FAQ Luznor

Minimalist emergency luminaire, energy efficiency and avant-garde design

Luznor Desarrollos Electrónicos S.L. is an advanced manufacturing company from Vitoria created in 1998 by a group of professionals with wide experience in the field of Emergency Lighting.  

The company started its activity with its main product line, emergency lighting, and soon after it also developed its other two specialties: programmable torches for professional use and continuous power supply equipment. 

All Luznor products are developed entirely in its only production plant, located since 2004 in its own 2,700 m2 industrial pavilion in Júndiz (Vitoria-Gasteiz).

Therefore, Luznor covers all phases of the industrial design process, from the definition of specifications ot the manufacture and marketing of the product, including both electronic and mechanical design and the relevant tests and approvals.  

In addition, in the specialty of the professional torches, Luznor completes its product portfolio by marketing other products, such as small format torches and portable lighting with different physical and functional characteristics to those it manufactures and suitable for both general use and ATEX (explosive atmospheres).

Any product can be purchased by making a request to Luznor. The Luznor sales department will manage this request either directly from the factory or by sending it to the corresponding delegation. 

Luznor has twenty national and seven international delegations. Luznor's sales staff or the corresponding representative will inform the customer, in turn, about the places where the product can be purchased depending on the area. 

Luznor's online shop is only available for national users.

All spare parts can be ordered directly from Luznor. The instruction manuals of all professional torch series include the list of spare parts. Only original spare parts or spare parts approved by Luznor are permitted. 

In the case of products with ATEX certification (explosive atmospheres), maintenance, spare parts or any other manipulation that implies a modification with respect to the original assembly is limited to qualified persons. 

Each Luznor product includes, inside the individual packaging, a document with the most relevant technical information. Depending on the type of product, this document differs: for all emergency lighting, an instruction sheet is provided; for continuous power supply units, a user manual is enclosed; and finally, for professional standard-reference torches, an instruction manual is included.  

If a torch with a standard designation has a special function, a supplement is added to the manual, while if the torch has a special designation because it is a completely customised development, it is supplied with its own instruction sheet. 

On this website, in the section of each product, you can find a technical data sheet and additional documentation to the one described here. For any other technical information, please contact Luznor. 

The chargers are single-phase with a shielded mains isolation transformer and a semi-controlled diode and thyristor bridge. This technology ensures high reliability and long life. 

Yes, typical examples are mains supply voltages other than 230 Va.c., different output voltages or number of battery elements, optional measuring devices, etc.

Any special requirements can be submitted to Luznor, whose technical department will be pleased to provide the most suitable solution. 

No. The output voltage is the voltage of the battery, the voltage of which depends on its state of charge, temperature, etc. In case of discharge the final voltage will be of the order of 1.10 V/e for Ni-Cd and 1.75 V/e for sealed lead. In charge the voltage will be of the order of 1.50 V/e in Ni-Cd and 2.27 V/e in sealed lead. 

Yes, the charger will provide its full rated current and the remainder will be provided by the battery, which will of course discharge. The battery will recover its lost capacity when the peak current ceases. 

By default all local alarms trigger the remote alarm after timing. However, it is easy to select that some do not. This should be requested to Luznor for proper configuration or procedure.

Any default that is detected and signalled locally on the unit's synoptic is transmitted remotely after a 10 to 20 second time delay. 

For this transmission, there is a potential-free changeover contact of a relay, which is wired to the internal terminals of the equipment and is available to the user. 

Ni-Cd batteries are more wear resistant, reliable and durable than sealed lead-acid batteries, making them the first choice for equipment where high reliability and long life are required. 
They provide high peak currents. They withstand full discharge and maintenance under full discharge conditions for weeks at a time. They also withstand high temperature conditions better. Their end of life is usually gradual, with a progressive loss of capacity. 
Their main disadvantage is their higher price and that their use is restricted to capacities of the order of 24 Ah maximum. 
When a higher capacity is required, sealed lead-acid batteries are normally used. There are different qualities of this type of battery. Luznor uses batteries with a design life of 10 to 12 years, but these are only available from a minimum capacity of around 18 Ah. 
Sealed lead-acid batteries cannot be fully discharged and cannot be maintained in a discharged state. For this reason, the equipment that uses them has a contactor at the output that cuts off any discharge as soon as it detects that the battery is discharged. Their end of life is usually quite abrupt and often without warning. 

