Edwards Signaling 879DEX-G1 Hazardous Location AdaptaHorn, 24VDC, 0.16A AdaptaHorn Grille Type Hazardous Location Horn Diode Polarized
Also known as: 879DEXG1, ED-879DEXG1
The Edwards 878DEX, 879DEX, 888D and 889D Series are diode polarized, heavy-duty, high decibel, vibrating horn signals. They are intended for use in hazardous locations requiring electrical supervision of signaling circuit field wiring. For non-fire alarm applications, horns have a NEMA type 4X rating and may be used outdoors (recommended above temperatures of +25F).
Two mounting brackets are provided on either side of the unit for wall mounting. The housing is tapped on one side for 3/4" (19mm) conduit to allow for field wiring installation.
For use in dusty, hazardous atmospheres where a distinctive, urgent signal is required. Typical applications include use in mines, petroleum plants, gas plants, grain elevators, flour mills, paper mills, textile plants and tankers. |
