Silent Knight SK-RELAY Intelligent Relay Module

The SK-RELAY Intelligent Addressable Fire Alarm Relay Module is designed to provide reliable relay control for compatible addressable fire alarm control panels. Featuring two isolated sets of Form C contacts, this module enables a fire alarm control panel to switch external circuits and connected equipment in response to programmed system events.

The SK-RELAY operates as a double-pole, double-throw (DPDT) relay, providing normally open and normally closed switching capabilities. Its flexible programming allows relay activation to be mapped to specific zone conditions or other supported fire alarm system events.

Each module is assigned a unique signaling line circuit (SLC) address using integrated rotary address switches. When a programmed event occurs, the fire alarm control panel sends a command to activate the relay, allowing centralized management of external equipment and control functions.

The module features a panel-controlled status LED that flashes green during normal operation and illuminates solid red during an alarm condition. The polling indicator remains visible through the cover plate, allowing technicians to monitor device communication without removing the enclosure.

Designed for straightforward installation, the SK-RELAY mounts directly into a standard 4-inch square electrical box with a minimum depth of 2-1/8 inches. Integrated SEMS screws simplify field wiring and help secure electrical connections.

Suitable for commercial and institutional fire alarm installations, the SK-RELAY provides versatile addressable relay switching for compatible fire protection and building control applications.
