The AtlasIED HLE/MLE-30 Polycarbonate Projector Horn is a professional wide-angle horn accessory designed for use with compatible AtlasIED HLE and MLE Series explosion-proof compression drivers. Featuring durable polycarbonate construction and a 120° horizontal × 60° vertical dispersion pattern, the HLE/MLE-30 provides broad sound coverage for industrial paging, voice announcements, and electronic signaling systems in approved hazardous locations.
Engineered for use in demanding industrial environments, the AtlasIED HLE/MLE-30 explosion-proof horn combines the efficiency of a reflex-style projector with wide-angle sound distribution. When paired with an approved AtlasIED compression driver, it helps deliver intelligible voice communication across industrial work areas, processing facilities, and other locations requiring specialized hazardous-area audio equipment.
The HLE/MLE-30 is compatible with several AtlasIED HLE and MLE Series drivers, including the AtlasIED MLE-3T 30W explosion-proof compression driver with integrated 70.7V transformer.
Important: The HLE/MLE-30 is a projector horn accessory only. The explosion-proof compression driver is sold separately. The horn must be used with a manufacturer-approved driver and installed according to the applicable hazardous-location requirements.
Wide-Angle 120° × 60° Sound Coverage
The AtlasIED HLE/MLE-30 features a 120° × 60° dispersion pattern designed to distribute sound over a broad listening area.
Its wide-angle coverage makes it suitable for industrial paging and signaling applications where announcements must reach personnel across large work areas.
The horn's reflex-style projector design provides efficient acoustic output when paired with a compatible compression driver.
The HLE/MLE-30 can be incorporated into properly designed industrial communication systems where speech intelligibility, directional coverage, and dependable operation are important.
Durable Polycarbonate Construction for Industrial Applications
The HLE/MLE-30 is manufactured from polycarbonate, providing a durable and relatively lightweight horn structure for industrial audio installations.
Its construction is intended for use with approved explosion-proof compression driver assemblies in hazardous environments.
The horn's wide dispersion characteristics make it a practical choice for applications requiring broad sound coverage rather than a narrowly focused announcement pattern.
For installations requiring a circular coverage pattern, AtlasIED also offers the compatible HLE/MLE-32 projector horn.
Compatible with AtlasIED HLE and MLE Explosion-Proof Drivers
The HLE/MLE-30 is designed to mount to compatible AtlasIED explosion-proof compression drivers.
Supported driver models include:
-
AtlasIED HLE-1
-
AtlasIED HLE-1T
-
AtlasIED HLE-3
-
AtlasIED HLE-3T
-
AtlasIED MLE-1
-
AtlasIED MLE-1T
-
AtlasIED MLE-3
-
AtlasIED MLE-3T
The HLE/MLE-30 is especially useful when paired with the AtlasIED MLE-3T 30W explosion-proof compression driver, which features a factory-installed 70.7V transformer and selectable power taps.
When combined with the MLE-3T, the HLE/MLE-30 provides a manufacturer-specified sensitivity of 106 dB and a frequency response of 300 Hz to 14 kHz.
These ratings describe the compatible driver-and-horn assembly, not the horn operating independently.
Designed for Hazardous-Location Paging and Signaling Systems
The AtlasIED HLE/MLE-30 is intended for use as part of approved industrial paging and signaling assemblies in classified hazardous locations.
Typical installations may include chemical processing plants, petroleum facilities, industrial manufacturing operations, and other environments where the presence of flammable gases or vapors requires specially rated equipment.
The HLE/MLE-30 and HLE/MLE-32 are the manufacturer-specified projector horns UL Listed for use with compatible AtlasIED HLE and MLE explosion-proof compression drivers.
Safety Notice: Hazardous-location suitability depends on the complete approved driver-and-horn assembly, the applicable location classification, and correct installation. Confirm all requirements with the manufacturer's documentation and qualified installation personnel.
