Need for Emergency Lighting

Emergency lighting is a lighting system designed to illuminate designated escape routes for emergency situations in a development when the main power supply fails. The emergency lighting system shall supply adequate lighting levels along escape routes, clearly illuminating directional displays to the nearest designated exit, and illuminating all life safety systems such as fire extinguishers etc.

The IS:3217:2013:NSAI Standard determines the minimum statutory guidelines to which all emergency lighting installations must adhere to. This standard is embedded in the 2003 Fire Act

Regulatory Requirements

IS:3217:2013:NSAI requires that;

Minimum Lighting Levels:

  • Minimum light level of 1 Lux on all defined escape routes (e.g. Centre line of Corridor).
  • Minimum light level of 0.5 Lux on all undefined escape routes (e.g. Open plan area).
  • A minimum illuminance level of 5 Lux to the vertical (face of equipment/device) on all fire-fighting equipment, Manual Call Points, Fire Alarm Panels, First Aid Posts and Electrical Distribution Panels. In practice, in order to obtain the required lighting level an emergency fitting is required above locations.
  • In areas of high risk the maintained illuminance on the task area plane shall not be less than 15 Lux

Points of emphasis when locating Emergency Fittings:

  1. Exit sign above all exit doors
  2. Near stairs so that each flight of stairs receives direct light. (Near is deemed to be within 2 meters)
  3. Near any change of level,
  4. Any change of direction,
  5. At each intersection of corridors,
  6. Near each final exit and outside the building to a place of safety.
  7. A bulkhead near all exit signs
  8. Near escape equipment provided for the disabled, disabled refuges, disabled refuge panels and call points.

Types of Emergency Lighting

Most emergency light fittings fall into one of the following categories:

  • Non-maintained – The emergency light units only illuminate in the event of a mains failure.
  • Maintained – The emergency light units are illuminated at all material times using the same lamps for both normal and emergency operation.
  • Sustained – The emergency light units are fitted with two lamps or two sets of lamps. One of which operates on mains 240V AC supply, the other which operates from the battery supply in the event of mains failure.

Regulatory Requirements

Emergency Lighting systems are required by law (statutory requirement) to have a preventive maintenance contract in place. It is the responsibility of the owner/occupier/management of the building to ensure that the emergency lighting system is maintained in accordance with the standards. The current Irish Emergency Lighting standard (IS:3217:2013:NSAI) requires that a simulated mains power failure be carried out on the building, four times a year, every three months. The four visits shall incorporate

  • 3 quarterly visits, with a mains power failure simulated for 30 minutes
  • 1 annual visit, with a mains power failure simulated for three hour

An engineer will walk the development and visually determine that all emergency luminaires and lamps are operational and illuminating for the duration of the test.

Following the termination of all simulated power failure tests, check that all emergency luminaires are still operational and illuminating correctly, and that the green LED status indicators are showing a healthy condition.

Periodic Testing

Lara-Alarms-Dublin-FLUKE-1650-SERIESNo electrical installation, no matter how carefully designed and erected can be expected to last forever. Deterioration will take place due to age as well as due to normal wear and tear. With this in mind the Wiring rules recommend that the installation should be inspected and tested periodically to ensure that the installation still complies with the rules.

The time interval between inspections will depend on the type of installation and the way in which it is used. Table 1 shows suggested intervals between periodic inspections, as specified by ETCI.

Type of InstallationMax Period Between Installations
Domestic Premises5 – 10 Years
Commercial Premises5 Years
Educational Establishments5 Years
Hospitals5 Years
Industrial Premises3 Years
Places of Public Entertainment1 Year
Agriculture and Horticulture3 Years
Emergency Lighting3 Years
Fire Alarm Systems1 Year
Temporary Installations3 Months

Certification & Reporting

The National Wiring Rules requires the recording of inspection and testing which has been carried out in accordance with the standards. The information to be recorded includes a description of the installation, circuit details including type and ratings of protective devices and test results.

Maintaining accurate Test Record Sheets as evidence of inspection and testing records of a new installation or an extension is an essential and most important component of any electrical contract whether minor or major.

To neglect to hold such records is a serious breach of the wiring rules and in addition would leave the electrical contractor open to being held responsible for work or additions done by others subsequent to the verification of his contracted work.
