FERMAX 8819 | chalet audio changer

Villa audio changer. Changers are necessary in installations with more than one access. Its function is to connect the home telephone with the panel from where the call is being made. This changer has been designed for 1-line door entry panels (4+n analog system). Maximum 5 accesses. 1 changer is required for each goalkeeper access. Only in case of 2 entrances, 1 changer is needed. It selects the origin of the call, allowing communication only with the panel through which the call was made and the activation of the corresponding lock release. Small in size, they allow their installation in electrical registers. They can be embedded in standard 10x10 cm boxes. They have adhesive strips for fixing, or they can be screwed directly to the wall.
