APPLICATIONS

Install HLE or MLE Series loudspeakers to efficiently and safely communicate in combustible and dust-filled areas. All drivers comply with the regulations governing electrical equipment at hazardous locations as set forth by the National Electric Code. Drivers are listed by UL and CSA (HLE Series only). They are recommended for paging, signal and voice communication in chemical processing, petroleum, natural resource exploration and atmospheres as listed in the chart below.

GENERAL DESCRIPTION

Series HLE and MLE loudspeakers are explosion-proof compression driver/horn assemblies engineered for high-efficiency voice and electronic signal communication in hazardous areas. Drivers, which are protected within a rugged die-cast aluminum housing, are available in

60-watt (HLE Series) and 30-watt (MLE Series) power handling versions. Models with T suf- fix include a factory-installed, internally mounted transformer (Note: To meet UL requirements transformer must be factory installed). All models are equipped with 12" conduit access and an adjustable mounting bracket.

Projector horns are available in two styles to meet dispersion requirements. Model HLE/MLE- 30 is a high-quality, polycarbonate projector that creates a 120 ° x 60 ° pattern for wide area coverage. Model HLE/MLE-32 is a spun aluminum bell providing a 95 ° circular distribution emphasis.

Note: – For Canadian use (Price List page 17 Text)

Drivers and projector horns are ordered and shipped separately. For performance accuracy, specifications are listed for assembled configurations.
