EMERGENCY LIGHTING

Emergency lighting is a vital and necessary safety requirement for most building types. The safety it provides for occupants is paramount and not negotiable.

Product Safety

  • All Havells-Sylvania carry the CE mark. They are designed to conform to BS EN 60.598 2-22 and are manufactured in accordance with the quality system BS EN ISO 9001:2000 under certificate number FM01687
  • Any emergency lighting luminaire conversion other than by Havells-Sylvania to a CE marked luminaire invalidates this CE marking and its associated legal protection

Emergency Lighting Equipment

This comprises an inverter plus a set of batteries, which conform to BS EN 60.598 2-22 and may be mounted:

  • Integral within the luminaire (self contained – integral)
  • Remote from, but within 1 metre of, the luminaire (self contained remote)

Non-maintained Operation

In this mode of operation the emergency lighting lamps are not normally energized. An automatic monitoring and switching system is provided to switch on the emergency lighting if the normal supply is interrupted

Maintained Operation

  • A single lamp is used for both general and emergency modes
  • In multi-lamp luminaires only one lamp will be used for the provision of emergency illumination
  • Emergency lighting is provided for at least 3 hours (1 hour duration available to special order)

Maintained Remote Emergency Control

The majority of Havells-Sylvania maintained emergency luminaires are supplied with integral emergency control gear. Where the housing design precludes integral gear a remote control box is provided complete with connection cables.

Product Combined Operation (also known as Sustained)

  • Separate lamps provide general and emergency illumination
  • Emergency lighting is provided for at least 3 hours. (1 hour duration available to special order)

Self-testing

Automatic self-testing and monitoring of Havells-Sylvania luminaires is available to special order on a project basis

Central Battery

Havells-Sylvania luminaires for use with a central battery system are available to special order on a project basis

Legislation Changes & Requirements

The British Standard BS5266 has been revised to conform with the European Standard EN1838 (issued in the UK under reference BS EN1838/BS5266 Part 7) which specifies luminous requirements for emergency systems installed in premises. It also now calls up the luminaire product standard BS EN60598-2-22: 1999 Emergency lighting is provided for use when the supply to the normal lighting fails and is therefore powered from a source independent of that supplying the normal lighting. For the purposes of this standard emergency lighting is regarded as a generic term of which there are a number of forms.

Definitions

Emergency Exit
A way out that is intended to be used in an emergency.

Escape Route
A route designated for escape in the event of an emergency.

Emergency Escape Lighting
That part of emergency lighting that provides illumination for the safety of people leaving a location or attempting to terminate a potentially dangerous process before doing so.

Escape Route Lighting
That part of emergency escape lighting provided to ensure that the means of escape can be effectively identified and safely used when the location is occupied

Open Area Lighting
In some countries this is known as anti-panic lighting. This relates to that part of emergency escape lighting provided to avoid panic and provide illumination, allowing people to reach a place where an escape route can be identified

High Risk Task Area Lighting
That part of emergency escape lighting that provides illumination for the safety of people involved in a potentially dangerous process or situation and to enable proper shut down procedures for the safety of the operator and other occupants of the premises

Areas Covered/Levels of Illumination

Defined Escape Route
Based on 2m wide on the horizontal plane, preferably 1 lux but not less than 0.2 lux on the centre line. The lighting provided should operate within 5 seconds of the failure of the normal supply

Open Area (Sometimes referred to as ‘anti-panic’ lighting)
Not less than 0.5 lux at floor level of the open space. The ratio of max to min illuminance should be greater than 40:1.
