Parts of an emergency light

When analyzing the choice of an emergency lighting system, the following considerations should be taken into account: – Installation and Maintenance Costs -Lighting Quality -Lighting Availability.

First of all we must calculate the amount of Emergency Lighting Equipment needed to cover the area to be illuminated. This depends on the total luminosity of the equipment (at the end of the autonomy) and the distribution of the light provided by each one of them according to their characteristics (lenses, directional headlights, angular aperture, orientability, etc.).

The equipment without directional aiming must have an angular aperture of 120º, in order to achieve a wide lateral and vertical coverage. In this way we will have to place fewer fixtures and we will be able to homogenize the level of illumination at floor level.

Usually we must illuminate the emergency exit path and therefore the equipment must have accessories that incline it and thus illuminate the floor as the main objective. In these conditions we will achieve a higher level of illumination on the floor and / or workplace.

At what height should the emergency light be placed

This situation has led many opportunistic firms to try their luck in this field, taking advantage of the growing demand but ignoring the required safety standards. When we say that it is important to demand safety, we are saying that the emergency light must respond to what we expect from it and not represent a risk factor in itself. That is:

There are currently a large number of imported luminaires on the market that do not comply with the standard even though their advertisements say otherwise. Therefore, to make sure that a product really complies with the standard, there are a number of simple tests that can be done at home. It is worth spending just a few minutes to make sure that an element that should provide safety is really safe.

As far as insulation materials are concerned, the standard requires a glow tip test at 850°C on the plastic parts that provide insulation of the parts under voltage greater than 50 volts. This is something difficult to check in our homes, but there is a test that gives us an approximate idea of compliance with this point.

Distances between emergency lights

In this case, the REBT recommends the use of emergency luminaires with the AUTOTEST system, which informs in real time about the status of the luminaires. Specifically, Emergency Luminaires with AUTOTEST are defined as those that automatically perform all the tests indicated in the UNE-EN 50172 standard, which is a simple way to reduce the cost and facilitate the revision and maintenance of the installation. Any person can supervise the Emergency Lighting system in a simple way. In addition, thanks to the rigor with which the operation of the luminaires is known, this system provides greater security for the premises.

In the event of failure to properly maintain the emergency luminaires, the owner is responsible for any problems that may arise. A failure in the emergency lighting is a problem for the occupants to reach a safe place or locate any of the safety elements such as push buttons, fire extinguishers or BIEs (Equipped Fire Hydrants).

How often emergency lights are installed

It has already been published in the Bulletin of the Community of Madrid the decree that requires the installation of emergency lighting autotest in all equipment that are installed from 3 months (July).

“The emergency lighting devices installed after the entry into force of this decree must have an automatic system to test the correct operation and assigned autonomy. The owner of the equipment will be responsible for having the documentation that proves the date of installation of the same.    In addition, emergency lighting devices may only be used if they have automatic systems for testing correct operation and autonomy (self-test system) that warn the user if the equipment stops working. In addition to this, there is the obligation to use non-fire propagating conductors with reduced smoke emission and opacity in the interior installations of non-industrial buildings”.

They are autonomous emergency blocks that self-diagnose themselves in search of possible anomalies that could compromise their operation. They do this in real time and also perform periodic tests in accordance with current standards (EN 50172):
