The WT Series annunciator is designed for outdoor use and in locations where protection from water and temperature extremes are needed.
The annunciator is housed in a rugged #16 gauge steel enclosure and door, dip primed and finished in a Taupe Powder Coat Enamel. The door is attached with a vandal resistant, hidden hinge with a key locked cover to prevent unauthorized access. The door has a continuous 1/2” close-cell neoprene gasket and the annunciator window opening uses the Scotch VHB joining System sealing gasket to seal the annunciator window opening.
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. Fire Alarm Panel driver modules can be mounted inside of 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 in 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.
