Before You Order

Confirm the model number and quantity required before ordering. Verify mounting orientation, required emergency runtime, and compatibility with the existing retrofit housing and control system at the job site.

• Confirm aperture/trim size (5 in square) fits the existing opening or housing.
• Verify required emergency runtime and that the pre-wired emergency configuration meets local code and project specifications.
• Ensure control compatibility for phase or 0–10V dimming with the building’s dimming system.