Basically, two types of batteries are used:
    • Nickel-cadmium, watertight, cylindrical, maintenance-free, which are assembled in blocks of up to 10 elements, called flasks. 
The typical voltage of an element is 1.2 V and its capacity is 1.5 Ah to 7 Ah. Higher voltages and capacities are achieved by mounting elements in series and/or in parallel. 
    • Lead-acid, watertight, maintenance-free. 
Typical single-element voltage is 2 V and they are usually assembled in blocks of 6 elements (12 V). Higher voltages and capacities are achieved by mounting 12 V blocks in series and/or in parallel. 

The CB equipment provides continuous current at its output, both when there is mains voltage and when there is no mains voltage. There is no discontinuity in this voltage at the moment of mains failure or return. 
The CBQ equipment provides alternating current at its output when there is mains voltage and direct current when there is no mains voltage. There is a small voltage cut in the transitions from AC to DC output and vice versa. This equipment is mainly designed for loads that support both AC and DC voltage, such as incandescent lamps.

When the autonomy of the torch decreases significantly from its nominal value, it is necessary to replace its battery. Luznor recommends the replacement of the battery 5 years after the purchase of the torch, in order to ensure its performance at the time of use.  

All products manufactured by Luznor meet the requirements of the European Parliament and Council Directives for compliance with the CE Marking Directive 93/68/EEC:

  • 2014/35/EU. Making available on the market of electrical equipment designed for use within certain voltage limits.
  • 2014/30/EU. Electromagnetic Compatibility.
  • 2011/65/EU. Restriction of the use of certain hazardous substances in electrical and electronic equipment.

They also cumply with other directives:

It is not possible to recharge an ATEX torch in an explosion hazardous area, as the charger is not ATEX certified. Recharging must be carried out in a non-hazardous area.  

By contacting us by telephone on +34 945 200 961, by sending an e-mail to luznor@luznor.com or by using the contact form on this website. 

All torches of the LRX and HRX series comply with the Directive 2014/34/EU of the European Parlament and of the Council on equipment and protective systems intended for use in potentially explosive atmospheres (ATEX).

Specifically, the LRX series torches are suitable for use in ATEX zones 0, 1 and 2 (gas) and zones 20, 21 and 22 (dust) and have been certified by the Laboratorio Oficial Madariaga (LOM) with the following marking code:

Ex II 1 GD 
Ex ia IIC T4 Ga
Ex ia IIIC T85°C Da
-40°C ≤ Ta ≤ +40°C
LOM 15ATEX2183
CE 0163

The HRX series torches are suitable for use in ATEX zones 1 and 2 (gas) and zones 21 and 22 (dust) and have been certified by the LOM with the following marking code:

Ex II 2 GD 
Ex ib e IIC T2..T4 Gb
Ex tb IIIC T85°C Db
-40°C ≤ Ta ≤ +60°C (T2: lamp. 10 W – T4: lamp. 3 and 5 W)
LOM 04ATEX2129
CE 0163

In the QR, LR, HR, LRX and HRX series a number of front and rear signalling colours can be combined in both continuous and flashing mode. The signal colours can be red, amber, blue, green or white. 

There are two particular cases, the QR-3 and LR-3 torches, in which the main light can be coloured in addition to white. In the case of an RGBW main light source, this means a very different colour light emission from the signalling light, which is much more intense and focussed.

In the HS and QS series, due to the geometry of the torch, the signalling can be on the front but not on the rear, with the same range of colours as mentioned above. Cones for traffic control and other signalling functions can be used for these torches. 

