Alpha WRR504 4-Relay Wireless Receiver with AlphaEcall 200 System

Add reliable external annunciation and flexible device integration to your emergency call and security systems with the Alpha Communications WRR504 4-relay wireless receiver. Designed for use with AlphaEcall 200 series wireless emergency call environments, this compact intercom & entry accessory provides four programmable dry-contact Form-C outputs so you can trigger dome lamps, annunciators or third‑party monitoring equipment. The WRR504 can operate independently of master stations, creating a redundant notification path for critical surveillance and monitoring applications. Built with a tamper switch and front-panel LEDs for quick status checks, the surface-mount ABS enclosure offers a clean interior installation (6.5" x 3.5" x 1") and screw-terminal wiring with hidden access for secure connections. Programming is completed at the unit—no laptop required—helping installers reduce setup time and on-site complexity. Ideal for healthcare, assisted living, commercial security and other facilities that need dependable alarm annunciation and integration into existing monitoring or surveillance networks.
