Description
The Silent Knight SK-RELAY is an intelligent, addressable relay module designed for seamless integration with Honeywell Silent Knight fire alarm control panels (FACPs). Equipped with two isolated sets of Form C contacts (DPDT), this versatile module enables the panel to control discrete circuits, such as door holders, fan shutdowns, elevator recall, or auxiliary functions.
The SK-RELAY features rotary address switches for quick configuration and panel-controlled LED indicators for status feedback—green for normal operation and red for active alarm. Easily mounted in a standard 4” square or optional surface-mount electrical box, the SK-RELAY simplifies installation while maintaining full flexibility in relay programming. It is UL listed for commercial fire protection applications.
