Alpha AC219 Annunciator Controller with Tone

The Alpha Communications AC219 Annunciator Controller with Tone works with AlphaEcall™, CM800, and SF202B series emergency call and intruder alarm systems. It provides signaling, silencing, tone-silenced visual indication, and includes an auxiliary form C signal relay.

This unit operates on 16VAC (30VA) low-voltage Class II wiring and requires a T1640 or SS106 transformer. It offers 24VDC output for accessory devices and uses positive screw terminal connections for reliable installation.

The AC219 mounts easily on finished wall surfaces or optional junction boxes. It features a built-in form C relay and generator silencer to help maintain system stability.
