433Mhz Tuya Smart Wireless Home Alarm Siren — Motion & Door Sensor Compatible, 110dB High Volume

433Mhz Tuya Smart-compatible wireless siren for home security, designed to work with motion and door sensors. The system is expandable — you can add extra accessories or additional alarm hosts to cover more areas. A single sensor can pair with more than two siren alarm hosts, allowing devices to be positioned in different rooms or zones. Alarm duration is fully configurable so you can set how long the siren sounds. The unit supports local arming modes: disable the alarm while at home and enable it when you’re away. The siren produces a 110dB alert; the sound level is fixed and cannot be muted or adjusted. Maximum working distance between a host and its accessories is 100M (open space), giving wide coverage for typical residential layouts.
