An emergency lighting system provides illumination when the normal lighting supply fails. It helps occupants identify escape routes, move through designated areas and locate exits. Depending on the design, emergency luminaires receive backup power from individual batteries or a central emergency supply.
Choosing suitable equipment requires more than selecting a fixture shape. The system must provide the required illumination, operating duration and coverage for the building’s layout and approved safety design.
This guide explains emergency lighting functions, operating modes, product options and the information needed to select equipment for projects in Saudi Arabia.
An emergency lighting system monitors the relevant normal supply and activates its emergency operation when that supply fails.
In a self-contained installation, each emergency luminaire incorporates its own battery and charging equipment. In a centrally supplied installation, compatible luminaires receive emergency power from a separate central source.
The design should identify which supply failures trigger emergency operation. An outage affecting a local lighting circuit may require a response even when power remains available elsewhere in the building.
| System | Backup power arrangement | Selection considerations |
|---|---|---|
| Self-contained | Battery and associated equipment within each luminaire | Individual battery maintenance, charging requirements and test access |
| Centrally supplied | Emergency power provided by a central source | Compatible luminaires, circuit design, central equipment and system monitoring |
The appropriate arrangement depends on project requirements, building size, installation constraints and maintenance strategy.
Emergency lighting functions should be distinguished from luminaire formats.
Escape route lighting illuminates designated routes so occupants can identify the path and negotiate relevant obstacles during a normal lighting failure.
The layout should consider corridors, stairs, changes in direction and level, and other locations identified by the applicable design requirements.
Open area emergency lighting, sometimes called anti-panic lighting, helps occupants orient themselves and move toward escape routes.
A large room does not automatically require a particular fixture style. Coverage depends on emergency light output, optical distribution, mounting height and placement.
Some activities require emergency illumination so people can safely stop a hazardous process or leave the task area.
These applications require a specific assessment of the task, response time and necessary illumination. General emergency fixtures should not be assumed suitable without checking their performance.
Exit signs identify exits and indicate the direction of travel. They complement emergency illumination but do not automatically provide sufficient light across the escape route.
Review Alrouf’s LED emergency exit signs for available product configurations.
These terms describe how the emergency light source operates during normal conditions.
| Operating mode | Normal supply available | Normal supply fails |
|---|---|---|
| Maintained | The light source operates as specified by its normal control arrangement | Continues operating from the emergency supply |
| Non-maintained | The emergency light source remains off | Turns on from the emergency supply |
A maintained fitting can serve normal and emergency lighting functions. A non-maintained fitting provides emergency illumination when required.
Confirm the operating mode of the exact model and how it will be connected. Exit-sign operation should also follow the project’s visibility and safety requirements.
A ceiling mounted emergency light can provide backup illumination from a position on or within the ceiling, depending on the product’s mounting design.
Selection should consider:
Alrouf’s LED emergency ceiling light range includes several models with different specifications.
For a more detailed selection checklist, read how to choose emergency ceiling lighting.
Emergency downlights can provide a compact ceiling installation. Their suitability depends on the beam distribution, emergency output and available mounting arrangement.
Check ceiling cut-out dimensions, installation clearances and access to batteries or associated equipment.
Explore Alrouf LED emergency downlights and confirm the selected model’s installation requirements.
Bulkhead luminaires can be considered where the project needs a robust enclosure or a particular mounting arrangement.
Indoor, outdoor and industrial suitability depends on the exact model’s protection rating, temperature limits, materials and emergency performance.
A bulkhead shape alone does not establish suitability for wet areas, corrosive conditions or hazardous locations.
Twin head units use adjustable lamp heads to direct light toward selected areas.
They may be considered for commercial or industrial spaces where their distribution suits the lighting design. A lighting assessment should verify coverage rather than assume that adjustable heads illuminate an entire room adequately.
Review Alrouf twin head emergency lights for model-specific information.
Exit signs should be selected according to the required legend, viewing distance, direction of travel and mounting position.
Confirm the supplied pictogram, directional arrow and any language requirements against the approved project design. Mounting options and legend choices vary by model.
Use the building layout and safety design to identify escape routes, open areas, exits and any high-risk tasks.
Select equipment for the required function rather than choosing every unit from one product family.
Normal-mode lumens and emergency-mode lumens may differ substantially.
Use emergency photometric data when calculating coverage during a power failure. Normal light output alone is not enough to determine fixture quantity or spacing.
Select a system that meets the project’s required emergency duration.
Do not assume every model provides the same runtime. Verify the rated duration, battery arrangement and relevant operating conditions in the technical documentation.
Assess mounting height, ceiling construction, obstacles, installation clearances and maintenance access.
There is no single installation height or spacing that suits every emergency light. Use the selected fixture’s photometric data and the applicable design criteria.
Choose protection ratings and materials for the actual location.
An industrial application does not automatically require one particular IP rating, and an IP rating alone does not establish hazardous-area suitability. Hazardous locations require separately specified equipment and supporting documentation.
Some models offer automatic testing or monitoring. Others require manual procedures.
Check what each feature tests, how faults are indicated and how results are recorded. Automatic testing does not remove the need to review faults and maintain the system.

For Saudi projects, the responsible designer should establish the applicable requirements and authority approval process.
IEC 60598-2-22 addresses particular requirements for emergency lighting luminaires. Product conformity and the adequacy of an installed system are separate matters: a suitable luminaire must still be selected, positioned and installed correctly.
Request documentation relevant to the proposed models, including:
The IEC publication for emergency lighting luminaires explains the scope of IEC 60598-2-22.
Emergency lighting needs an established inspection, testing and maintenance process.
Follow the applicable project requirements and manufacturer instructions to verify operation, duration and charging performance.
A maintenance programme should include:
Plan tests so that reduced battery charge does not leave occupied areas without the required protection. Allow the specified recharge period after discharge testing.
An emergency light illuminates an area or route during normal lighting failure. An exit sign identifies an exit or direction of travel. Buildings may require both functions.
No. Self-contained luminaires have individual batteries, while compatible centrally supplied luminaires receive power from a central emergency source.
Compare surface-mounted ceiling units and recessed downlights using emergency output, optical distribution, mounting conditions, operating mode and duration.
Review emergency output, duration, operating mode, enclosure protection, temperature limits, mounting options and maintenance access. Confirm that the model suits the location.
The required duration depends on the applicable project requirements. Verify both the required duration and the selected equipment’s rated performance.
No. Results must be reviewed, faults corrected and required records maintained. Inspection and other specified checks remain necessary.
Selecting emergency lighting for a warehouse starts with the building layout and approved emergency lighting design. Storage racks, machinery, loading areas and ceiling heights can affect visibility and light distribution. One fixture type should not automatically be used throughout the building.
Exit signs and emergency illumination perform different functions. An illuminated sign should not be assumed to provide sufficient lighting along the escape route.
Confirm the emergency-mode light output, rated duration, operating mode, battery and recharge information, protection rating, temperature limits and testing method. These characteristics can differ between models within the same product family.
For warehouses with dusty, damp or potentially hazardous areas, ask the responsible engineer to define the installation requirements. Do not assume that every emergency luminaire is suitable for every warehouse location.
