Edwards Signaling continues to make significant updates to it line of high-performance hazardous location signals. For example, the Div. 2 Adaptatone Millennium Electronic Horn produces 27 distinctive tones including high-decibel and soft tones and melodies, without the need for additional tone modules. The 105 Series Div. 2 Non-metallic beacons are for any application where an adverse environment requires marine or NEMA Type 4X-rated visual signal.