Luznor's products are subject to two types of environmental taxes as the company, according to Royal Decrees 110/2015 and 106/2008, is a member of the Sistemas Colectivos de Responsabilidad Ampliada del productor (SCRAP) Fundación Ecolum and Fundación Ecopilas.

In the Downloads section you have at your disposal the document that includes the fees corresponding to each product. Both the fees and Luznor's registration numbers in the different SCRAPs are detailed in the invoices issued to customers. 

Luznor has a clear customer focus and each torch or charger can be customized, either by screen printing the customer's logo, serial numbers for product control or any other text or illustration requested. 

This screen-printing consists of laser marking, the finish of which may vary depending on the colour of the housing of the torch.  

All the chargers of the C-64 series can be fitted with a part that allows the mechanical fastening of the torch to prevent any relative movement between the torch and the charger and thus ensure the charging of the torch at all time. 

In the case of the C-34 and C-73 chargers, the very design of the chargers already has a strong attachment to the torches, as they are intended for installation in vehicles and other means of transport.

Standard reference professional torches come with an instruction manual, in which all functions of the torch's push buttons are described. Visual diagrams can also be found in the catalogues of torches. 

If a torch with a standard designation has a special function, a supplement is added to the manual, in which the particularities of the torch in terms of function are indicated. Whereas, if the torch has a special designation because it is a customized development, it has its own instruction sheet. 

In case of loss of the documentation associated with your torch, do not hesitate in contacting Luznor to have it returned to you or to clarify any operational doubts. 

The access to the flashing modes on standard programmed torches is done by long pressing the left push button, starting with the torch switched off.  

Once the flashing modes have been accessed, the following cycle is repeated by short presses: S.O.S. signal, flashing, light burst, etc. To turn the torch off, a long press is required again (from any position in the cycle). 

If you have a torch with a special designation or a standard designation with special function, the flashing modes may be different from those described here. 

Access to the power modes on torches with standard programming is done by long pressing the left push button, starting with the torch switched on.  

Once the power modes have been accessed, the next cycle is repeated by short presses: low, nominal, high, etc. To turn the torch off, a long press is required again (from any position in the cycle). 

If you have a torch with a special designation or a standard designation with a special function, the power modes may be different from those described here. 

Your torch is switched off because the standard emergency function, based on an automatic switch-on for 3 minutes designed to help you locate the torch, has finished.  

If you do not want the torch to switch off after the 3 initial minutes, simply press the left button briefly and it will switch on permanently at nominal power.  

If you have a torch with a special designation or a standard designation with a special function, i.e. a customised development, please refer to the respective accompanying documents, as the automatic switch-on function may differ from the one described here. 

Your torch has entered emergency mode.  

All torches with standard reference (in catalogue) incorporate an automatic switch-on of the spotlight during 3 minutes (emergency function) as soon as the torch is removed from the charger or the power supply to the charger fails. Therefore, if the torch has not been removed from the charger and has switched on, it is indicating that the charger is no longer powered. 

Exceptionally, it may happen that the torch has lost contact with the charger due to various environmental factors such as vibrations, movement, etc. In this case, simply place the torch back on the charger and, to avoid any relative movement between them, there is an option of adding a mechanical fastening that allows the torch to be securely charged even if the charger is on a vertical wall or upside down bolted to the ceiling. 

The LED light on the top left of the torch, under the handle, is an indicator of the charge status of the torch, i.e. the current available battery capacity. 

It only lights up when the torch is either switched on or charging on the charger, and can have four levels:

  • Red: available capacity less than 20%.
  • Amber: available capacity between 20% and 60%.
  • Green: available capacity between 60% and 100%.
  • Flashing green: totally charged (100%).

Luznor chargers are specifically designed to be able to store torches for long periods of time, regardless of their charge, as they have a maintenance charging system that avoids discharging the batteries without harming them. 

Unfortunately, unlike the C-64 series, the chargers of the C-34 series are only designed for HS torches and are not compatible with QS torches. Therefore, it is necessary to purchase a C-73 series charger. 

