Why Emergency Lighting

• In case of event which make a power cut,
  Emergency Lighting must provide enough light in
  order to

Guarantee clear marking of emergency
exits Facilitate the safe evacuation of
people Help to localise fire alarm and first aid
devices
Guarantee a minimum light level to avoid panic by
occupants and enable activities to continue

Synthesis of EN standard

• Market hold by EN regulation and possible local
  deviation
• Chance to pull up market (technology / price)
  connected to safety market
• Schneider Electric is fully aligned with this
  approach.

Types of applications

• 3 sub-categories for Safety Lighting

7
Escape route

• Standard EN 1838 says
• If Escape routes wider up to 2 m, luminaries must
  be installed to ensure a minimum level of
  lighting (1 lux) on the floor along the central
  line of the escape route.

8
Anti-panic area

• Standard EN 1838 says
• For anti-panic area, luminaries must be installed
  to ensure a minimum level of lighting on the
  floor until 0.5 m from the wall.

Midday on a sunny day 50,000 to 100,000 lux
A sunny afternoon 35,000 lux
Overcast sky 32,000 lux

Location of the luminaires
19
Location of the luminaires

• At each Door

20
Location of the luminaires

• Signs are required whenever the direction of
  escape is ambiguous

21
Location of the luminaires

• Near changes of direction

22
Location of the luminaires

• Near each flight of stairs

23
Location of the luminaires

• At each change of floor level

24
Location of the luminaires

• Near each intersection

25
Location of the luminaires

• Near each Fire Alarm call point - fire fighting
  equipment

26
Location of the luminaires

• Near first aid posts

• But
• First Aide Site, Fire fighting equipment and call
  points should be more lighted than escape route,
  when not located on an escape route not located
  on an escape route or in an anti-panic area.

27
Location of the luminaires

• Over High Danger Areas

28
Location of the luminaires

• Over Technical Areas

29
Location of the luminaires

• Outside each final exit

Anti-panic Escape Route


32
What type of product to be used depending on the
need

• Anti-panic area
• Luminance to provide the right luminous flux at
  the ground level

• Criteria
• Height of the ceiling (impact on the needful
  flux).
• Surface of the area (impact on nb of luminaires
  to be installed).

33
What type of product to be used depending on the
need

• Escape Route
• Luminance to provide the right luminous flux at
  the ground level
• Visibility distance to indicate efficiently the
  route of escape

• Criteria
• Height of the ceiling (Flux of the product).
• Dimension of the screen (impact on nb of
  luminaires to be installed).

34
Distance between E.Lighting blocks

• Influent parameters
• Safety Lighting
• It depends of the luminaire (shape, composition,
  flux)
• Location of the product
• Height over the floor, the mounting wall,
  ceiling, axes positioning
• The level of light required
• 1 lux, 0.5 lux, 15 lux

35
Distance between E.Lighting blocks

• Spacing Tables
• For each products exits a table which defines
  whether fittings are needed in addition to those
  required for the points of emphasis.

Maintenance rules EN 50172

• EN 50172 Periodic Maintenance test records
• Series of procedures to keep the safety lighting
  system working efficiently

• Daily
• Make a daily check of the energy source power
  supply indicators.

• System failures Should have be recorded on a
  register

• Annually
• Make a duration test on each lighting and sign
  luminairessimulating loss in standard power
  supply for sufficient time.

• Monthly
• Make a test of the luminaires, simulating
  failure of the standard power supply for enough
  time to allow verification of the start-up of the
  lighting devices and signs.
