Alpha AC219 Annunciator Control Unit for Alphaecall and CM800/DS100

Designed for reliable site-wide alerting, the Alpha Communications AC219 annunciator control unit streamlines alarm and emergency-call monitoring for commercial and institutional installations. As an annunciator module built specifically for AlphaEcall™, CM800 and DS100 systems, the AC219 centralizes audible tone generation, tone-silenced visual indication and manual tone-silencing to cut response time and reduce confusion during events. The unit operates on 16VAC Class II low-voltage power and provides a convenient 24VDC output for accessory devices, eliminating the need for separate power modules. Integrators will appreciate positive screw terminal connections and a Form 'C' auxiliary relay for straightforward interfacing with access control, intrusion alarm panels and building management or surveillance systems. Housed in a compact plastic enclosure, the AC219 delivers dependable performance for security, monitoring and intercom applications where clear signaling and flexible integration matter. Add the AC219 to your AlphaEcall or CM800/DS100 deployments to simplify wiring, improve alarm visibility and ensure consistent site-wide notifications — contact your distributor to specify the unit for your next security or emergency-call project.
