HLEMR16 Hazardous Location LED Emergency Light - Class I Div 2

Use HLEMR16 when the project needs emergency illumination in a Class I Division 2 Groups A-D area and does not need an EXIT legend at that location. It is suited to pump rooms, process spaces, industrial corridors, outdoor egress doors, wash-down zones, and utility areas where moisture, corrosion, or classified vapor risk rules out ordinary indoor emergency lights.

• Choose this unit for hazardous-location emergency lighting, not for exit signage.
• Use adjacent exit signs or combo units when the egress plan also needs a visible EXIT legend.
• Confirm the final classified-location rating and group coverage with project documents and the AHJ.

The HLEMR16 rating path is Class I Division 2 Groups A-D, which is different from Division 1 explosion-proof equipment. It should be selected where abnormal-condition vapor exposure matches that rating and the installation method preserves the listed enclosure performance.

• Match Class I Division 2 Groups A-D to the hazardous-area classification on the drawings.
• Do not substitute it for a Class I Division 1 fixture unless the engineer and AHJ approve the change.
• Use the UL 924 and wet-location listing context together with local electrical and life-safety requirements.

Two adjustable 3.3 W MR16 LED heads handle the local egress path while the 7.8 W DC output can extend coverage with compatible remote heads. The PDF lists RHLED-MV, SRHLED, and RHLED16, but notes that RHLED-MV and SRHLED are not Class I Division 2 rated and are for non-hazardous locations only.

• Aim the integral heads toward doors, valves, floor transitions, corridor turns, and equipment paths.
• Keep total remote load at or below 7.8 W and match the 6 V or 12 V output of the selected variant.
• Use RHLED16 or another properly rated remote where the remote head also sits inside the classified area.
• Check wire length, AWG, wattage, voltage, and location rating before using the remote output on long runs.

The electrical package combines 120/277 VAC input, solid-state transfer, NiCd battery backup, magnetic testing, and visible charge/battery indication. SDT variants add automatic monthly, biannual, and annual diagnostic tests for facilities that want easier recordkeeping.

• Select 6 V or 12 V based on the battery platform and remote-head voltage required by the layout.
• Allow about 24 hours for the two-rate charger to restore a discharged battery before full-duration testing.
• Use the magnetic test switch and bi-color indicator during routine inspections without opening the unit.

Mounting details matter because this page is for a sealed hazardous-location emergency unit. The spec sheet calls out die-cast mounting brackets for surface wall mounting and a pre-installed conduit hub for conduit and pendant-mount installation.

• Confirm the wall structure, conduit route, hub orientation, and service clearance before ordering.
• Maintain IP66/NEMA 4X sealing at every penetration and fastener point according to installation instructions.
• Leave room to aim both MR16 heads after the enclosure is mounted and wired.

The enclosure is a product-specific differentiator for HLEMR16: gray fiberglass-reinforced polycarbonate, high-impact UV-stabilized lens, molded gasket, and stainless-steel screws. That package is meant for wet locations, wash-down routines, outdoor exposure, and corrosive industrial surroundings.

• Use the standard product in wet locations from 0 C to 50 C.
• Use the CW option when the site needs -20 C cold-weather support.
• Inspect gasket seating and stainless hardware during maintenance so the enclosure remains sealed.

The live variant set combines voltage with the three main option codes, so the final SKU should be checked against the maintenance plan and installation environment.

• SDT adds self diagnostics with monthly, biannual, and annual tests.
• CW adds an internal heater and battery blanket for cold applications.
• TP adds tamper-proof hardware for public, exposed, or high-abuse locations.
• Combined SKUs are available when the project needs more than one option.

The current product page dimension set is preserved as 16.5 in wide x 6.75 in high x 6.25 in deep. Verify the full dimension sketch in the PDF when coordinating conduit, brackets, head aiming, and service clearance.

• Confirm horizontal clearance around nearby pipes, beams, door frames, or equipment.
• Confirm depth clearance for pendant/conduit entry and lamp-head adjustment.
• Keep the magnetic test area and status indicator visible for inspection rounds.

HLEMR16 is the standalone C1D2 emergency-light unit path. Choose a hazardous exit sign when signage is required, a hazardous combo when the same location needs EXIT legend plus lamp heads, a remote head when the host unit is elsewhere, or a Division 1 explosion-proof emergency light when the classified area requires higher protection.

• HLEMR16: Class I Div 2 emergency illumination with two MR16 heads and 7.8 W remote capacity.
• Hazardous exit sign: EXIT legend only for classified egress routes.
• Hazardous combo: EXIT legend and emergency heads in one sealed fixture.
• Hazardous remote head: extends illumination from a compatible host unit.
• Division 1 explosion-proof emergency light: different rating path for more severe classified areas.

• Verify Class I Division 2 Groups A-D classification, wiring method, conduit sealing, remote-head location rating, and final AHJ acceptance before using HLEMR16 in a classified area.
• Use the CW option for -20 C applications, preserve the IP66/NEMA 4X enclosure seal during mounting, and keep the total remote load within the 7.8 W output at the selected 6 V or 12 V voltage.
