Silent Knight SK-ZONE Addressable Zone Interface Module

The SK-ZONE Intelligent Addressable Zone Interface Module is a fire alarm monitoring device designed to connect compatible conventional two-wire smoke detectors to an intelligent addressable fire alarm control panel. Featuring supervised zone monitoring, rotary address switches, and support for Style B and Style D wiring configurations, this module provides a practical solution for integrating conventional smoke detection circuits into addressable fire alarm systems.

The SK-ZONE allows a compatible fire alarm control panel to monitor an entire zone of conventional two-wire smoke detectors through the signaling line circuit (SLC). Rather than assigning an individual address to each conventional detector, the module communicates the status of the monitored zone to the addressable control panel.

The module reports three primary zone conditions: normal, open, and alarm. Its supervised design monitors both the conventional detector circuit and the connection to the required external power supply.

The SK-ZONE supports Style B and Style D initiating circuit wiring configurations, providing flexibility for compatible fire alarm system installations. All connected conventional two-wire smoke detectors must be specifically listed as compatible with the SK-ZONE.

Integrated rotary address switches allow installers to assign the module's SLC address during system configuration. A panel-controlled status LED flashes green during normal operation and displays solid red during an alarm condition.

For convenient wiring, the module features SEMS screw terminals. It mounts directly into a standard 4-inch square electrical box with a minimum depth of 2-1/8 inches. An optional SMB500 surface mounting box is available for installations requiring a separate enclosure.

Designed for compatible 5000 and 6000 Series addressable fire alarm control panels, the SK-ZONE provides a reliable interface between conventional smoke detection zones and intelligent fire alarm monitoring systems.
