Answer:
The DS-PMA-WBELL is engineered to integrate wirelessly with 433 MHz Hikvision intrusion alarm hubs and wireless security control panels supporting two-way RF pairing.
The Hikvision DS-PMA-WBELL siren operates exclusively over 433 MHz two-way RF protocols, making it compatible with Hikvision 433 MHz intrusion security panels and alarm control hubs.
Enrollment is completed via the host panel's two-way RF registration process. For reliable operation, field engineers should verify RF signal strength at the intended installation site prior to permanent surface fixing and avoid mounting directly onto large metallic surfaces that attenuate 433 MHz transmissions.
