The directory comes standard with white artwork on a dark (smoked) background. The LED indicators, one (or two) per window, are installed on a separate panel, located behind the artwork and are visible only when activated. This approach is called “backlighting.” Optional features include the following: Frontlighting, Incand- escant Lamps, Custom Grids and Custom Colors.
The unit is housed in a sturdy Brushed Aluminum frame and attached to its backbox with a vandal resistant “hidden” hinge. It has a keyed lock to prevent unauthorized access. Terminal strips (behind locked cover) facili- tate the wiring of Field Devices. Screw connectors are complete with captive wire protection and are automati- cally secured against loosening. Fire Alarm Panel driver modules can be mounted inside the annunciator panel.
The electronic components are permanently installed on circuit boards. Electrical connections from the circuit board(s) to the LED panel are made with Ribbon connectors. Normal system operation is indicated by the lighted Green LED (Power On). A Lamp Test switch is also provided. When activated, ALL system indicators should light as a demonstration that all internal circuits, wiring and LEDs are functioning properly.
The system is modular and can easily be changed.
