Abstract

This device receives signals from fire detectors, sends control signals to automatic closing devices such as fire shutters, and receives and displays operation confirmation signals. The number of horizontally long rectangular nameplates (district windows) on the left side of the front view can be changed by covering them depending on the installation location (see each reference front view).
