W2H series signaling devices are used as independent audible signal or warning devices. W2H are seen in Class I, Division 2, Groups A,B,C,D hazardous areas where flammable vapors or gases may be present due to accidental or abnormal operation. W2H are also used in Class II, Division 2, Group G hazardous areas where combustible dusts may be present due to accidental or abnormal operation. The W2H is a solid‑state, compact, rugged but lightweight. The system is programmable, which allows the convenience of tone selection, without the need for separate tone modules. Each unit can be programmed for any one of four different tones (whoop, wail, hi‑lo and horn), by wiring to the corresponding terminal on the unit's terminal strip. Unit may be field wired for multiple signal selection by manual or automatic control. 180 degree speaker rotation allows flexibility in direction of sound. Corrosion resistant conformal coating protects the printed circuit and other interior components.
