Sirens with radio frequency connection 433 – 434 MHz

433 – 434 MHz

— the operation of devices at their own frequency (in our case, 433 – 434 MHz) enhances the reliability and security of the system, as it reduces the likelihood of interference from other wireless devices with close frequencies. When selecting based on this parameter, it is important to consider equipment compatibility, standards, and licensing requirements (to avoid potential legal violations).
