One fixture or separate units
Use a combo when one location can satisfy both functions. Use separate fixtures when sign visibility and emergency-head coverage need different positions.
Spec guide
Use these decisions to confirm whether one combo fixture fits the sign, emergency coverage, mounting, and environmental requirements.
Use a combo when one location can satisfy both functions. Use separate fixtures when sign visibility and emergency-head coverage need different positions.
Match wall, ceiling, or end mounting, single- or double-face configuration, arrow direction, and head aiming to the egress path.
Choose red or green, viewing distance, face count, and sightlines according to the project specification and route.
Use wet-location, hazardous, steel, or specialty housings where exposure or abuse exceeds a standard indoor fixture.
Verify battery backup, required runtime, charge/test function, head output, spacing, and product listing.
Final combo selection depends on sign visibility, emergency photometrics, mounting, runtime, product listing, project documents, and local AHJ approval.
Quick answers
Expand the questions that match your application, fixture-selection, or compliance review.
Use a combo when the sign and emergency heads can serve the same location and the project benefits from one fixture, one power connection, and shared maintenance.
Not automatically. The project layout, photometrics, sign visibility, mounting, and AHJ requirements determine whether a combo or separate fixtures are appropriate.
Many do, but verify the selected model's battery, runtime, test function, and listing before ordering.
Use a model specifically listed for wet, damp, exterior, or hazardous conditions and confirm both the sign and emergency-head requirements.
