Bellman Transmitters
Transmitter detect key events and send a signal to trigger your receivers. Must be used alongside a new or existing receiver.

When every signal matters.
Bellman Transmitters detect important events and wirelessly signal your receivers, which then alert you with sound, light, or vibration. It all happens in seconds, with no setup or apps required.
What does a transmitter do?
Each transmitter detects a specific event, like a doorbell, phone call, or smoke alarm and sends a wireless signal to your Bellman receiver, which then alerts you with sound, light, or vibration.
Can I mix different transmitters?
Yes. The alerting system is fully modular. You can use multiple transmitters together and customize your system based on your home and needs.
Can a transmitter work by itself?
No. Transmitters are designed to send signals, but they need a compatible Bellman receiver to deliver alerts. The receiver is what notifies you through sound, light, or vibration when the transmitter detects an event.
How do I set it up?
There’s no setup required. All components in the bundle come pre-paired and ready to use right out of the box. Just plug them in (or insert the batteries), place them where needed, and you’re ready to go.
