Description
The Silent Knight SD505-6RB 6″ Relay Base is a compact, reliable, and addressable relay module designed to enhance your fire alarm system with flexible control options. It provides a Form C contact rated at 8.0 amps for 240 VAC, 120 VAC, and 30 VDC—perfect for activating auxiliary devices such as elevator recall systems, fan shutdowns, magnetic door holders, or additional notification appliances.
This intelligent relay base integrates seamlessly with SD505 series detectors including the SD505-APS, SD505-AIS, and SD505-AHS, and mounts easily to a standard single or double gang electrical box. It communicates over the system’s SLC loop, yet does not require an additional address, making it an efficient and cost-effective solution.
Engineered for both style 4 and style 6 supervision, the SD505-6RB ensures fully supervised operation, allowing it to maintain high system integrity in critical life safety applications. Like all Silent Knight devices, it’s UL listed, offering code-compliant performance you can trust.
