The frame, manufactured in aluminium, in addition to the heat sink is the support for the electronic system, the batteries and the optical group. The combined use of specific lenses and aluminium-coated reflectors ensure optimum performance in open area lighting and escape routes. Suitable for mounting on walls or ceilings. It consists of 4 or 8 LEDs with independent lenses that are illuminated if the mains fails. An internal microprocessor checks the status of the device and periodically performs functionality and autonomy tests and reports the status using the two LED indicator lights that it includes. The tests can be requested manually by means of an ON Remote Control order when connected to the mains.
