Description

The Bellman & Symfon Carbon Monoxide Alarm Transmitter helps protect your home by providing early warnings when dangerous CO levels are detected. It works within the Visit Smart Home System and keeps you informed through sound, flashing lights, or vibrations, depending on the receivers you have in place.


When activated, the alarm sounds loudly, flashes its indicator LEDs, and sends a wireless signal to your Visit receivers so you can respond quickly, even from another room. It uses an advanced electrochemical sensor for accurate detection and meets UL2034 residential safety requirements.


The unit runs on two long-life AAA batteries and provides clear alerts for low battery, faults, and end-of-life status. A built-in hush feature lets you silence nuisance alarms when needed while still prioritizing safety.


This transmitter is especially helpful for individuals who may not hear a traditional CO alarm. By pairing with Visit receivers, it ensures you receive alerts in multiple ways, offering dependable protection throughout your home.


With reliable sensing, strong wireless communication, and an inclusive design, the Bellman & Symfon CO Alarm Transmitter supports a safer, more connected home environment.
