Features

Federal Signal patented G-MSC Global Series®  Dual Models allows two audible or visual devices to be combined as one complete assembly. This dual model offers a common increased safety “Ex de” field wiring chamber which greatly simplifies the installation and wiring of two signals. The dual signal can be surface mounted or mounted with an optional ratchet adjustable stainless steel mounting U-bracket. 
Either of the devices can be wired to function independently or in tandem1. Two like devices can also be combined to support a redundant alerting system, simplifying installation of A/B redundant systems.
