Buzzer 230V, 4VA DM340 004113

Modular acoustic signaling module for electrical installations

The modular buzzer is a compact signaling device designed to work with a doorbell button - it informs of a guest's arrival or signals a selected event in the installation. Mounted directly in the electrical distribution board, it is suitable for both residential buildings and public utility facilities.

The device operates at a voltage of 230 V AC, allowing for direct connection to standard single-phase installations - without the need for an additional transformer. A current consumption level of 27 mA (approximately 6 VA power) means minimal circuit load, while simultaneously guaranteeing an immediate response upon activation.

Acoustic signal and construction

The buzzer generates a continuous tone with a sound pressure level of 73 dB - sufficiently clear to draw attention even in noisy environments, yet not exceeding the limit of discomfort. The plastic housing ensures durability and resistance to the conditions inside the distribution board.

Mounting and connection

The mounting method is built-in - the device is installed directly into the electrical panel on a standard DIN rail. Connection is carried out via screw terminals, which allow for secure wire fastening and facilitate any necessary maintenance. The absence of a built-in transformer simplifies installation and reduces the dimensions of the device itself.

Operating parameters

The housing protection degree IP00 means that the device is adapted for operation inside a distribution board - in a dry environment protected from direct contact with moisture or dust. For installations requiring a higher degree of protection, additional enclosures or panel covers are used.
