When a power failure occurs, identifying the correct emergency exit route quickly is critical for safe building evacuation. LED Emergency Exit Signs provide illuminated directional guidance to help occupants locate emergency exits in commercial, public, and industrial facilities.
Unlike standard illuminated signs, emergency exit signs are designed to remain visible when normal power is interrupted. Depending on the model, they can provide emergency operation for approximately 3 hours, with different viewing distances, mounting configurations, operating modes, and protection ratings available for different applications.
Al Rouf Lighting Technology offers several LED Emergency Exit Sign model groups designed around different installation and visibility requirements.
LED Emergency Exit Signs are illuminated safety signs used to identify and indicate the direction of emergency exits during normal operation and power failures.
They are commonly installed in:
The sign's effectiveness depends on several factors, including viewing distance, mounting position, legend direction, emergency duration, and the environmental conditions of the installation area.
For projects where emergency lighting is required throughout a building, exit signs are normally considered alongside other emergency lighting solutions to create a complete emergency lighting system.
An LED emergency exit sign normally operates from the building's AC power supply during normal conditions while maintaining a rechargeable battery system for emergency operation.
When normal power is interrupted, the internal battery provides power to the LED light source so the exit sign remains illuminated.
The Al Rouf emergency exit sign catalogue includes models with an emergency duration of approximately 180 minutes (3 hours). Battery and recharge specifications vary between model groups.
For example:
The catalogue shows 16-hour and 24-hour recharge options depending on the model group.
The right emergency exit sign depends on the required viewing distance, mounting method, protection level, and operating mode.
The Al Rouf range includes several model groups documented in the emergency lighting catalogue.
These models provide:
The catalogue lists different emergency luminance flux levels for these models, which can affect the visibility of the sign depending on the installation and viewing conditions.
These models are particularly relevant when a project requires a higher level of ingress protection, such as IP65.
This model group provides two different viewing-distance options:
Both models support maintained/non-maintained operation and provide approximately 180 minutes of emergency duration.
The BY-B2108E-S24L is specified with a 24 m viewing distance, while the BY-B2108E-S32L is specified with a 32 m viewing distance. Both models are IP40 and include auto-test functionality. The battery capacity differs between the two models.
This makes viewing distance an important consideration when selecting an exit sign for a particular corridor or building layout.
The BY-B2415I20 and BY-B2415I21 models provide another configuration for emergency exit signage.
The catalogue specifies:
These models also support wall, ceiling, hanging, and recessed mounting configurations, depending on the installation requirements shown in the catalogue.
Viewing distance is one of the most important factors when selecting an LED Emergency Exit Sign.
The Al Rouf range includes models specified for 24 m and 32 m viewing distances.
A 24 m model may be suitable when the required viewing distance is relatively shorter.
A 32 m model provides a greater specified viewing distance and can be considered when the building layout requires the sign to remain identifiable from farther away.
However, viewing distance should not be considered in isolation. Mounting height, corridor configuration, sign orientation, and light distribution can also influence practical visibility.
The product catalogue includes light distribution curves for the different model groups, demonstrating that optical performance differs between models.
Emergency exit signs can be installed in different positions depending on the architectural design and evacuation route.
The Al Rouf range includes several mounting configurations:
The BY-B2108E range, for example, is illustrated with side, hanging, wall, and ceiling mounting configurations in the catalogue.
Choosing the correct mounting configuration helps ensure that the sign is positioned clearly within the intended line of sight.
The legend communicates the required evacuation direction to building occupants.
Depending on the model and project requirements, available configurations can include:
The catalogue also shows multiple directional patterns for the BY-B2108E models, including different arrow directions and customizable patterns.
This flexibility can be useful for projects where exit signage needs to correspond to a specific evacuation route.
The IP rating indicates the level of protection provided against the ingress of solid particles and water.
The Al Rouf LED Emergency Exit Sign range includes different protection levels depending on the model:
For example, the BY-B2036E, BY-B2136E, and BY-B2236E models are specified with IP65 protection, while the BY-B2108E models are specified with IP40, and the BY-B2415I20 and BY-B2415I21 models with IP20.
Therefore, the required IP rating should be selected according to the actual installation environment rather than assuming that every emergency exit sign requires the same protection level.
Another important consideration is the operating mode.
A maintained exit sign remains illuminated during normal operation and continues to provide illumination during an emergency power failure.
This configuration can be appropriate when continuous exit identification is required.
A non-maintained exit sign is normally activated for emergency operation when the regular power supply fails.
The Al Rouf catalogue lists maintained/non-maintained operation for several models, while the BY-B2415I20 and BY-B2415I21 models are specified as maintained.
The required operating mode should therefore be selected according to the project's emergency lighting design.
Some LED Emergency Exit Sign models include an auto-test function.
Auto-test functionality can help verify the condition and operation of the emergency lighting system without relying entirely on manual testing.
The BY-B2036E, BY-B2136E, and BY-B2236E models include auto-test functionality, as do the BY-B2108E and BY-B2415I20/BY-B2415I21 model groups shown in the catalogue.
When specifying an LED Emergency Exit Sign, engineers, consultants, contractors, and project owners should consider the following:
Check whether the project requires a 24 m or 32 m viewing distance.
Determine whether the sign will be:
Determine whether the project requires maintained or non-maintained operation.
Select the appropriate IP rating based on the installation environment, with available options including IP20, IP40, and IP65.
The documented Al Rouf models provide approximately 3 hours of emergency operation, although battery and electrical specifications vary by model.
Choose the required exit direction, language, and legend configuration based on the evacuation plan.
Before specifying a model, review its:
Emergency exit signage is one part of a broader emergency lighting strategy.
For commercial and industrial projects, the selected system should consider exit identification, emergency illumination, mounting position, environmental conditions, viewing distance, and emergency operating duration together.
