Wired doorbell 230V (Bird sounds) EKF DBW-002

The EKF call series consists of digital and analog devices. EKF Proxima digital calls exchange a unique digital code between themselves. This eliminates the situation where your call is triggered by other buttons operating on the same frequency, as is the case with analog calls. Digital technology has over a million unique code combinations available, through which devices communicate with each other. The button-receiver connection is learnable and allows for creating combinations of several buttons for one receiver and vice versa. The EKF Basic analog call line includes wired and wireless economy-class products. The main advantages of these calls are an attractive appearance and an affordable price. It is not recommended to use Basic series calls en masse in one multi-apartment building, as pressing a call button will trigger the signal in several devices simultaneously!
