Answer:
The DS-PMA-WBELL utilizes two-way 433 MHz RF communication protected by AES-128 encryption with collision prevention, backed by an integrated physical tamper switch to detect unauthorized removal or enclosure disassembly.
The DS-PMA-WBELL provides continuous two-way supervisory communication with the alarm controller to maintain system integrity:
- AES-128 Data Encryption: Encrypts two-way RF wireless payloads between the siren and control panel, preventing signal interception and replay attacks.
- Collision Prevention: Incorporates wireless data anti-collision algorithms to maintain reliable packet delivery in environments with active RF traffic.
- Tamper Alarm Switch: Protects against physical vandalism, dislodgement from mounting surfaces, or unauthorized enclosure opening by immediately relaying a tamper alarm event to the host panel.
