What are Exit & Emergency Lights?

What are Exit & Emergency Lighting?

Exit & Emergency Lighting is all around us – in our offices, public facilities, commercial properties and etc.… Its presence might not be noticed by many during non-emergency period, but in an emergency situation its presence should be made known to all occupants as it is essential in guiding occupants to safety.

Exit & Emergency lighting is a light fixture with a battery pack that turns on automatically when a building experiences a power failure. 

In the event of an “emergency”, these lights play a significant role in the safety of occupants in a indoor space. In the event of a power failure, emergency lights illuminate – utilizing the power from batteries that are installed inside the fixture – to visually indicate the fastest and safest route for occupants to exit the building.

Importance of Exit & Emergency Lighting

For city dwellers, electricity has become an integral part of everyday life, hence, it’s easy not to think much of it until it becomes unavailable during a power outage or an emergency situation such as a fire outbreak.

Therefore, when occupants experience a sudden shift from an illuminated space to a total blackout, it will definitely cause panic and confusion. This is when exit and emergency lights provide some form of comfort and security.

What is Maintained and Non-maintained mode in Exit & Emergency Light?

What is maintained emergency lighting?

Maintained emergency lighting luminaires are built to be lit continuously and will continue to work in the event of a power failure, although normally at a lower light level. Just like a normal luminaire, when running ordinarily these luminaires will take power from the mains supply, but when they switch to emergency mode they take power from a back up battery. This type of emergency lighting is suitable for public places e.g. hotels, shopping centers and cinemas.

What is non-maintained emergency lighting?

Non-maintained emergency lighting is a luminaire made solely for emergency use. It is designed to only come on in the event of a mains power failure, making sure all emergency exit routes are clearly illuminated. The luminaire will not be active as normal day-to-day lighting and is normally used in workplaces e.g. factories or offices where people are familiar with escape routes. This type of emergency lighting is most common in exit signs and emergency lights.

What is Automated Test System (ATS)?

Automated Test System – An embedded system within Exit & Emergency Light fixtures that conducts functional and duration tests on its own. 

An ATS will indicate if the light fixture is functioning correctly as it is designed to be, if there is any fault detected – such as faulty battery or faulty illuminant (LED) – it will be indicated on the side of the fixture. With this system in place, it reduces the need and frequency to engage certified personnel in conducting tests and checks on exit signs and emergency lights. 

Paragon’s Exit and Emergency Lights, conducts both monthly and annual test.

In its monthly test, ATS will conduct tests on both battery and LED, ensuring it is functioning correctly, while the annual test, ATS will drain the battery completely before recharging to battery’s full capacity and resume its operation.

Therefore, automated testing helps ensure that emergency escape lighting testing is scheduled and carried out in a timely fashion, without disrupting any other electrical services. ATS assist ‘responsible persons’ in managing premises risk, and provides early notification of failures or performance degradation. The tests are to ensure that both battery and LEDs are both ready to operate as intended when the time calls for.

Status indicator with different color of LED will indicate the current status of the equipment.

Which type of Exit & Emergency Light does my building require?

There is no one size fit all solutions when it comes to this, but as a general rule of thumb, all major exits out of an indoor premise and the route leading up to it, should have exit signs guiding occupants to the nearest exit and also illuminating the floor so that occupants can identify if there are any obstacles ahead.
