PATLITE Corporation released the BKV series panel-mount MP3 compatible audible annunciator that produces the high sound pressure of 95dB at 1 meter with low profile housing.

Audio data is field-programmable with an optional SD card. Total recording time of 63 seconds (at 64kbit/s) can be divided into 5 channels by bit input or 31 channels by binary input.

Sound volume and playback mode also can be changed by rotary switches stored behind the front cover even after installation.

Front panel color is available in ivory white and dark gray depending on the color of machine / control panel.
