What it is
Summary
AI-generated from vendor-published content · April 26, 2026
The KA300TX is a wireless transmitter that attaches to the siren of an existing alarm — such as a smoke detector or carbon monoxide detector — and sends a signal to a compatible Krown receiver when that alarm goes off. It's designed for people who are deaf or hard of hearing and need a way to be alerted to household emergencies through visual (strobe) or tactile (bed shaker) alerts rather than sound. This transmitter is one piece of a larger alerting system: it requires the Krown KA300RX Alarm Monitor Receiver to do anything useful, and that receiver unit is sold separately. This transmitter only works with compatible Krown KA300-series receivers — it won't pair with other brands or the Krown weather alert system, which uses a different transmitter.
