Product

The AtlasIED HLE-3T is an explosion-proof, UL-listed compression driver developed for paging and notification systems in hazardous hydrogen environments. It combines a 60-watt continuous power rating with a 70V transformer and six available power taps. The driver is designed for use with AtlasIED HLE/MLE-30 and HLE/MLE-32 horns, allowing the horn to be selected according to the installation’s dimensional and dispersion requirements.

Ideal Use Cases

This model is intended for paging and notification applications in hazardous areas where an explosion-proof driver is required. Its stated suitability for hydrogen environments makes it appropriate for projects specifically designed around that operating condition. The HLE-3T can be paired with either an HLE/MLE-30 or HLE/MLE-32 horn, giving system planners two compatible horn options. Because the selected horn determines the final product dimensions and dispersion, the driver can be incorporated into a system after the required coverage characteristics have been established from the applicable horn specifications.

Why Choose This Model

The HLE-3T brings its core electrical and acoustic specifications together in one UL-listed driver. Its transformer provides 2.5, 5, 10, 20, 40, and 60-watt taps at 70.7V, supporting several power settings within a single model. This range lets the driver be assigned an appropriate transformer tap for the planned 70V paging or notification system. A continuous power rating of 60 watts establishes the model’s maximum stated power capability, while the published frequency response and horn-specific sensitivity figures provide concrete information for system planning.

Installation and Integration

The driver mounts to AtlasIED HLE/MLE-30 and HLE/MLE-32 horns. Installers should select the horn before confirming final system dimensions, dispersion, and expected sensitivity, since these details depend on the horn used. With the HLE/MLE-30 horn, the specified sensitivity is 108dB. Pairing the driver with the HLE/MLE-32 horn raises the specified sensitivity to 111dB. The transformer tap should also be selected from the available 2.5, 5, 10, 20, 40, or 60-watt settings at 70.7V according to the system design. No final assembly dimensions or dispersion values are specified for the driver alone; those details should be taken from the chosen horn’s specifications.

Performance Highlights

The HLE-3T has a specified frequency response of 250Hz to 12kHz. Its sensitivity is explicitly tied to the compatible horn: 108dB with the HLE/MLE-30 and 111dB with the HLE/MLE-32. This distinction is important when comparing the two supported configurations because the horn selection changes the published sensitivity figure. The driver is rated for 60 watts continuous and includes transformer taps down to 2.5 watts, providing six stated power choices across the supported 70.7V configuration.

What Makes It Different

The defining combination is its explosion-proof construction, UL listing, 60-watt 70V transformer, and stated application in hydrogen environments. It is purpose-designed as a compression driver for AtlasIED HLE/MLE horn assemblies rather than presented with a single fixed horn configuration. The published specifications identify performance for both compatible horns, making the effect of horn selection clear before installation. The product also carries a warranty period of 60 months from the date of purchase.

Final Assessment

The AtlasIED HLE-3T is a focused choice for hazardous-area paging and notification systems that require an explosion-proof, UL-listed compression driver for hydrogen environments. Its 250Hz to 12kHz response, 60-watt continuous rating, six 70.7V transformer taps, and documented compatibility with two AtlasIED horns provide the essential parameters needed for selection. Final evaluation should account for the intended transformer tap and the dimensions, dispersion, and sensitivity associated with the chosen HLE/MLE-30 or HLE/MLE-32 horn.
