The APWK-LED button has optical and acoustic signaling. Optical signaling is provided by LED diodes. LED indicators can have two colors - green (normal state) or red (alarm state). The operation of the red LED can be set in one of three ways - on / off / flashing. It is also possible to set the operating mode of the acoustic signaling - silent / intermittent / continuous and to set the intensity of the generated sound.
