During the advice visits to our clients facilities, lots of times it is observed that emergency lighting is not checked or maintained, so in an emergency event can´t make its main function, which is provide light along escape routes, protection systems and safety equipment, signs and indications,…
In an user level, as a preventive measure, we can regularly test how it works, switch off the circuit switch named “emergency” in the electric panel.
If lighting doesn´t works, most frequent failure are:
- Fluorescent tube or lamp (indeed, there are emergency lighting still with lamps) burnt-out;
- Fluorescent tube or lamp turned on, without a cut in the electrical current;
- Battery fail (when the electrical current cuts, the light turns on but lasts a few seconds);
- Burnt-out indicators (some emergency lighting have indicators for AC and battery charge).
Lack of information makes that workers themselves try to repair an emergency light: the most probable is that the model is already unlisted (and it is not even manufactured), as a consequence, it is difficult to find spare parts for models “relatively old” (i.e. lamps and batts).
My recommendation is always to call an electrician or maintenance staff (I always do because I´m not a handy man) since lots of times it is not enough with replacing a light´s batt, but the problem can´t be detected (i.e. resistance fails, transistor,…).
If a replacement is required, there are already available LED emergency lighting for less than 30€, improving the features of previous emergency lighting:
- More energetic efficiency;
- More than 9-10 hrs. of autonomy;
- 50.000-60.000 hrs. life;
- 300 lumen (lux = lumen/m2) intensity;
- Individual LEDs, replaceable in some models.
Do you have to replace an emergency light?. Will you repair or replace it for one with LEDs?.
