Emergency lighting is an essential aspect of building safety. In the event of a power outage, emergency lighting provides illumination to enable safe evacuation of the building. The wiring diagram for emergency lighting is critical to ensure that it operates correctly during an emergency. In this article, we will discuss the wiring diagram for maintained emergency lighting and provide insights on how to install and maintain it efficiently.
What is Maintained Emergency Lighting?
Maintained emergency lighting is the type of emergency lighting that remains on continuously, regardless of whether there is a power outage or not. It is commonly used in high-risk buildings such as hospitals, schools, and public buildings. Maintained emergency lighting ensures that occupants can evacuate a building safely even during a power outage.
Wiring Diagram for Maintained Emergency Lighting
The wiring diagram for maintained emergency lighting consists of several components, including a battery, control gear, and light fittings. The battery is the backup power source that provides power to the emergency lighting during a power outage. Control gear is the component responsible for regulating the power supply to the emergency lighting. Light fittings are the fixtures that provide illumination during an emergency.
| Component | Description |
|---|---|
| Battery | A backup power source that provides power to the emergency lighting during a power outage. |
| Control Gear | The component responsible for regulating the power supply to the emergency lighting. |
| Light Fittings | The fixtures that provide illumination during an emergency. |
The wiring diagram typically consists of a switch to turn the emergency lights on and off, a battery charger to charge the battery continuously, and a control relay to regulate the power supply to the lights. The diagram may also include an automatic testing system that tests the emergency lights periodically to ensure that they are functioning correctly.
How to Install Maintained Emergency Lighting?
The installation of maintained emergency lighting should only be done by a qualified electrician. The installation process involves several steps, including:
- Identifying the areas to install the emergency lighting
- Choosing the right type of emergency light fittings
- Running wiring from the control gear to the light fittings
- Connecting the battery and charger to the control gear
- Testing the system to ensure that it is functioning correctly.
How to Maintain Maintained Emergency Lighting?
Maintaining maintained emergency lighting is essential to ensure that the system functions correctly in the event of an emergency. Some maintenance tasks include:
- Checking the battery for signs of corrosion or damage and replacing it if necessary
- Cleaning the light fittings to ensure that they provide adequate illumination
- Replacing faulty components such as light bulbs or control gear
- Testing the system periodically to ensure that it is functioning correctly.
FAQ
What is Non-Maintained Emergency Lighting?
Non-maintained emergency lighting is the type of emergency lighting that only turns on during a power outage. It is commonly used in low-risk buildings such as residential buildings or small offices.
What is the Difference Between Maintained and Non-Maintained Emergency Lighting?
The key difference between maintained and non-maintained emergency lighting is that maintained emergency lighting remains on continuously, regardless of whether there is a power outage or not. In contrast, non-maintained emergency lighting only turns on during a power outage.
What is the Required Illumination Level for Emergency Lighting?
The required illumination level for emergency lighting is typically 1 lux in the area of evacuation and 0.5 lux for escape routes.
Can I Install Emergency Lighting Myself?
No, the installation of emergency lighting should only be done by a qualified electrician.
How Often Should I Test My Emergency Lighting System?
The emergency lighting system should be tested monthly, and a full functional test should be conducted annually.
In conclusion, emergency lighting is critical to ensuring that buildings are safe during a power outage. The wiring diagram for maintained emergency lighting is essential to ensure that it operates correctly during an emergency. Installation and maintenance of emergency lighting should only be done by a qualified electrician to ensure the safety of the occupants of the building.
