The NFA-T01LC is a dual-loop expansion card designed to increase the loop capacity of a control panel. Each loop supports up to 254 addressable NFA-compatible devices, including optical smoke detectors, heat detectors, call points, modules, and sounders, in any combination. The transmission path is fully monitored, ensuring that any short or open circuit faults are detected and reported individually for each loop. The card also features built-in DC surge protection, capable of withstanding up to 4kA lightning current. Designed for panel mounting, the NFA-T01LC can be installed in any available loop port, with the control panel automatically assigning the loop number upon power-up.
