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.

Question 1: I have a product called Emergency Lighting Unit (EML.U). I want to use this product in a Luminary with an Electronic Ballast of 4x18W capacity. How am I going to connect it?

The connection of the Emergency Lighting Unit with an Electronic Ballast changes according to the brand and the model of the ballast used. Therefore, specifying only the power value is not enough. The wiring diagrams can be found on the Beş A website. For your requests for diagrams that cannot be found on our website, please send the fluorescent connection sketch on the ballast that you use to the email address info@bes-a.com and we are going to draw and send you the wiring diagram you need.   

Question 2: I have a product called Emergency Lighting Unit (EML.U). Can I use this product in a Luminary with a Mechanical Ballast of 4x18W capacity?

The connection of the Emergency Lighting Unit with a Mechanical Ballast does not change according to the brand and the model of the ballast used. You can find the wiring diagrams on the website http://www.bes-a.com.tr/en/dokumanlar/acil-aydinlatma-kiti-baglanti-semalari/mekanik

Question 3: I have a product called Emergency Lighting Unit (EML.U). I want to use this product with Fluorescent Lamps with 2 pins. How am I going to connect it?

Emergency Lighting Units (EML.U) can only be used with Fluorescent Lamps with 4 pins.

Question 4: I have a product called Emergency Lighting Unit (EML.U). Can I use this product with an energy saving lamp?

An Emergency Lighting Unit (EML.U) can only be used with Fluorescent Lamps with 4 pins. From the operational point of view, it has the function of switching between the Electronic Ballast and the lamp with 4 pins. When there is power it connects the ballast to the lamp and when the power is cut it disconnects the lamp from the ballast and it ignites the lamp. In energy saving lamps the ballast and the lamp is integrated. Since it is not possible to intervene in energy savings lamps at all, they cannot be used with these products.   

Question 5: How long is the charging time of the batteries of Emergency Lighting Units?

For 1-hour-capacity products at least 48 hours of charging time is needed for the first use. For the next charges 24 hours are enough. For 3-hour-capacity products at least 96 hours of charging time is needed for the first use. For the next charges 48 hours are enough.

Question 6: What does Continuous, Emergency and Integrated mean in Emergency Lighting Units?

Emergency Model: It ignites the connected fluorescent only in the case of an emergency. Continuous Model: It ignites the connected fluorescent continuously when an external ballast is used. Integrated Model: It ignites the connected fluorescent continuously through the ballast integrated in it.

Question 7: Should I use batteries of what value and capacity in Emergency Lighting Units?

In Emergency Lighting Units batteries of different values and capacities are used according to the type and value of the lamp that is being used and its emergency lighting time. This value is written on the product label that can be found on each Emergency Lighting Unit. In order not to face any kind of problems, please use a battery with the value and capacity that is written on the Emergency Lighting Unit.

Question 8: How can I figure out how much is the lighting time of an Emergency Lighting Unit in an emergency?

On Emergency Lighting Units there are product codes that start with “EMLU……” and end with “…/1H” or “…/3H”. “1H” at the end of the product codes means that the product has 1 hour capacity, whereas “3H” means that the product has 3 hours capacity in an emergency.

Question 9: I have an Emergency Lighting Unit with the product code “EMLUS-T8/15-58/1H”. Can I use this product with my luminary of 2x28W capacity?         

Emergency Lighting Units are produced with different product codes according to the types and values of Fluorescent Lamps. The lamp values that each product can use are written on the product labels. In order not to face any kind of problems, please do not use the product with fluorescents other than those, the types and values of which are written on the product label.

Question 1: What do the single side or double side options given for exit luminaries mean? What is the factor determining this?

These options are about the visibility of the symbols used in exit luminaries from single or double side. This option changes according to the intended use of the exit luminary. For instance if luminaries will be used in accordance with fire regulations, they can be used single sided or double sided at places like corridors and above the doors.

Question 2: How and for what purpose is the emergency test button used?

This is a button that is used for simulating a power outage. When this button is pressed, the power reaching the emergency lighting unit is cut and the functioning of the product in an emergency is tested.

