## Symbol convention

Convention: IEC
Form: Recessed luminaire
IEC 60617 installation-plan style (architectural and topographical installation symbols); independently drawn, not certified IEC geometry or a database identifier.

Plan mark for a recessed ceiling downlight, usually a small circle, sometimes crossed or hatched.

## In plain English

### What does Recessed downlight plan mark mean?

Recessed downlights are drawn as small circles, sometimes with a cross or a filled centre, placed in a regular grid on the reflected ceiling plan. The symbol is distinguished from the general luminaire by size and by the fixture tag.

### A simple example

Downlights need ceiling void depth, fire-rated covers where they penetrate fire-rated ceilings, and clearances from insulation. The plan symbol lets the electrician and builder coordinate these before ceilings close. The symbol does not tell you cut-out size, beam angle or whether the fitting is fire-rated. Those are scheduled.

### What the drawings help you do

Check fire-rated ceiling zones. Read beam angle and cut-out in the schedule. A spotlight is directional and adjustable; a downlight is fixed and points straight down.

## How to read it

- Check fire-rated ceiling zones.
- Read beam angle and cut-out in the schedule.

## Information to show or reference

- Tag fixture type.
- Note fire-rated or insulation-contact requirements.
- Coordinate spacing with ceiling layout.

## Important distinction

A spotlight is directional and adjustable; a downlight is fixed and points straight down.

## Facts

- Graphic form: Small circle on ceiling grid
- Coordination: Ceiling void depth and fire rating
- Exact standard graphic: Not reproduced here; confirm the form against IEC 60617 and the project legend
