Input: Lighting test request
Output: Assigned luminaire test input

Shows the control interface used by the selected self-contained lighting test system.

## In plain English

### What this block does

Shows the control interface used by the selected self-contained lighting test system.

### A simple example

In a switchroom, a normal lighting branch may be switched locally while the specified emergency luminaires remain connected to their own backed-up or integral supply. For this reference, the drawing identifies “Lighting test request” at the input and “Assigned luminaire test input” at the output. Testing method follows the luminaire system documentation.

### What the drawings help you do

Start at the named input: Lighting test request. Identify its source device or document and the state represented on the drawing. Follow the named output: Assigned luminaire test input. Cross-reference its destination and separate the command from confirmation that the equipment responded.

### Terms

- Input: Lighting test request
- Output: Assigned luminaire test input
- Application reference: An explanation of a named drawing function or circuit relationship; the project documents define the equipment and its connections.

## What it represents

Shows the control interface used by the selected self-contained lighting test system. Lighting and access interfaces coordinate the electrical-room service circuits and their supervision. Normal lighting, emergency illumination and access indication have different power sources and purposes.
In a switchroom, a normal lighting branch may be switched locally while the specified emergency luminaires remain connected to their own backed-up or integral supply. For this reference, the drawing identifies “Lighting test request” at the input and “Assigned luminaire test input” at the output. Testing method follows the luminaire system documentation.
Identify the lighting supply type, controlled circuit and the meaning of any test or failure output. A drawing symbol does not establish illumination levels, emergency duration or an approved egress arrangement. The functional block is an independent explanation of this named application. Equipment-specific ratings, terminal connections and operating conditions must be established in the project documentation.

## How to read it

- Start at the named input: Lighting test request. Identify its source device or document and the state represented on the drawing.
- Follow the named output: Assigned luminaire test input. Cross-reference its destination and separate the command from confirmation that the equipment responded.
- Testing method follows the luminaire system documentation.
- Identify the lighting supply type, controlled circuit and the meaning of any test or failure output. A drawing symbol does not establish illumination levels, emergency duration or an approved egress arrangement.

## Information to show or reference

- Label the source and connection reference for lighting test request.
- Identify the destination and defined state of assigned luminaire test input.
- Record the equipment or control-document revision supporting this functional block.
- Check this application limit in the project design: Testing method follows the luminaire system documentation.

## Important distinction

Testing method follows the luminaire system documentation. This reference describes the named application; it does not establish a new IEC graphical symbol, an ANSI device-function number or an exact manufacturer connection diagram.

## Facts

- Representation: Functional block
- Installation focus: Switchrooms
- Input / boundary: Lighting test request
- Output / connection: Assigned luminaire test input
- Lookup label: SETI is a library lookup label, not a standard device designation.
