Question 1: What is an Emergency Lighting Luminary? How can it be connected to the mains?

Emergency Lighting Luminaries are luminaries that continue to illuminate in the case of a power outage through the Emergency Lighting Unit it has, in addition to their regular functions. During its connection to the mains, in addition to the “Switched Phase” and “Neutral”, there has to be a “Un-switched Line” in order to feed the Emergency Lighting Unit. This line must not be cut under any circumstances except for a breakdown or for testing purposes. When Emergency Lighting Luminaries need to be tested, in order for them not to affect other luminaries, the feeder line should be separated by a different fuse on the board.

Question 2: When I turn off the switch connected to the Emergency Lighting Luminary, one or two lamps continue to illuminate. What is the reason for that?

It is possible that you have switched the phase end of the Emergency Lighting Unit (EML.U) that is located in your Emergency Lighting Luminary. This end has to be fed from the un-switched line. When you cut the power going to this end, the Emergency Lighting Unit continues to ignite the lamp believing that there is a power outage. It has to be checked that the Electronic Ballast is fed from the switched line and the Emergency Lighting Unit circuit is fed from the direct line.

Question 3: Can I feed the “Switched Line” and “Un-switched Line” ends on my Emergency Lighting Luminary from different phases? Could this type of an application harm the circuit or the fluorescent lamps?

Since Beş A Emergency Lighting Units are designed to have two relays, the circuit and the fluorescents are not harmed by this type of use. But this type of use might have a drawback. In the case that one of the phases, in particular the phase that feeds the Electronic Ballast, is cut and that the phase of the Emergency Lighting Unit continues to work, the lamps will be turned off because the power does not reach the Electronic Ballast and since there is power in the Emergency Lighting Unit it will not work in the emergency mode. Therefore, the Emergency Lighting Luminary will not fulfill its duty. Considering the probability that such a situation may occur, we recommend that the Ballast and the Unit inside the Luminary should be fed from the same phase.

Question 4: When there is power in the Emergency Lighting Luminary the lamps do not illuminate. When I cut the power one of the lamps switch to the emergency mode and start illuminating. What may be the reason for that?

If the lamps do not illuminate when there is power and they start illuminating when the power is cut, this means that the Emergency Lighting Unit inside the Luminary is working. In such a case it has to be checked whether the power reaches the electronic Ballast inside the Luminary or not, and whether the Ballast or one of the lamps is damaged or not. If the power reaches the Ballast, and the Ballast and the lamps are working, the wiring diagram and particularly whether there is a loose connection in the cable lead-ins in the sockets or not, has to be checked carefully. The Emergency Lighting Unit can ignite the connected lamp only when the two opposite ends touch each other, whereas in the Electronic Ballasts if any end is not touching no lamps can be ignited.

Question 5: When there is power in the Emergency Lighting Luminary the lamps illuminate. When I cut the power none of the lamps switch to the emergency mode. What may be the reason for that?

If all the lamps illuminate when there is power and none of them illuminates when the power is cut, the battery connected to the Emergency Lighting Unit should be controlled. First of all, it has to be checked whether there is a loose connection or not in the socket that connects the battery to the Emergency Lighting Unit. Then, after being sure that there is no power cut, the battery should be charged for at least 24 hours. If the same situation occurs again during the control after charging, the battery should be charged for the second time in a different working luminary to determine whether the source of the problem is the battery or the Emergency Lighting Unit. A negative outcome from this last test means that the life of the battery has ended, whereas a positive outcome means that the problem is in the charging circuit of the Emergency Lighting Unit.

Question 6: No lamps illuminate both when there is power in the Emergency Lighting Luminary and when the power is cut. What may be the reason for that?

In such a case, it has to be made sure that the power reaches both the Emergency Lighting Unit and the Electronic Ballast located in the luminary. It is normal that the lamps do not illuminate if the power reaches only the ballast and not to the Emergency Lighting Unit. In order for the lamps to illuminate when there is power, there must be power both in the Emergency Lighting Unit and the ballast. Whether the power reaches the Emergency Lighting Unit or not can be checked through the charging LED on it.

Question 7:  When there is power in the Emergency Lighting Luminary the lamps illuminate. When I cut the power one lamp illuminates in the emergency mode, but I want two lamps to illuminate in the emergency mode. Is it possible?

It is not possible with your current Emergency Lighting Unit. For such an application, there are Emergency Lighting Unit solutions that ignite two lamps up to 18W in the emergency mode. You can use two Emergency Lighting Units for larger capacities.

Question 8:  When there is power in the Emergency Lighting Luminary the lamps illuminate. When I cut the power one lamp illuminates in the emergency mode, but it stops illuminating soon. What can be the problem?

First of all, it has to be checked whether there is a loose connection or not in the socket that connects the battery to the Emergency Lighting Unit. Then, after being sure that there is no power cut, the battery should be charged for at least 24 hours. If the same situation occurs again during the control after charging, the battery should be charged for the second time in a different working luminary to determine whether the source of the problem is the battery or the Emergency Lighting Unit. A negative outcome from this last test means that the life of the battery has ended, whereas a positive outcome means that the problem is in the charging circuit of the Emergency Lighting Unit.

Question 9: The Emergency Lighting Luminary works normally, but it illuminates very weakly in the emergency mode. Is this normal?

According to the Emergency Lighting Standards, the level of the light in an emergency must be higher than 10% of the normal level. If you believe that your emergency lighting level is lower than this ratio, please check the wiring diagram, the battery value that is recommended for the Emergency Lighting Unit you use and the lamp/s in that order.
