Conventional Sounder Beacon SAB-6106 are designed for acoustic and optical fire signaling by voice. They have the ability to synchronize the emitted acoustic and optical signals within a group of signaling devices operating in one acoustic and optical space and to mute with an additional button. They are designed to work with all fire alarm control panels that provide the appropriate supply voltage at their outputs.

The main part of the signaling device is a piezoelectric transducer used to generate an acoustic signal and a LED diode with a lens placed on the head of the signaling device. The whole is placed in a housing made of non-flammable material, which consists of: a basket, a cover and a screen. SAB-6106 cooperates with the G-40SK socket, to which the power cables and optionally the synchronization cables are connected.
