Part No. F12J77175
Nittan’s modularly designed Remote Multiplex Graphic Driver Annunciators provide a large capacity of annunciation (up to 224 points) with the NFU-7000 and NFU-7000L Series Fire Alarm Control Panels. The NK-MG-32 Main Annunciator Chassis is a 32 Circuit Annunciator which may be expanded with up to four NK-AG-48 Adder Annunciator Chassis’ to a maximum of 224 Circuit Display Points. The NK-MG-32 has no buttons or LEDs on the board. Each Circuit Output will drive off board indicators such as LEDs or LAMPS on a GRAPHIC DISPLAY to form a graphic annunciator.
The drivers may be mounted by using the metal plate included in the package to any of the approved backboxes or within a graphic display. It is intended that the NK-MG-32 and the NK-AG-48 are combined with a GRAPHIC DISPLAY to make a graphic annunciator. These graphic drivers have individual lamp supervision circuitry which helps to identify burned out lamps.
