Edwards explosion-proof AdaptaHorn signals, catalog numbers 878DEX-N5 and 879DEX-G1, are heavy-duty vibrating horns intended for use where distinctive audible signals are required in a hazardous location having high ambient noise levels. These horns include a series diode and are suitable for use in applications requiring electrical supervision of signaling circuit installation wiring. The 878DEX-N5 is AC powered and the 879DEX-G1 is DC powered. Both AdaptaHorn are listed for installation in the following hazardous locations: Class I, Division 1 and 2, Groups B, C, and D; and class II, Division 1 and 2, Groups E, F, and G, and Class III locations. The horns are in a outdoor type 4X rated enclosure (outdoor type 4X applies to general signaling use in non-fire alarm applications). The AdaptaHorn may be mounted to any solid surface.
