CH900X Surface/Recessed Edge-Lit Exit Sign Overview
The CH900X Chicago-approved edge-lit LED exit sign is built for projects that need a clean acrylic EXIT panel with either surface or recessed mounting. It uses a clear edge-lit panel, 6 in red EXIT letters with 3/4 in stroke, long-life LEDs, and a white architectural housing package for code-driven commercial interiors.
Choose surface models for wall, ceiling, end, or pendant-ready installs, or recessed models when the sign needs to sit flush with the finished ceiling or wall plane. LB models are AC-only; WB models add LiFePO4 battery backup for 90-minute emergency operation. Compare the full Edge-Lit Exit Signs lineup, review Chicago-approved exit signs, or use Recessed Exit Signs when the mounting condition is the main driver.

Best Applications
Choose CH900X for commercial interiors that require a Chicago-approved edge-lit LED exit sign with a clean acrylic panel and red EXIT legend. It fits corridors, lobbies, tenant suites, schools, hotels, public buildings, and finished architectural spaces where a direct-view thermoplastic sign would look too utilitarian.
Surface vs Recessed Selection
- Choose CH900X-S surface models when the sign will mount to a wall, ceiling, end box, or pendant-ready location using the universal canopy.
- Choose CH900X-R recessed models when the sign needs a flush trim appearance in a finished ceiling or wall condition.
- Use recessed hanger bars and the white trim plate for clean alignment with the finished plane.
- Confirm rough-in depth, ceiling conditions, and final viewing direction before selecting surface or recessed mounting.
AC-Only vs Battery Backup
- Choose LB AC-only variants where emergency power is handled by a central inverter, generator, or other approved system.
- Choose WB variants when the fixture needs an integral LiFePO4 battery for 90 minutes of emergency operation.
- Allow the battery to complete its charge period before performing a full-duration emergency test after installation.
- Match the power option to project documents and local AHJ expectations.
Chicago Legend and Panel Checks
- Standard CH900X ships with a red EXIT legend, no arrows, and 6 in letters with 3/4 in stroke.
- Confirm whether the project needs single-face, double-face, arrow, or STAIRS panel options before ordering.
- Use arrow panels when directional egress routing is required by the final layout.
- Keep the acrylic panel clean and unobstructed so the edge-lit legend remains visible from the path of travel.
Mounting and Rough-In Checks
- Surface models support wall, ceiling, end, and pendant-ready mounting with the universal canopy.
- Recessed models include a 20-gauge steel housing, hanger bars, and white trim for flush mounting.
- Confirm junction-box location, conduit entry, above-ceiling space, and sightline clearance before closeout.
- Pendant adapter requirements should be confirmed before rough-in if the sign will hang below the mounting surface.
Electrical and Inspection Checks
- Dual-voltage 120/277 V input supports common commercial electrical systems.
- Protection features include low-voltage disconnect, brownout, overload, and short-circuit protection.
- Push-to-test and the LED status indicator support routine inspection and maintenance checks.
- WB battery models provide 90-minute emergency operation after a full charge.
Options and Accessories
- Current configured SKUs include CH900X-S-LB-WH, CH900X-S-WB-WH, CH900X-R-LB-WH, and CH900X-R-WB-WH.
- Panel options may include EXIT with arrows, double-face panels, and STAIRS panels depending on project requirements.
- S900-PENDANT-ADAPTER can support pendant applications when specified and field installed.
Closeout and Warranty Checks
- Confirm City of Chicago approval, UL 924 listing, legend direction, mounting method, and emergency runtime with the project documents.
- Final fixture placement and acceptance should be confirmed with the local AHJ.
- Warranty coverage is 5 years on electronics and housing, with LiFePO4 battery coverage prorated for 5 years.
Compliance notes
- Confirm City of Chicago approval, UL 924 listing, mounting method, panel direction, emergency runtime, and local AHJ acceptance for the project.
