Guide to emergency luminaires

What are they?
Emergency luminaires are used for safety backup lighting when normal lighting fails due to power outages.

Why use them?
The Law and various technical standards require the presence of safety lighting in all places of work, in order to avoid discomfort and specially to ensure the security and the safety of persons, in cases of failure or power supply outages, fires or other accidents.

How to choose them?
Choosing the right emergency luminaires requires the knowledge of various types and essential characteristics.

Standard self-contained luminaires
They are ordinary emergency luminaires that turn on in case of black out.


Self-contained luminaires with inhibition device
It is possible to inhibit the emergency system functioning by utilizing the inhibition function. It is a switch which is connected to the luminaire's A and B terminals. This is a low-cost solution, but it has a disadvantage: in the event of a breakdown on the inhibition line, or if the switch is inadvertently left on the "OFF" position, the system is permanently inhibited and consequently the luminaires do not switch on.
Connection with Inhibition:

Collegamento Inhibit

For correct installation, the switch must be accessible only to staff authorized for maintenance operations.


Self-contained luminaires with Rest Mode
To overcome the inconveniences of the Inhibit function, the regulations defines the “Rest Mode” function, by which a centralized control device (Commander) is connected to terminals A and B instead of a switch. It manages the inhibition of the luminaires and keeps them active and self-restorable in the event of a blackout. If it is linked with Energy Test luminaires this fixture also allows you to carry out the functionality test of the emergency system.
Connection with Rest Mode (compliant connection):

Collegamento Rest Mode


Self-contained luminaires with self-diagnosis
The Linergy light fittings of the “Energy Test” series is equipped with a microprocessor for constant monitoring and prompt reporting of any malfunction due to a flat battery or light source.

• FUNCTION TEST: every 14 days the light fitting switches on the light source for 20 seconds to ensure its functionality
• DURATION TEST: every 84 days a power failure is simulated, the battery is completely discharged and the lamp’s nominal duration is checked

1. Remove the reflector (including the circuit board, battery and LED source/fluorescent tube) from the wall base. For the LYRA EVO, ORION, LEDY and FASTINVERTER L fixtures: open the jumper at terminals A-B
2. Wait 5 seconds
3. Reinsert the fixture reflector into the wall base. For the LYRA EVO, ORION, LEDY and FASTINVERTER L fixtures: close the jumper at terminals A-B

Note: this procedure is to be carried out on every luminaire.
Example: if you want the luminaire to carry out the tests during the morning, the procedure should be done during daytime hours (ex. 9:00)


Self-contained luminaires with self-diagnosis and touch sensor for manual test
The “Touch” version makes it possible to activate several special functions by simply touching the sensitive area of the luminaire:
• Manual start of functional and duration tests
• Memory reset
• Rest Mode
All this in addition to the standard functions of an "Energy Test" luminaire.


Self-contained luminaires with remote central supervision
The Spy System series of Linergy light fittings are self-diagnostic lamps as described above, that can be connected to and managed by their related control units.


Self-contained luminaires with wireless remote central supervision
The luminaires of the Spy System Wireless series are lamps with self-diagnosis, which can be managed and controlled by the Spy System units by means of wireless communication with mesh network technology.


Emergency luminaires with remote DALI supervision
DALI (Digital Addressable Lighting Interface) is an international standard communication protocol for the management of lighting systems, both ordinary and emergency. Click here for more information.


Self-contained luminaires for theatres and cinemas
The "Movie" range of ceiling lights are recommended for cinemas and theatres. In normal conditions, the lighting provided does disturb the show but is still able to ensure visibility of the exit routes. In the event of an emergency, the luminaire provides maximum brightness. These luminaires utilize LED technology.


Emergency luminaires supplied by Vialed Net
Luminaires compatible with the Vialed Net supply kit.


Centrally supplied luminaires
Supplied only with the power supply/driver and the light source, these are certified light fittings that can be connected to various type of emergency backup units. Generally powered at 230Vac, they are able to ensure good lighting performance.


Centrally supplied luminaires with remote central supervision
Specific series of lamps to be connected to the Spy Center emergency backup units, as they feature an internal control and monitoring module with PLC technology, and, of course, to the power supply and light source.


Centrally supplied 24V luminaires with remote central supervision
LED light fittings, with drivers and addressing and communication module connectable to Spy Center 24 series emergency backup units at extra-low voltages of 24Vdc. Each product is powered by the emergency power unit and features PLC control.


N/M (Non-Maintained)

The light is switch on only if there is the power supply to the light is disrupted.

M (Maintained)

The light remains on constantly if the power grid is operational or not. This type of operation is suitable for illuminating a pictogram to indicate the escape route.

L (Lighting)

The light fixtures are equipped with a power supply/driver and the light source, they do not have batteries. They are powered by a mains voltage or backup systems. They may have different power supply voltages according to the model; for example, 230Vac, 110Vac or 48Vdc.


The luminous flux of the lamp emitted during emergencies is a fundamental parameter. It is used, together with the radiation pattern, to design the lighting of the system. It represents the amount of light energy emitted by the source in a unit of time, the unit of measurement is the lm (lumens), and it has nothing to do with Watts, the number of LEDs or battery size. The emergency flux of the fixture always shows the emergency flux, while two fluxes are indicated for SA-type fixtures.


The degree of protection IPxx indicates the mechanical protection of the light fixture to external agents. The first digit indicates the degree of protection against the entrance of solid bodies, the second digit is against liquid; for example, IP65 light fixtures are protected against dust and water streams.


Regulations require different duration according to the various environments: 30' (minutes), 1h, 1h30', 2h. Then there are also products having 3 hours of battery life and more. The batteries must be replaced when nominal battery life is no longer ensured due to degradation.


The "Charging time" indicates the time needed to recharge the battery in order to ensure its nominal duration. As a rule, the product standard indicates a charging time of 24 hours. In various environments laws and regulations indicate devices with charging in 12h.


Linergy identifies its products by means of mnemonic codes.
Mnemonic code means a particular coding technique which allows the direct identification of the product characteristics from the code. The mnemonic code is a structured one, i.e. it follows a well defined scheme where each character, or group of characters, indicates a specific characteristic of the item.
Here follows how to read Linergy codes:
