G-Series Loudspeakers utilize the latest techniques in non-metallic housing construction to improve corrosion resistance and reduce weight when compared to traditional metal housings. The G-Series Loudspeakers flameproof “Ex d" versions come standard with two (2) M20 entries. The increased safety “Ex de" versions include a separate terminal chamber for quick field termination or pass-through wiring, and includes three (3) M20 entries in a standard configuration. G-Series Loudspeakers are available as 15W devices, and are designed to accept an audio input of either 70 Vrms or 100 Vrms (model-specific). Five (5) remotely selectable tap settings are available at each of the high and low volume settings (user configurable)1. The G-Series Loudspeaker can be combined with all other G-Series audible and visual products in several custom configurations. Custom configurations can be ordered directly from the factory. Optional coupling kits, which allow limited field fixturing, are available.