It should be noted that if a QS torch is placed on a C-34 series charger, it will not charge (if it is fast charger it will charge, but the charging status will not be correctly indicated on the torch) but, above all, it will not damage the QS torch or any of its components. 

Yes, all chargers of the C-64 series are compatible with the QR torches, being able to adapt to the charging of Ni-Cd, Ni-MH and Li-Ion batteries in the most efficient way for each battery. 

Yes, thanks to use of a programmable microprocessor, Luznor offers the possibilty of customizing the operation of the torches. This opens up a world of options: number of flashing sequences (flashing, S.O.S. signal and light bursts as standard), number of light powers (low, nominal and high as standard), signalling colours (both front and rear), etc. It is also possible to define the push buttons and the types of presses with which to access the requested functions, as well as the order in which they should appear.  

Yes, it is possible. Luznor has developed a "LED spotlight set” that allows the simple replacement of the halogen spotlight that the HR series torches have, as long as they do not have a front signalling crown. 

In this way, the purchase of a new torch is avoided with the economic savings and the reduction of waste generation that this entitles, while the quantity and quality of the light available is considerably increased, without altering the rest of the features of the original torch. 

In both systems, the same tests are performed on the devices. They are as follows:

  • Functional test: the lamp, the battery and the electronics are checked, the duration is 6 minutes and the periodicity with which it is carried out is 3 months.
  • Autonomy test: the lamp, the battery, the electronics and the autonomy are checked, the duration is 1, 2 or 3 hours (according to the autonomy of the device) and the periodicity with which it is carried out is 12 months.

The difference is that in devices with Autotest, faults are displayed locally by flashing two LEDs in red and green. 

In devices with Centralized Test, in addition to indicating faults locally as with the Autotest function, they are displayed on screen in real time. Luznor's own software allows the status of all the installed devices to be monitored visually and intuitively, facilitating the preventive maintenance of the entire installation.  

In accordance with article 20 of the Low Voltage Electrotechnical Regulation and ITC, the owners of the installations must maintain them in good working order, using them in accordance with their characteristics and refraining from intervening in them to modify them. 

The use of emergency lighting devices with Autotest function makes it easier for the owner to control and verify the correct operation of his installations.  

It is worth considering the option of the Centralized Test Function, in which all the devices are managed from a single central station, communicating with it through a communications bus. Thus, the owner can program in Luznor's own software the periodic testing of lamp, battery, communications and electronics, visualizing the results in the plan of its facilities and keeping a record of the maintenance by generating reports. 

This depends on the type of staircase on which the beacon lights are to be fitted.  

If you have a hollow staircase with a thickness of 2 cm, they can be fitted using different systems depending on the series: for the Matiz series there is a spring kit; with thread and nut in the PCM series and, in case of the Élite series, screwed directly to the surface or to a universal box for false walls. 

If the staircase is solid, there are different fastening systems depending on the series: the beacon lights of the Élite series are screwed to an universal box, while for the Matiz series it is necessary to use a Luznor box, which is smaller than the universal box. The PCM series can be screwed and nutted to a metal sheet or surface that covers the recess of the universal box.  

All three Luznor beacon light series have aesthetic frames to cover round and square universal boxes. 

Beacon lighting shall be installed on each step or ramp with an inclination of more than 8% of the room, with a sufficient level of illumination to light up the tread.  

They shall be installed at a rate of one beacon light for each linear metre of the width of the staircase and may be self-contained or centralized and regardless of the colour of the light.  

It should be mentioned that beacon lighting is not emergency lighting as such and therefore beacon lights cannot be used to justify it. This means that the fact that there is beacon lighting on a staircase does not obviate the obligation to install emergency lighting to illuminate the staircase. 

All Luznor fluorescent products have their counterpart LED version for quick and easy replacement.  

