Due to the output voltage of 48VDC in compliance with protection class III, the FZLV II system suppliesreceivers with separated extra low voltage (SELV). The use of SELV voltageensures safe operation of the system and its components in accordance with theapplicable regulations. The system is equipped with its own batteries witha capacity dependent on the load and the necessary backup time of the emergencylighting. 

The system is provided with own batteries whose capacity depends on the loadand necessary emergency lighting back-up time. It is used particularly withinthe designated fire zones.  Compact design of the cabinet allows theinstallation of the system in locations where large-size central batterysystems cannot be used. In addition, the small systems are enriched with thecasing that meets the existing visual standards.
The control panel of the system has a large touch screen to allow reading thestatus of the system, circuits and luminaires on an ongoing basis and settingany system parameters through the interface. The statuses are displayed in theform of both graphics and text. Each luminaire in the system can be assigned adescription for easy identification.

The device driver makes it possible to program and provide any configuration ofthe emergency and dynamic lighting luminaires. The user may choose from thefollowing modes: non-maintained operation, maintained operation, switched mode.It is also possible to dim the individual emergency (escape) luminaires at 1%intervals in the mains supply mode. The emergency power off delay functionallows leaving the emergency luminaires on for a preset time after the mainspower is restored. The function of automatic searching and adding luminaires tothe system does not require address to be assigned to a luminaire, as eachluminaire has its unique address.

The system has a unique IP address and RJ45 connector for its direct connectionto Ethernet. The built-in WEB module enables direct access to the system fromany computer, including the printout of the event log using any web browser. Inaddition, the system is equipped with an SD card slot (card included) to saveand upload the system settings (the so-called back up) and to save the EventLog reports according to PN-EN 50172. When saved on the SD card, the reportscan be archived and, when necessary, printed from any PC equipped with a SDslot and printer without the need to have additional dedicated software. Allsettings are stored in the device’s non-volatile memory, so they are not losteven when the system is completely disconnected from the mains and batterypower supply. The SD card is also used to update the FZLV II firmware,additional modules and emergency and dynamic luminaires. 

Lead-acid batteries with VRLA gas recombination are designed for supplying theFZLV II cabinets and their design life time is 10 years. The operatingparameters of the battery pack must comply with the technical specification,with particular regard to the operating temperature (20°C).

FZLV II system consists of:

• batteries with back-up time of 1, 3 or 8 hours
• up to 8 independent circuits, which make it possible to connect up to 20fittings per circuit. The maximum load of a single circuit is 2.5A
• controller with a display to show the current system status and configuresystem parameters
• up to 8 potential-free inputs
• 2 potential inputs to supervise the power supply circuits
• 4 control outputs
• built-in memory to record the event log
• RJ-45 connector for remote communication via LAN (BACnet, Modbus, Webserver)FZLV II system consists of:
