Information About 878DEX-N5
The 878DEX-N5 is part of the Edwards 878DEX Series of vibrating horn signals, built for hazardous location signaling where reliable alarm annunciation is required. The unit features a corrosion-resistant epoxy-coated housing with integrated wall-mount brackets and a 3/4-inch conduit tapping for secure field wiring installation. It is intended for applications such as mines, petroleum facilities, grain elevators, and industrial plants where distinctive warning signals must operate under severe environmental conditions. The horn uses diode-polarized circuitry for electrical supervision and is UL listed for Class I, II, and III hazardous locations while maintaining a NEMA 4X outdoor-rated enclosure.
Key Features:
-
Explosion-Proof Vibrating Horn Output: Provides an urgent high-decibel audible signal for hazardous industrial environments.
-
Diode Polarized Supervised Design: Supports supervised signaling circuits requiring monitored field wiring integrity.
-
120VAC Operating Rating: Designed for 120 Volt AC power systems at 50/60Hz with stable performance.
-
High Sound Intensity Level: Produces approximately 110 dB at 1 meter for effective alarm notification.
-
Corrosion-Resistant Epoxy Housing: Rugged enclosure finished with heat-flowed epoxy coating for harsh locations.
-
Hazardous Location UL Listing: Approved for Class I Div 1 and 2 Groups B, C, D; Class II Groups E, F, G; and Class III sites.
-
NEMA Type 4X Outdoor Enclosure: Suitable for indoor and outdoor installations above recommended ambient temperatures.
-
Wall Mount and Conduit Wiring Support: Includes dual mounting brackets and tapped 3/4-inch conduit entry for installation.
The 878DEX-N5 delivers the reliability and precision required for explosion-proof audible alarm signaling in hazardous industrial and safety-critical facilities.
