The K-RLED24R adds 24 zones of LED annunciation to any Kidde Commercial R-Series remote annunciator without running new NAC circuits. It connects to the FACP over RS-485, supports cable runs up to 4,000 ft on standard twisted pair, and gives fire installers zone-level alarm and trouble visibility right where building management needs it.

Compatible with the full Kidde Commercial intelligent panel lineup - EVOLVE, VS1, VS4, FX64, FX1000, and VM systems. RS-485 communication supports Class B, Redundant Class B, and Class A wiring configurations at baud rates from 9,600 to 115,200. UL, ULC, and FM listed. Mounts on a standard 4-inch square electrical box.
