UL Listed Explosion-Proof 16.5 inch Diameter Horn

Ideal Use Cases

The AtlasIED HLE/MLE-32 is a UL listed, 16.5-inch-diameter horn intended for paging applications where an explosion-proof design is required. It is designed for use with specified AtlasIED HLE and MLE compression drivers and has a published dispersion of 95 degrees. This combination makes the model appropriate for paging-system plans that specifically call for the HLE/MLE-32, one of its listed drivers, and a defined coverage angle. It can be considered for a new compatible paging assembly or for work involving the named HLE and MLE driver families. Selection should remain tied to the stated application, driver list, dimensions, and UL-listed explosion-proof description rather than to unlisted environmental or acoustic ratings.

Why Choose This Model

The supplied specifications identify exactly which compression drivers the horn mounts. Supported HLE models are HLE-1, HLE-1T, HLE-3, and HLE-3T. Supported MLE models are MLE-1, MLE-1T, MLE-3, and MLE-3T. This precise list allows compatibility to be checked by model number instead of assumed from appearance or diameter. No compatibility beyond these eight drivers is stated. The HLE/MLE-32 also carries a warranty period of 60 months from the date of purchase. Together, its UL listing, explosion-proof design, documented dispersion, defined physical size, and driver compatibility provide concrete criteria for product selection.

Installation and Integration

Plan installation clearance around the published 16.5-inch diameter, equivalent to 416 mm, and the 17.5-inch depth, equivalent to 445 mm. The diameter is expressly specified with the driver, so it should be treated as an assembled measurement when planning available space. Product imagery identifies the driver as sold separately. Select one of the listed HLE or MLE compression drivers and verify its exact model before completing the system configuration. The supplied data does not state the mounting hardware, connection method, wiring requirements, weight, voltage, or installation orientation, so those details should not be inferred from the horn dimensions. Use the published 95-degree dispersion when planning coverage and integrating the horn into the paging layout.

Performance Highlights

The principal published coverage specification is 95-degree dispersion. This is the key acoustic planning value provided for the horn and defines the stated coverage angle for paging-system design. The horn is intended to operate with a compatible AtlasIED HLE or MLE compression driver; the source does not provide standalone output specifications. Frequency response, power handling, impedance, sensitivity, maximum sound-pressure level, and bandwidth are not listed. Those values should therefore be determined from the selected compatible driver and complete system documentation rather than estimated from the horn's physical size. The stated diameter and depth are useful for fit and clearance planning, but they do not establish output capability.

What Makes It Different

The HLE/MLE-32 is defined by more than its 16.5-inch diameter. Its distinguishing details are the UL listing, the explosion-proof design required for its stated paging application, the 95-degree dispersion, and compatibility spanning eight named drivers in the AtlasIED HLE and MLE families. The compatibility range includes the HLE-1, HLE-1T, HLE-3, HLE-3T, MLE-1, MLE-1T, MLE-3, and MLE-3T. This model-specific integration information reduces uncertainty when the paging design already uses one of those drivers. The 60-month warranty period also supplies a clearly defined term measured from the original purchase date.

Final Assessment

For a paging project that specifies a UL listed horn with an explosion-proof design, the AtlasIED HLE/MLE-32 presents a clearly bounded selection profile. Its documented attributes include a 16.5-inch diameter with driver, a 17.5-inch depth, 95-degree dispersion, compatibility with eight HLE and MLE compression drivers, and a 60-month warranty from the date of purchase. Confirm that the selected driver is one of the listed models and allow for the complete published dimensions during installation planning. If the project requires acoustic, electrical, mounting, or environmental figures beyond those supplied here, those values must be confirmed separately. Within the available specifications, the model's strongest attributes are its precise driver compatibility, defined coverage angle, UL listing, and stated explosion-proof paging application.
