400EX Die-Cast Aluminum LED Exit Sign with Battery Backup Option

Choose the 400EX when a project needs a rugged architectural die-cast aluminum LED exit sign with a wide option matrix for power, diagnostics, finish, hardware, letter color, and face count. It is best for commercial interiors where metal construction and a low-profile finished look matter more than the lowest-cost thermoplastic option.

• Select red or green LED letters to match building plans, owner standards, and existing building signage.
• Use single-face configuration above doors or wall-backed routes where the sign is viewed from one approach.
• Use double-face configuration at corridor intersections, open areas, or projecting installations with two-way visibility.
• Set chevrons after the final path-of-travel review so arrows match the approved egress route.

• Use AC-only variants where a compliant building emergency source handles runtime outside the sign.
• Use 120 V or 277 V selections for dual-circuit project schedules.
• Use WB Ni-Cd battery variants when the sign itself must provide 90-minute emergency illumination.
• Allow about 24 hours for recharge before full-duration battery testing.
• Use 220-240 V 50 Hz variants where the electrical schedule requires special voltage.

• Universal canopy supports ceiling, end, or wall installation.
• Confirm the junction box, sightline, and mounting orientation before ordering.
• Concealed chevron knockouts let installers configure directional arrows in the field.
• Consider wire guards or protective accessories where carts, public traffic, or abuse risk may affect the sign.

• Brushed aluminum finish supports more architectural door and corridor conditions.
• Black finish options coordinate with darker interiors or contrast-driven design standards.
• White finish options blend with typical walls, ceilings, and frames.
• Die-cast construction and rounded soft-contour design help the sign feel more substantial than commodity plastic signage.

• G2 Guardian self-testing monitors AC, battery, and LED status on eligible configurations.
• TRH tamper-resistant hardware supports schools, public corridors, and other higher-abuse interior routes.
• 2CI1 and 2CI7 options support dual-circuit input where emergency power is supplied separately.
• Review the 400EX PDF before ordering so accessories, wiring, listings, and dimensions are captured together.

• UL 924 listing and damp-location rating support standard indoor commercial egress applications.
• Designed to support NFPA 101, NEC, OSHA, and CEC Title 20 project requirements where applicable.
• 10-year warranty covers housing and electronics; battery coverage is 5-year prorated.
• Document push-to-test, self-test, and full-duration emergency checks according to the maintenance plan.

• Housing measures 12.5 in wide x 8.5 in high x 2.1 in deep.
• Verify clearance around door frames, ceiling features, wall returns, and conduit entries before ordering.
• Confirm final face count, letter color, finish, power source, diagnostics, tamper hardware, and accessories in the project paperwork.

• Choose 400EX when a project needs the broad 402EX/403EX/G402EX/G403EX configuration matrix with battery, diagnostics, and tamper hardware options.
• Choose 400U when the main priority is universal-mount die-cast flexibility with a simpler product path.
• Choose thin or ultra-slim die-cast signs when lower projection and a slimmer profile are more important than the 400EX option set.
• Choose NYC 8 in die-cast exit signs when the project requires larger red letters for New York City compliance.
• Choose wet-location exit signs for exposed exterior, rain, hose-down, or severe moisture conditions.

• Confirm final fixture placement, face count, letter color, finish, power source, diagnostics, tamper hardware, accessories, and local code approval for the project.
