Silent Knight 6820UEVS Ultra Series Intelligent Addressable Fire Alarm Control Panel with Emergency Voice System

The 6820UEVS Intelligent Addressable Fire Alarm Control Panel with Integrated Emergency Voice System is a comprehensive life-safety solution designed to combine advanced fire detection, alarm notification, emergency voice evacuation, and mass notification capabilities in a single enclosure.

Designed for commercial, institutional, and large-building fire protection applications, the 6820UEVS integrates an intelligent addressable fire alarm control panel with an emergency voice system (EVS), allowing authorized personnel to coordinate fire alarm operations and emergency announcements from one centralized system.

The control panel features a built-in signaling line circuit (SLC) capable of supporting up to 159 compatible detectors and 159 compatible modules using SK protocol, or up to 127 devices using SD protocol. Additional SLC loops can be installed to expand the system to a maximum capacity of 1,110 SK protocol points or 635 SD protocol points, depending on the installed system configuration.

Its integrated emergency voice functionality includes an onboard supervised microphone, dedicated message controls, and selectable output group activation. All-call and non-active call buttons allow operators to quickly select the appropriate notification groups for emergency announcements.

The system supports up to 15 recordable emergency voice messages, each up to one minute long, with messages assignable to eight EVS buttons. Emergency voice messages can also be configured to take priority over fire alarm messages when required by the system's emergency response procedures.

Eight onboard Flexput circuits provide configurable outputs for compatible notification appliances or auxiliary power applications. The panel also supports selectable strobe synchronization for compatible notification devices and can generate 520 Hz low-frequency alarm tones for applicable notification requirements.

Designed with integrated communications capabilities, the 6820UEVS includes a digital alarm communicator transmitter (DACT), IP reporting support, and optional cellular communication capabilities.

The 6820UEVS is identified as a direct replacement for the 6820EVS and 5820XL-EVS fire alarm control panels, offering expanded system capacity and integrated emergency communication capabilities for modern fire protection installations.
