Kidde - Edwards 878DEX-N5 Explosion Proof Horn Strobe 120V

Product Description

The KIDDE - EDWARDS 878DEX-N5 is an explosion proof horn strobe designed for use in hazardous location environments where standard alarm devices cannot safely operate. This unit combines an audible horn with a visible strobe light in a single housing, providing dual-mode alerting in areas where ignitable gases, vapors, or dusts may be present. Operating at 120 volts, it is built to meet the demanding requirements of industrial and commercial facilities. Licensed electricians and fire alarm technicians are the primary installers of this type of device.

The 878DEX-N5 is suited for hazardous classified locations such as petrochemical plants, refineries, paint booths, grain handling facilities, and other industrial environments where explosion proof listed equipment is required by code. Its integrated horn and strobe design reduces the number of individual devices needed at a single notification point, simplifying installation in areas where conduit and housing penetrations must be minimized for safety compliance.

Key Features

• Explosion proof construction rated for hazardous location use
• Combined audible horn and visible strobe notification in one unit
• 120 volt AC operation
• Sold individually as a single unit

Compatibility

Designed as an OEM-style replacement or new-installation horn strobe for explosion proof fire alarm and emergency notification systems in hazardous classified locations.

Installation Notes

Installation must be performed by a licensed electrician or qualified fire alarm technician in accordance with NFPA 70 (NEC) and NFPA 72, including all applicable hazardous location wiring requirements. De-energize the circuit and verify the area is free of ignitable atmosphere before beginning any work. All conduit entries must be sealed with listed explosion proof sealing fittings per applicable code. Do not modify the device housing, as doing so may void the explosion proof rating.
