The Graphic Annunciator is housed in a sturdy Brushed Aluminum frame and attached to its backbox with a
vandal resistant “hidden” hinge. It is key-lockable to prevent unauthorized access.
Terminal strips (behind locked cover) facilitate the wiring of Field Devices. Screw connectors are complete with
captive wire protection and are automatically secured against loosening.
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. Fire Alarm Panel driver modules can be
mounted inside of the annunciator panel.
Normal system operation is indicated by the lighted Green LED indicator. A lamp test switch is also provided.
When activated, ALL system indicators should light as a demonstration that all internal circuits, wiring and
LED’s are functioning properly.
The system is modular and can easily be changed or expanded. Must be installed with U.L. Listed equipment.
