Emergency lighting units

Emergency lighting systems are compulsory in many official buildings and in many workplaces so that in the unlikely event of a power failure people can find their way around safely. Safety lights and escape route lights provide enough light to shut machinery down, use the escape routes and give quick access to fire extinguishers and other safety equipment. They prevent panic and save lives.



Accu NiCd

Tridonic offers a broad range of emergency lighting units for battery powered emergency lighting systems perfectly matched to the requirements of various country-specific standards – whatever the circumstances and whatever the types of lamp.

The range comprises EM BASIC, PC COMBO, EM SELFTEST, EM PRO and EM powerLED units, covering everything from the simple to the highly intelligent, and from low-cost units to high-end solutions.

Properties for greater safety

Electrode heating, “Boost Start” and an optimised ballast-lumen factor in the emergency lighting units from Tridonic ensure optimum lamp function in emergency lighting mode. In addition, five-pole technology ensures compatibility, safety and reliability. Four relay poles switch the lamp, the fifth relay pole guarantees delayed reconnection of the control gear to the mains power supply when this returns.

This means the units are compatible with digital dimmable and non-dimmable electronic control gear.

The units can be used in permanent or standby mode. In other words, the emergency lighting units together with the ECG or CCG are either responsible for normal operation of the lamp or – if directly connected – just emergency lighting operation. The relevant versions guarantee emergency lighting for 1 or 3 hours of rated output.

The intelligent multi-level charging system from Tridonic offers “gentle operation” on the EM BASIC lp, EM SELFTEST, EM PRO and EM powerLED emergency lighting units, thereby guaranteeing long life for both rechargeable nickel cadmium (NiCd) and nickel metal hydride (NiMH) batteries.

Tridonic expertise in emergency lighting is the perfect basis for intelligent solutions.

Long equipment life

Thanks to their high-quality components, intelligent circuit design and extensive testing under rated conditions, emergency lighting units from Tridonic achieve an average life of 50,000 hours – with a probability of failure of less than 10 %; in other words, an average failure rate of 0.2 % per 1,000 hours of operation.

Constant high quality

The consistently high quality and reliability of the Tridonic emergency lighting units are guaranteed by the use of high-grade materials together with manufacturing processes certified to ISO 9001. Fully automatic manufacture ensures constant reproducible quality. All units are subjected to 100 % final testing and safety testing.

Standards and approval marks

Emergency lighting units from Tridonic are ENEC certified, carry the CE and C tick mark and meet all the European as well as international standards relating to safety, operation and electromagnetic compatibility (EMC).

Cost-effective emergency lighting

The EM BASIC units have been designed for costeffective emergency lighting systems in which all the testing and monitoring algorithms are to be performed manually. This simple solution covers the entire range of T5, T8 and compact fluorescent lamps.

The EM T5 BASIC emergency lighting unit shares the same simple design. Thanks to its low-profile casing measuring just 21 mm high, it is ideal for use in small and stylish luminaires fitted with T5 lamps.

Single-component solution

PC COMBO combines standard control gear and emergency lighting unit in one device. This greatly simplifies the wiring and installation of emergency luminaires. The one to four-lamp versions of PC COMBO for T8 and T5 fluorescent lamps provide a high degree of flexibility.

The PC CFL COMBO single-component solution is suitable for emergency lighting systems based on one or two-lamp luminaires fitted with compact fluorescent lamps.

LED emergency lighting

The EM powerLED emergency lighting ballasts in conjunction with the LED light modules are ideal for a large number of emergency lighting applications. They can be installed as a separate system or integrated in the luminaire.

Simplified testing

The EM SELFTEST emergency lighting unit with its automatic testing algorithms offers intelligence in an extremely small format. At just 21 mm high, the unit is compatible with T5 control gear. The perfectly matched range of units is designed for tubular or compact fluorescent lamps from 4 to 80 W.

In self-test mode the module uses a light-emitting diode to signal its operating status. Green means that the emergency lighting system is operating correctly. A red flashing LED indicates faulty batteries and a permanent red light indicates a lamp fault.

The test functions supported by the EM SELFTEST emergency lighting unit are continual monitoring, a weekly function test and an annual service life test. In charging mode both the charging conditions and the static battery stats are monitored.

The EM SELFTEST emergency lighting unit includes functionality for monitoring the installation phase, i.e. a period of time with an uninterrupted power supply on more than five successive days. As soon as this requirement is met the module automatically starts the commissioning and testing program. EM SELFTEST therefore complies with the commissioning test after installation prescribed in accordance with the self-test standard as per IEC 62034. This degree of automation considerably reduces the time needed for commissioning and programming the test algorithms.

Combination of emergency lighting and DALI

The special feature of EM PRO units from Tridonic is that they can be operated as individual systems or can be successfully integrated in DALI-based lighting systems. This means that the entire functionality of DALI systems can be accessed, including individual addressability.

Individually addressable emergency lighting units have a certain level of “intelligence”. In these cases, the fault reporting function provides more information than simply that the lamp, control gear or battery is faulty. Detailed information on, say, the type of lamp or device status can be displayed either locally or centrally. This extensive functionality of EM PRO emergency lighting units, which also have the “capabilities” of the EM SELFTEST module, has benefits in terms of facility management, particularly for operating large lighting systems.

Intelligent charging system

The intelligent multi-level charging system from Tridonic ensures that the charging behaviour is tailored to the particular battery type. As its name suggests, the multi-level charging system has three different charging cycles, namely initial charge, power charge mode and trickle charge mode.