Question 3: What do the terms AC and DC mean?

AC is the short form for Alternating Current and DC is the short form for Direct Current. AC indicates the alternating and sinusoidal voltage of 220V that is present in the mains, whereas DC indicates constant voltage. DC voltage can be obtained by rectifying AC voltage.

Question 4: What kind of options do you have for the symbols and language that you use on your exit luminaries?

We do not have a limitation on the choice of symbols and language. Our range of symbol and language options is unlimited. We accommodate all the requests and demands coming from our customers.

Question 1: What are the differences between analog ballasts with filter and digital ballasts with filter?

Digital ballasts get less hot compared to analog ballasts and their designs include MOSFETs, whereas analog ballasts contain transistors. Moreover, digital ballasts have a safety feature for the protection of fluorescent lamps.

Question 2: What are the differences between electronic ballasts with filter and electronic ballasts without filter?

Electronic ballasts with filter can prevent and filter the total harmonic distortion (THD) in the current coming from the mains, whereas electronic ballasts without filter are not capable of doing that.

Question 3: What is warm-start and cold-start? Which of these techniques do you use in your products?

In warm-start, the cathodes of the lamp are preheated to the right temperature and the ignition of the lamp is optimized. This prolongs the life of the lamp. In cold-start the cathodes of the lamp are ignited without preheating and this causes faster consumption of the emission materials of the cathodes. We use warm-start in our products.

Question 4: What does power factor and ballast luminance factor in electronic ballasts mean?

Power factor is the factor that defines the proximity of the total power extracted from the mains to the active power. If the power factor is close to or equal to 1, it is a good sign. If that is the case, the power extracted from the mains decreases. In electronic ballasts this value is approximately 0.95 and the power factors are good. Ballast luminance factor is the ratio of the light intensity emitted by a lamp working with a specifically produced ballast to the light intensity emitted when working with the reference ballast.

Question 5: What does active and passive PFC (Power Factor Correction) mean?

In active PFC the power factor approaches 1. In passive PFC the power factor is corrected at a specific ratio and limited value.

Question 1: What does IP (Ingress Protection) Class mean?

IP Class is a standard that was developed for rating the environmental protection provided by an electrical protection. IP Classification generally consists of 2 (or 3) numbers.

1)       Protection from solid objects and materials

2)       Protection from liquids

3)       Protection from mechanical impacts

For instance for a product at the protection level IP 23C, number 2 indicates the protection level from solid objects and number 3 indicates the protection level from liquids. Letter C indicates the protection type from mechanical impacts.

Question 2: Can the use of sensors in luminaries with LED and fluorescent lamps cause problems?

The use of sensors in luminaries with LED does not have any kind of a negative impact. However, the use of sensors in luminaries with fluorescent lamps is not suggested. Since the sensor would turn on and off the fluorescent lamp very frequently, this would shorten the life of the lamp.

Question 3: What is the difference between fluorescent lamps and LEDs in terms of energy efficiency and energy savings?

LEDs are on average 40%-50% more energy efficient compared to fluorescent lamps and they have a longer life as well.

Question 4: What are the conditions for using luminaries with LED efficiently?

LEDs should be used at the temperature and environmental conditions that are indicated on the product catalogue. Moreover, attention must be paid not to exceed operating current values.

Question 1: I have an Emergency Lighting Unit with the product code “EMLUS-LED/41-60/1H”. I made the connection according to the diagram on the unit, but my luminary does not work when there is power and it illuminates in the emergency mode when I cut the power.

As it is well known LEDs have positive (+) and negative (-) poles. First of all the LED and LED driver outlets should be correctly connected to the Emergency Lighting Unit in order for your product to work correctly. If your product works in an emergency but it does not work when there is power and if you see the mains voltage of 220V in LED driver inlets, then a possible reason may be that LED driver outlets are connected inversely to the Emergency Lighting Unit. This is a common cause of this kind of problems.

Question 2: I have an Emergency Lighting Unit with the product code “EMLUS-LED/41-60/1H”. I made the connection according to the diagram on the unit, but my luminary works when there is power and it does not illuminate in the emergency mode when I cut the power.

As it is well known LEDs have positive (+) and negative (-) poles. First of all the LED and LED driver outlets should be correctly connected to the Emergency Lighting Unit in order for your product to work correctly. If your product works when there is power but it does not work in an emergency, firstly it needs to be checked whether the battery is connected, whether there is a loose connection in its socket and whether it was charged adequately or not. If possible, the battery voltage should be measured and it needs to be checked whether this value is equal to or greater than the value written on it. If it is clear that there is not a problem with the battery, then the possibility that both the LED and LED Driver outlets could have been connected inversely to the Emergency Lighting Unit should be looked at, since with such a connection the product works when there is power and it does not work in an emergency.

Question 3: Is there any kind of a safety feature in EMLUS-LED model Emergency Lighting Unit – LED products?    

EMLUS-LED model Emergency Lighting Unit – LED products have short circuit and open circuit safety features. When the product is working in the emergency mode during installation or during actual usage, in the case that LED ends are short circuited or left out of the circuit the product starts to protect itself. After LED connection is corrected in order for the product to work again in the emergency mode, the power reaching the product should be turned on and off.

Question 4: What is the difference between EMLUS-LED and EMLUS-XLED model Emergency Lighting Unit – LED products?

EMLUS-LED and EMLUS-XLED model Emergency Lighting Unit – LED products have absolutely the same features in terms of working logics and application. EMLUS-LED drives the LEDs in the emergency mode with an average current of max 75mA, whereas EMLUS-XLED can drive the LEDS in the emergency mode with 150mA with the EMLUS-XLED150 model and with 300mA with the EMLUS-XLED300 model.

Question 5: Can I ignite the LED Fluorescent Products that work directly under 220V with the models EMLUS-LED and EMLUS-XLED?

EMLUS-LED and EMLUS-XLED model Emergency Lighting Unit products are LED Driver circuits that work with a battery in the emergency mode. They can directly feed the LEDs under certain constant current values. Therefore, they can be used only in the luminaries that have independent drivers.

Question 6: Do you have an Emergency Lighting Unit product with which I can ignite the LED Fluorescent products that work directly under 220V?

We have emergency lighting unit solutions with which you can ignite LED products that work directly under 220V. You can use EMLUS-LED220 for your 3W-5W spot products and you can use EMLUS-220 for your LED fluorescent, downlight and panel luminaries with a power of 10W-30W.

Question 7: How bright do EMLUS-220 model 220V Emergency Lighting Unit – LED products ignite the luminaries in the emergency mode?

EMLUS-220 model 220V Emergency Lighting Unit – LED products ignite the luminaries at the same brightness level under regular power, meaning at 100% brightness level.

Question 8: Do you have products that can ignite the LED Fluorescent products that work directly under 220V at a lower brightness level in the emergency mode?

We have an emergency lighting unit solution with the model EMLUS-220S that satisfies this demand. Nevertheless, since this solution could be applied depending on the specifications of the luminary and on whether the luminary is compatible or not and since it is specifically designed for the luminary in question, it cannot be advertised. You can send us your sample luminary for your custom demands.

Question 1: Do your LED Drivers supply constant current or constant voltage?

Our LED Driver solutions with model numbers LDRV-10 and LDRV-50 work with constant current.

Question 2: What is a constant current LED Driver?

Constant current LED drivers always supply the current indicated on them to the LEDs constantly without any alteration within the operating voltage range.

Question 3: Do your LED Driver solutions have isolation? Do they contain a PFC circuit?

We have LED Driver solutions with model numbers LDRV-10 and LDRV-50. Both of these solutions have circuits with isolation. Moreover, both solutions have a PFC circuit.

Question 4: What kind of safety features do your LED Driver solutions have?

Our LED Driver solutions have safety features for short circuit, open circuit and excessive load. If the outlets of LED Driver are short circuited when the LED Driver is active, the safety circuit is activated. So in order for the LEDs to illuminate again after the short circuit is fixed, it may be necessary to cut the power at the inlet of the LED Driver and to supply power again.
