Description
Never miss an important call again with the Bellman & Symfon telephone transmitter. Designed for everyday use in modern homes, this device connects to your landline and sends a wireless signal to compatible Visit receivers whenever the phone rings. It ensures you receive clear alerts through sound, bright flashing lights, or strong vibrations, especially helpful for people who are deaf, hard of hearing, or in another room.
This telephone transmitter works as part of the Visit smart alert smart security system, helping notify you about incoming calls, no matter where you are in the house. Once a call is detected, the transmitter communicates with receivers placed around your home so you can stay aware of important calls even if you cannot hear the phone ringing.
The system can also be expanded with accessories such as a contact mat, magnetic switch, or mobile sensor. When connected, the transmitter can detect additional events in your home and send alerts to the receivers in the same way it does for phone calls. This makes the device a flexible part of a broader home alert solution.
Installation is simple, and the wireless design allows the transmitter to integrate easily with other Visit components. Whether you are in another room or focused on other activities, the Bellman & Symfon telephone transmitter helps ensure that important calls and notifications are never missed.
