Explosion-Proof Edge-Lit LED Exit Sign - Class I Div 1

Explosion Proof Edge-Lit Exit Sign - CP-EXP, Class I Div 1 / Zone 1, UL 924

The CP-EXP explosion proof edge-lit exit sign is the Class I Division 1 hazardous-location path for projects that need an edge-lit EXIT sign inside classified industrial, utility, marine, or process areas. The factory-sealed, copper-free cast-aluminum housing protects the acrylic legend assembly in Class I Division 1 Groups C-D, Class II Division 1 Groups E-G, Class III, and Class I Zone 1 IIA/IIB locations.

Configure CP-EXP with red or green LED letters, single-face or double-face viewing, AC-only or 180-minute Ni-Cd battery backup, optional G1 self diagnostics, and either WP wall/pendant installation or EB end-bracket installation. It is IP65 rated, uses a T6 temperature class, supports standard 120/277 VAC input, and is made in the USA for BAA-sensitive project submittals.

Best For

Use CP-EXP for Class I Div 1 and Zone 1 egress signage in petroleum facilities, chemical processing areas, fuel-transfer rooms, paint and solvent environments, offshore or marine-adjacent utility spaces, and other classified areas where the approved drawings call for Division 1 equipment instead of a standard wet-location or Division 2 exit sign.

Key Features

• UL 924 listed explosion proof edge-lit LED exit sign with 100 ft viewing distance.
• Hazardous ratings include C1D1 Groups C-D, C2D1 Groups E-G, Class III, and C1 Zone 1 IIA/IIB; Zone 2 coverage includes IIA, IIB + H₂, and IIC.
• CP-EXP uses a factory-sealed copper-free aluminum casting with IP65 sealing for washdown, wet, damp, marine-air, and coastal Division 1 environments.
• Select red or green LEDs behind the edge-lit acrylic panel; 6" letters, 3/4" stroke, field chevrons, and the double-face insert support the egress plan.
• Choose LB for AC service or WB when the sign itself must supply the 180-minute emergency runtime.
• Standard dual-primary 120/277 VAC input; 240T appears as a spec-sheet option for 220-240 VAC projects that require quote support.
• WB assemblies add brownout safeguards, low-voltage disconnect, push-to-test hardware, and roughly a 24-hour recovery charge.
• G1 versions add automatic self-test logic for facilities that document inspection cycles.
• WP configurations support wall or pendant installation; EB configurations support end-bracket installation.
• Standard 1/2" NPT conduit hubs on top and sides support classified-area wiring layouts.
• Domestic manufacturing supports Made-in-USA and Buy America submittal packages.

Illumination

• The clear edge-lit panel is illuminated by red or green LED packages for a crisp EXIT legend in classified rooms.
• Six-inch characters with a 3/4" stroke are built for the 100 ft viewing distance expected on egress plans.
• Field-selectable chevrons support directional arrows, and the included white insert supports double-face viewing where required.

Electrical

• Ships for 120/277 VAC, 60 Hz dual-primary circuits common to industrial egress projects.
• LB SKUs run from normal AC power where the backup source is remote or omitted by design.
• WB SKUs carry the onboard Ni-Cd pack for a 180-minute emergency cycle.
• Add G1 to have the battery unit run scheduled diagnostic tests.
• Battery-equipped units include brownout sensing, low-voltage disconnect, push-to-test, and about a 24-hour recharge window.

Installation & Face Setup

• WP: wall or pendant configuration for surface-mounted classified-area conduit layouts.
• EB: end-bracket layout for corridors, equipment rooms, or doorway approaches that need the sign projected into view.
• Single-face: specify for one-direction approach paths or above-door placements.
• Double-face: specify where occupants approach from two directions; the mirror insert is included for the second legend face.
• Confirm conduit entry, orientation, face count, arrow direction, and classified-area acceptance with the project engineer or AHJ.

Housing / Hazardous-Location Body

• The factory-sealed copper-free cast housing shields the LED and battery electronics inside classified industrial spaces.
• IP65 sealing plus salt-spray testing make CP-EXP a fit for washdown zones, marine-adjacent rooms, damp corridors, and coastal facilities.
• A clear acrylic legend panel and gray industrial finish keep the assembly practical for utility, processing, and plant egress routes.

Options & Accessories

• Letter color: choose red CP-EXP or green GCP-EXP configurations to match the project standard.
• Face count: choose single-face or double-face by selected SKU.
• Power source: select LB for normal AC operation or WB for onboard 180-minute emergency backup.
• Self diagnostics: select G1 when the facility wants automatic test support.
• Installation path: choose WP for wall/pendant layouts or EB for end-bracket projection.
• Special variants: verify any 240T voltage or EU running-man legend requirement before quoting because those options are not part of the current live 24-variant set.

Certifications / Warranty

• UL 924 listed for classified-location egress signage, with the final NEC, NFPA 70, NFPA 101, and OSHA fit confirmed during project specification.
• Hazardous-location ratings include Class I Div 1 Groups C-D, Class II Div 1 Groups E-G, Class III, and Class I Zone 1 IIA/IIB; temperature class T6 equals 85 deg C maximum surface temperature.
• 5-year warranty on electronics and housing; Ni-Cd battery coverage is 5-year prorated.

Dimensions

• Housing: 14.9" W x 16.0" H x 3.7" D

CP-EXP vs Alternatives

Choose CP-EXP when the project calls for a Class I Div 1 or Zone 1 explosion proof edge-lit exit sign with IP65 cast-aluminum construction. Choose CP-E when the location is Division 2/Class II/Class III only, a standard wet-location exit sign when the area is wet but not classified, or a standard edge-lit exit sign for ordinary indoor architectural spaces.
