What are maintained emergency lights?
The light remains switched on at all times, both in the event of normal power supply and in the event of a power cut. When the mains power supply is interrupted, it immediately switches to emergency lighting to provide continuous, steady illumination for human life. This type of light is usually used in places where continuous lighting is required, such as theatres, shopping malls or public building corridors, stairwells, lobbies, etc., to ensure ensure that there is adequate lighting for both daily use and emergencies.

 

Maintained emergency lights usage:

When normal power supply, maintained led emergency lights are in constant state and used as general lighting.
In the event of a power failure, maintained led emergency lights automatically switches to battery back-up power supply and continues to provide emergency lighting.
Maintained led emergency lights are suitable for those places where you need to keep bright in both power failure and normal state.

 

How to maintain and care for maintained emergency lights?

Regular Testing: At least once a month, perform a visual inspection to make sure the lights are not damaged or obstructed, and that the signs are legible.
        Monthly Test: A full functional test is conducted once a month, including simulating a power outage to determine if the luminaire's automatic start-up, brightness, and duration meets specifications, usually for a few minutes.
        Annual Test: A comprehensive test conducted once a year to ensure that Maintained Emergency Lights will continue to operate for a specified period of time in the event of a power failure (typically 90 minutes to 3 hours). Requirements vary from country to country.

Parts Replacement: Over time, at least once a year, in-depth maintenance is performed to clean the fixture, replace deteriorated parts, check battery performance, etc.

 

How do I install maintained emergency lights?

Dual Power System: maintained emergency lights need to be connected to both the mains power supply and a battery back-up system to ensure that they automatically switch to emergency lighting mode in the event of a power failure.
Location: Typically installed in escape routes, stairways, evacuation exits and other areas where continuous lighting is required.

 

What is non-maintained emergency Light?
It only activates when the mains power supply is interrupted, which means that the light is switched off under normal conditions and only comes on in an emergency. When the mains power supply is interrupted, the non maintained emergency Light will automatically come on to provide emergency lighting. non maintained emergency luminaires are required to save energy and are often used in places where continuous lighting is not required, such as offices, meeting rooms, warehouses, factories or office environments.

 

How non maintained emergency Light is used:
· When the mains supply is normal, the non maintained emergency Light is switched off and is not used for daily lighting.
· When the mains power supply is lost, the non maintained emergency Light luminaire will automatically activate to provide essential emergency lighting.
· This type of light is more suited to areas that do not require lighting on a daily basis and will only provide a source of light in an emergency.

 

How is the non maintained emergency Light maintained and serviced?

Regular Testing: similar to maintained emergency lights, non maintained emergency lights need to be tested regularly to ensure that they will function properly in an emergency.
        Monthly Test: A 1 to 3 minute test to ensure that the luminaire will start smoothly in the event of a power failure.
        Annual Test: an extended test conducted once a year to ensure that the emergency batteries will support the luminaire during a power outage.
Parts Replacement: Over time, at least once a year, deep maintenance is performed to clean the luminaire, replace deteriorated parts, check battery performance, and more.

 

How do I install a non maintained emergency Light?
· Battery Backup System: The non maintained emergency Light is only connected to the battery backup system and will automatically activate when the main power supply is disconnected.
· Location Options: The non maintained emergency Light is primarily installed in emergency exits or evacuation routes to ensure adequate lighting for evacuation in the event of a power failure.

 

Which of these two types of emergency lighting fixtures to select out of the two?
  Understand the need: Determine your lighting requirements from the type of premise you are in, population density of the area, evacuation exits and the requirement for emergency lighting in case of an emergency.
 Cost budget: In case your initial investment is low but you are ready to incur the cost of the maintenance in a go, then the maintenance emergency lighting will work for you. If potential cost saving over the long term is crucial, maintenance free options should be considered.
  Consider performance: When selecting for emergency lighting, you also have to consider fixture performance and characteristics like illumination, run time, reaction time, temperature and the rest.
 Installation environment: For large facilities where much foot traffic is expected making periodic maintenance inevitable then the luminaires that need to be maintained, should be adopted. For example, if the space is small, like an office, a house, or if it is impossible to regularly maintain light access, then no-maintenance light will be more suitable.
  Compliance: As a result, as a commercial and residential property owner, your area of residence may require you to install emergency lighting. Ensure that any lighting that has been chosen meets with the required legal requirements!
 Consult a professional: In case the selection of an emergency lighting is troubling to you, you can speak to one of our Emtrons emergency lighting experts who will guide you depending on the characteristics of your building.
