Rectangular shape with the possibility of a flush mounted adjustment. It has an LED light source that can be turned on/off as desired with an independent input (LUM input). The same light source will provide lighting for a certain amount of time if the Mains voltage fails. An internal microprocessor checks the status of the device and periodically performs functional and autonomy tests, reporting on their status by means of a dual-colour LED. Can simulate a normal power fault using a start button in the luminaire or a remote control order (inlet TELEM).