In addition to achieving higher quality and more energy-efficient lighting, the sizes and anchorages match, so that the previous installation and even, in some cases, certain parts of old products could be used, thus reducing the generation of waste (mainly plastics and metals). 

The substantial difference between both functioning modes is whether the lamp is switched on or not, in mains power presence. Thus, in a: 

  • Non-maintained device: there is no possibility of switching on the lamp in the presence of mains power and, when mains power fails, the lamp is automatically switched on by the power supplied by the battery.  
  • Maintained device: the lamp can be switched on or not (choice of the user) in presence of mains power and, when this fails, it is switched on automatically by the power supplied by the battery. 

Yes. Luznor has maintained emergency lighting devices for this purpose. 

These models allow the user to switch the lamp on or off at will in the presence of mains power and also provide emergency lighting in the event of mains power failure.  

On the other hand, Luznor also has devices called luminaires, which act as general lighting without providing emergency lighting in the event of mains power failure, as they do not have a battery inside (with the consequent reduction in cost). 

With a combination of devices and luminaires, it is possible to cover both general and emergency lighting, while maintaining the same aesthetics throughout the space under consideration.   

The UNE-EN 60598-2-22 standard states that the luminaire must be operated in such a way that the battery fulfils the expected 4 years of its normal operating life. It also mentions that the battery or the entire luminaire should be replaced when it is detected that its autonomy has decreased significantly with respect to the theoretical autonomy. 

Taking into account the above paragraph and that, in addition, the ambient temperature depending on the application greatly affects the life and capacity of the batteries, generally, a suitable battery replacement period would be 4 years. Each Luznor device has in its instruction manual the steps to follow for battery replacement. 

The emergency lighting devices do not require any maintenance except for cleaning the outside of the device, so as not to hinder the emission of light when it is necessary. For this purpose, a damp cloth wrung out with a mild household detergent is recommended. 

Luznor has a flexible and accessible technical staff at its disposal at all times, capable of dealing with a complete development, from the specification sheet to the delivery of the product, including  the relevant electronic and mechanical development.  

The Technical Office and R&D&I staff have a great technical capacity and experience when it comes to undertaking customized developments, even if they involve the study of specific directives or standards, the performance of laboratory tests and the required homologation or certification. 

Luznor has many developments with autonomies and luminous fluxes (lumens) that do not appear in the catalogue.  

Even if they involve the assembly if new electronic cards or the incorporation of batteries of other technologies, do not hesitate to transmit your needs to Luznor's technical team, who will try to provide the optimum solution either by adapting existing products to the required parameters or by developing a new product. 

Primarily, you will need the floor plan of the enclosure to be studied in DXF format. As complementary information, it is advisable to have a plan of sections, conventional lighting, fire protection elements and evacuation routes.

If the green LED goes out when the device is powered by mains voltage, this indicates that the device is not charging the battery. The following two basic checks are recommended:

  • Check that the mains power supply is correct
  • Check that the battery is properly connected to the control board 

If after these checks the device still has the green LED turned off, it is very likely that there is a fault in the electronics of the device. Please contact Luznor to find the best solution to the problem.

Yes, if you need Luznor to carry out the lighting calculation, you can contact the sales department, who will not only provide you with the economic offer of the products resulting from the lighting study, but will also provide you with a complete report as a technical offer. 

The lighting calculation service and delivery of the report is free of charge. 

When an emergency lighting device is in the charging state, i.e. mains power is present, the green LED will be on, indicating that the device is charging the battery correctly. 

However, when the mains power fails, it is the device that provides emergency lighting by switching on the lamp using battery power. In this emergency mode, the green LED will be off, indicating that there is no mains power. 

All devices are accompanied by an instruction sheet detailing the installation and operation of the devices.

The data to be included in the calculation report are eligible by the user of the PCI software.

By accessing the “Datos a imprimir” section of the “Proyecto” submenu, you can decide whether to include one or all of the following aspects: Características del recinto (Enclosure characteristics) and resumen del cálculo (calculation summary), Vista en planta (Plan view), Posiciones de las luminarias (Luminaire positions), Iluminancias en recinto (Enclosure illuminances), Diagramas isolux (Isolux diagrams), Niveles de grises (Grey levels), Recorridos de evacuación (Evacuation paths) and Puntos de control (Control points).

A file with an LDT extension is a file type that stores the lighting parameters of a luminaire such as its size, the number of lamps in the luminaire, its luminous flux, etc.

This file allows lighting calculations to be made with Luznor luminaires using Dialux software. The LDT files of all Luznor emergency lighting devices are available on this website for free download and use.

Yes, the BC3 files for Luznor emergency lighting devices can be downloaded from this website as well as from the ACAE website.

The REBT establishes the technical conditions and guarantees to be met by low voltage electrical installations, i.e. with a voltage of less than 1,500 Vd.c or 1,000 Va.c.

It applies both to new installations and to installations existing before its entry into force that are subject to major modifications or when their state, situation or characteristics imply a serious risk to people or property. It is mandatory and is divided into a formal part (articles) and a technical part made up of 52 Complementary Technical Instructions (ITC).

Yes, you can download the Luznor catalogues in PRESTO and FIEBDC format from this website as well as from ACAE's website.

This information on the REBT and other applicable regulations is available in Luznor's Emergency Lighting Regulations and Application Guide. If you need additional information, please do not hesitate to contact Luznor.

The ITC-BT-28 defines when a premises is defined as a place of public concurrence. In summary, public premises can be grouped by type:

  • Entertainment and recreational activities: cinemas, theatres, stadiums, sports halls, bullrings, amusement parks, fairs, party halls, etc.
  • Meeting, work and health facilities: churches, conference and congress halls, bars, restaurants, museums, hotels, common areas of shopping centres, airports, passenger stations, car parks, educational establishments, libraries, student residences, gyms, offices with a public presence, hospitals, doctors' offices, etc.
  • Depending on the difficulty of evacuation of any premises: high-rise buildings, basements, large warehouses, etc.
  • Other premises: any premises with an occupancy capacity of more than 100 persons.

Likewise, the ITC-BT-28 indicates the obligation to have an emergency lighting system in each case. It is advisable to consult it or, alternatively, to consult the Luznor Emergency Lighting Regulations and Application Guide, available on this website.

Emergency lighting equipment must bear a marking intended to indicate its type, mode of operation, incorporated devices and rated life.

This marking must be clearly visible on the devices and must consist of a rectangle divided into four cells, each of which contains one or more positions to be filled in with figures or letters.

This lighting is intended to ensure, in the event of a power failure in the normal lighting supply, the illumination of the premises and accesses up to the exits, for possible evacuation of the public or to illuminate other indicated points.

Emergency lighting includes safety lighting, which ensures illumination during the evacuation of an area, and replacement lighting, which must enable work to be completed safely. Safety lighting can also be divided into evacuation lighting, ambient or panic lighting and high-risk area lighting.

The requirements are different for each type of emergency lighting mentioned. In addition, the REBT requires emergency lighting to be installed in certain specific locations, both with safety lighting and replacement lighting.

At the product level, the REBT covers two types of emergency lighting devices:

  • Self-contained luminaires: are luminaires providing maintained or non-maintained lighting and are characterised by the fact that the battery, the lamp, the control gear and the verification and control devices, if any, are contained within the luminaire or at a distance of less than 1 m from the luminaire.
  • Central source-powered luminaires: are luminaires that provide maintained or non-maintained lighting and are powered from a central supply system, i.e. not incorporated in the luminaire.  

The main advantages of centralized devices over self-contained devices are the simplicity of battery maintenance and the safety of the operator working at lower voltage levels. However, centralized devices have the major disadvantage that if the central source fails or the cable feeding the devices is cut or burns out, none of them will be operational. For this reason, the REBT includes more stringent installation measures for centralized devices.

Yes, Luznor makes the Luznor PCI software available to any user of the website to carry out the relevant lighting studies.
