- UL 924 listed, damp-location rated, Title 20 compliant; EM versions provide ~90-minute backup.
Where it shines
- Upscale interiors: lobbies, corridors, retail, hospitality—keep ceilings clean and modern.
- Healthcare/office: even illumination, low profile, easy testing via push-to-test.
- Ceiling-first jobs: recess in drywall or T-bar using the included bar hangers.

Overview: Recessed Edge-Lit Aluminum Exit Sign
Recessed edge-lit signs tuck the housing above the ceiling and illuminate a laser-etched acrylic panel from the edge. You get a crisp, even EXIT legend that appears to float, a slim metal trim at the surface, and none of the bulk of surface-mount boxes. Aluminum construction keeps it light, rigid, and architectural.
Illumination & Panel Choices
- Red or Green LED letters with long life and low energy draw.
- Panel options: clear (most transparent), mirror (bright/reflective), or white (frosted look).
- Single- or double-face; double-face uses a factory mylar backer for equal brightness on both sides.
- Chevron arrows (self-adhesive) and a template are included for clean alignment onsite.
Electrical & Battery Backup
- Dual-voltage input 120/277 VAC; push-to-test and bi-color status LED.
- EM models include a 4.8 V Ni-Cd pack with ≈90-minute emergency runtime; charger restores within ~24 hours.
- Solid-state transfer for instant switchover—no flicker when power drops.
- SPV option accepts 208/220/240 VAC (50/60 Hz) when required.
- Dual-circuit (2C-120/2C-277) available on AC-only units for special power schemes.
Mounting & Trim
- Ceiling recess in drywall or T-bar; bar hangers included for easy placement.
- Detachable trim allows below-ceiling servicing of battery/electronics.
- Finishes: natural aluminum, white, or black powder-coat.
- WM (wall recess) option for corridors that require wall-mounted EXITs.
Code Compliance & Listings
- UL 924 listed for emergency egress; damp-location rated (typ. 0–50 °C).
- Meets NFPA 101, NEC, and OSHA requirements for EXIT signs.
- CEC Title 20 compliant for efficiency.
- Standard characters: 6" height, 3/4" stroke for legibility.
Compare: Recessed vs Alternatives
| Type | Best For | Look & Profile | Install Notes | Watch-outs |
|---|---|---|---|---|
| Recessed Edge-Lit (Aluminum) | Premium interiors; clean ceilings | Floating panel; minimal trim | Requires ceiling cavity; bar hangers included | Cut-out & grid alignment matter |
| Surface Edge-Lit (Thermoplastic) | Value installs; fast retrofit | Slim box + clear panel | Universal canopy; wall/ceiling/end | Visible housing |
| Architectural Surface (Metal) | Design-driven spaces | Metal frame; low profile | Often more finish options | Higher material cost |
| Photoluminescent | No wiring; energy-free | Opaque plate; glows after charge | Verify charging light levels | Not for dim corridors |
Install Steps (Ceiling Recess)
- Layout & cut-out: Mark the opening per template; confirm joists/T-bar spacing and clearance for housing and conduit.
- Set the chassis: Attach bar hangers; secure housing level and square to the corridor sightline.
- Make up power: Pull 120/277 VAC (or SPV) to junction; land conductors; cap unused leads; follow local NEC.
- Battery connect (EM): After constant AC is present, connect the Ni-Cd pack; verify status LED.
- Face & arrows: Install single/double-face panels; apply chevrons with the guide template.
- Trim & test: Snap trim; press push-to-test; document initial pass in the log.
Real-World Scenarios
- Office lobby: Recess the unit in the vestibule ceiling; mirror panel for extra pop under downlights.
- Healthcare corridor: Double-face panel at intersections; SDT option reduces manual testing.
- Hospitality: Black trim against dark ceilings for a barely-there look; chevrons to stair towers.
- Retail: White panel for high contrast in bright ambient light; EM model on mixed circuits.
Myths vs. Facts
- “Recessed installs are slow.” With the right cut-out and bar hangers, they go in quickly and look finished immediately.
- “Edge-lit isn’t bright enough.” Properly specified LED panels with 6"/3⁄4" lettering meet UL 924 visibility.
- “You can’t change arrow direction.” Field chevrons and a template make changes simple at punch-list time.

Frequently Asked Questions
Can I choose red or green letters?
Yes—select the LED legend color during installation. Both meet standard letter size/stroke requirements for visibility.
Will it recess in both drywall and T-bar ceilings?
Yes—bar hangers are included for either substrate; verify clearance and follow the cut-out template.
Does it include battery backup?
Emergency (EM) models include a Ni-Cd pack that provides approximately 90 minutes of illumination during outages.
Is it damp-location rated?
Yes—UL 924 damp listing covers typical indoor humidity ranges (not direct outdoor exposure).
Can I order special wording?
Custom legends are available on request; confirm with your AHJ if alternatives to “EXIT” are acceptable in your jurisdiction.
