 

together in the field using interchangeable E-box end caps and a 

proprietary coupling system (Figure 1). 

Figure 1 Sounder and sounder combination fixture

The proprietary coupling system allows for simple and cost effective, 

wiring from product to product, often eliminating the need for 

expensive Ex wiring practices and Ex rated glands. The E-box is 

available only when factory installed on an Ex d unit or when used 

as a E-box spacer adjoining an existing E-box. Please refer to the 

accessories listed on page 28 for available options. When creating 

certain fixture combinations, it is necessary to replace E-box end caps 

before mounting the product. If you are creating combination fixtures, 

refer to instruction manual 25500259 for specific instructions and 

details.
