Notifier NCA-2 Network Control Annunciator Instruction Manual

1. 서론

The Notifier NCA-2 Network Control Annunciator is a sophisticated device designed for use in fire alarm and emergency communication systems. It provides a 640-character display for monitoring and controlling network systems. This manual provides essential information for the proper installation, operation, and maintenance of the NCA-2 unit.

When used with single panel NFS2-640 systems, the NCA-2 can serve as the primary display, connecting directly to the CPU2-640. For network systems involving two or more Fire Alarm Control Panels (FACPs), one network display (NCA-2, NCS, or ONYXWorks) is required per system, and each NCA-2 must connect to and utilize an NCM Network Control Module.

Installation of the NCA-2 unit requires adherence to local codes and the National Fire Protection Association (NFPA) standards. It should only be performed by qualified personnel.

3.1 장착 옵션

The NCA-2 offers flexible mounting solutions:

• Direct FACP Node Mounting: The unit can be mounted directly in a row of a Fire Alarm Control Panel (FACP) node.
• Annunciator Module Positions: It can occupy two annunciator module positions within a compatible enclosure.
• Specific Mounting Kits:
  • NCA/640-2-KIT: For direct mounting to the CHS2-M2 chassis.
  • CA-2, ADP-4B: Other compatible mounting plates or kits.
• Annunciator Box Installation: Can be installed in an annunciator box, such as the ABS-2DB (requires the CHS-2D chassis).

3.2 전기 연결

Ensure all power is disconnected before making any electrical connections.

• Single Panel Systems (NFS2-640): The NCA-2 connects directly to the CPU2-640 for primary display functionality.
• Network Systems (Multiple FACPs): Each NCA-2 unit requires an NCM Network Control Module for connection to the network. Refer to the NCM module's instruction manual for specific wiring diagrams and configuration.

Always follow the detailed wiring diagrams provided with the NCA-2 and associated modules. Incorrect wiring can lead to system malfunction or damage.
