Ex-Recess-mounted ceiling emergency light fittings in metal design

eLLB 20… V-CG-S / eLLB 20… NIB

(Zone 1, 2, 21, 22)

The Ex recess-mounted ceiling emergency lighting eLLB 20 fittings are equipped with EVG 09 electronic ballasts and are suitable for two-pin fluorescent lamps. These light fittings are used for surface and flush mounting in ceilings, in particular in clean rooms where smooth, flush surfaces are very important. They are often used in the pharmaceutical and chemical industries, and experimental facilities, as well as in paint shops and spraying cabinets.

Description

Designed for easy installation

The housing is made of white-painted steel sheet with an integrally moulded cover frame or, optionally, of polished stainless steel. It is installed securely in the ceiling by means of special fixing elements that allow a universal and simple mounting in recessed clean room ceilings that are 25 to 90 mm thick. In addition, it can also be fixed by means of two M8 drilled holes in the top of the housing. The hinged, frameless pane made of safety glass is fixed with captive screws and has inside hinges. The sealing material is guaranteed silicone-leak-proof. Together with the generously dimensioned terminal compartment, the standard, double-ended through-wiring allows a cost-saving installation.

With central monitoring

Safety is always our top priority. This is why we also supply the eLLB 20 recessed ceiling mounting light fitting series with a built-in V-CG-S module. These luminaires with individual monitoring can be connected to a CEAG emergency lighting supply system and, in the event of an emergency, they provide a reliable illumination of your safety and escape routes.If you need a reliable and decentralised emergency lighting Emergency lighting eLLB 20 NIB luminaires with a self-contained battery system provide a decentralised solution for the mandatory emergency lighting, independent of central systems. In large plants, in particular, these luminaires offer significant cost benefits.

More safety due to sophisticated micro-electronics

Thanks to a new charging and monitoring technology with intelligent microelectronics, the NIB emergency lighting luminaires provide reliable safety and reduced maintenance costs. A function test lasting 5 minutes, that is carried out automatically on a weekly basis, even during mains operation, and a quarterly partial duty-cycle test provide additional safety. and drastically reduce the necessary amount of manual tests. The charging and discharging functions are monitored constantly by the micro-processor and are indicated via a diode display. Only the spent energy is recharged – therefore, overcharging is not possible. The so-called memory effect cannot occur – the service life of the battery is optimized.

The need to replace a battery, a fault in the emergency lighting circuit or a faulty battery is indicated by the LED display. Due to a new type of battery connection, the battery can be replaced in the hazardous area. The emergency lighting cycle can be set locally for 1.5 or 3 hours. A remote switch inquiry is possible in conjunction with the twin-ended through-wiring. The separate battery housing can be mounted directly onto the light fitting or it can be recess-mounted up to 1.5 m away, depending on the ceiling raster. Connection is made using eXLink connectors and no tools are required.

Long-term safety

The recess-mounted ceiling luminaires of this robust lighting series with plastic enclosure are equipped with a highly-efficient electronic ballast, which has a reliable EOL circuit. Thus, the lamps are checked for proper operation and shut down safely in the event of a malfunction at the end of the service life. In addition, the dual-channel structure of the electronic ballasts allows the safe operation of the second lamp if one lamp fails.
