The Directory Annunciator is used for applications where the detail of the Graphic Annunciator is not required, usually in smaller buildings. The Directory Annunciator has a grid or matrix style design. With the grid design, a Led in placed in each legend section, and is accompanied with a device location or zone clarification. Also, with the grid design, the panel can be manufactured with a blank grid, or with a printed grid. With the matrix design, the floors of the Annunciator are usually shown on the vertical axis, and the device types are shown on the horizontal axis. LEDs are provided within the matrix, where applicable.
The Directory / Matrix Annunciators are usually accompanied by a Graphic Map. Please see our Graphic Map section, for more information.
The main advantage of the Directory / Matrix Annunciator is that it is a simpler design than the Graphic Annunciator, and is less expensive.
