What is emergency lighting?

Emergency lighting is lighting provided in the event of an emergency situation where a loss of power results in the failure of the normal illumination.

The loss of power to the normal illumination could occur due to fire or a power cut.  This could potentially lead to sudden darkness and pose a potential danger to the occupants of the building.

Emergency lighting is required to operate fully automatically and give illumination of a sufficiently high level to enable all occupants to evacuate the premises safely. Most new buildings now have emergency lighting installed during construction; the design and type of equipment being specified by the architect in accordance with current Building Regulations and any local authority requirements.

The British Standard provides the emergency lighting designer with clear guidelines to work to. BS 5266-1: 2011 embraces residential hotels, clubs, hospitals, nursing homes, schools and colleges, licensed premises, offices, museums, shops, multi-storey dwellings, etc.

Although this standard recommends the types and durations of emergency lighting systems relating to each category of premises, it should be remembered that the standards are the minimum safety standards for these types of building and that a higher standard may be required for a particular installation.

Emergency Lighting is a general term which can be split into five main distinctions.  

1) Emergency Escape Lighting is the lighting which provides sufficient illumination so that all occupants can evacuate in the event of an emergency situation, or attempt to terminate any potentially dangerous processes before evacuation.  Emergency Escape Lighting is part of the fire safety provision of a building and a requirement of The Regulatory Reform (Fire Safety) Order 2005.

2) Standby lighting is lighting which enables normal activities to continue substantially unchanged.  We won't cover standby lighting much more than this, as it is not a legal requirement and is a feature which may or may not be needed, and is dependant on the use of the premises.

3) Escape Route Lighting is lighting which ensures the means of escape can easily be identified.

4) Open Are or Anti-Panic lighting is part of the escape lighting system and provides enough illumination to allow occupants to reach an area where the means of escape can be identified.

5) High-risk Task area lighting is lighting which will provide sufficient illumination so that an operator can terminate a potentially dangerous process or carry out proper shut-down procedures before evacuating the premises.


Does Lux Intelligent control my emergency light system?

No.  Lux Intelligent is purely an Emergency Light Testing system.  It's job is to monitor the status of your emergency lighting system, run scheduled tests on the luminaires in your emergency lighting network, and combine and present the data in an easy to understand formats. 

The only control Lux Intelligent has over the emergency lights is the ability to simluate an emergency situation, which should trigger the light to drop into it's emergency state.  It is the emergency lights response to this simulation which is tested, i.e. is it able to provide sufficient light whilst operating on the emergency supply (self contained or central battery), and once back on mains supply does the battery recharge.

How many emergency lights do I need?

There is no specific quantity of emergency lights specified.  The requirement is that you provide sufficient lighting levels, in the event of a mains failure, for people to safely exit from a building. 

Using the relevant standards BS EN 1836/BS 5266-7, the light level requirements for the building can be determined.  From that, the type and quantity of luminaires can be determined.


Does Lux Intelligent only work with self-contained systems?

Lux Intelligent can work equally a well with fully self-contained emergency lighting systems as well installations that use central battery or static inverters to provide their emergency cover. 

The flexibility of the system ensures all the necessary operating characteristics of a self-contained luminaire can be monitored and reported, whilst also allowing luminaires to be simply monitored for actual light output in the case of central battery or static inverter supplied units. 

As an added bonus, the control panel can interface to such systems and force them in to test as well as monitor for such units reporting faults.

What is Lux Intelligent?

Lux Intelligent is an automatic emergency lighting testing system, manufactured by Advanced Electronics, and has been in operation for over 15 years.

The Lux Intelligent panel constantly monitors the state of all the luminaires on the emergency lighting network, reports any current faults on the network, and automatically executes scheduled testing of the luminaires on the network.

The emergency lighting testing panel works in unison with a PLU unit which is fitted inside each luminaire.  The PLU contains the electronics used to simulate an emergency situation and put the luminaire into it's emergency state.  It will then monitor the battery and light level states and report that data back to the panel.

Lux Intelligent also includes desktop PC software for collating the Luminaire status and test history information into Panel Reports, providing a log of the test shedule and historic test results.

Additional to this Lux Intelligent also has a cloud monitoring service which allows a customer to amalgamate data from all the panels in their emergency lighting network, or from multiple emergency lighting networks into a cloud storage platform, and then access that data in real time via their mobile device or a dedicated web browser based interface.
