Network Control Module 300 Series Technical Bulletin
Unless otherwise specified, the information in this technical bulletin
refers to all NCM models in the NCM300 Series.
NCMs described in Table 1 require Metasys Release 8.0 software or
later except for the NU-NCM300-0, which requires Release 6.0 or
later, and the NU-NCM350-8, which requires Release 9.01 or later to
use all 8 MB of memory. When using Release 10.0 or later, the
WINCSETUP Information view shows the NCM350-8 with 6 MB
RAM before a download and 8 MB RAM after download. The
problem occurs within the flash memory program code; the
NCM350-8 is not faulty (maintains 8 MB memory throughout
download).
An NCM, via the N1 LAN, also has the ability to control activities for
objects located in other NCMs. An example of exchanged control
would be objects shed or restored by the Demand
Limiting/Load Rolling feature.
Different program sets download to an NCM to support a variety of
devices on its local bus. The program sets are of two types: Standard
Functionality and Migration Functionality. The Standard Functionality
supports one of the following applications:
• Standard NCM software supports: NEU devices (XMs, DCM),
Heating, Ventilating, and Air Conditioning (HVAC) devices such
as Air Handling Units (AHUs), Variable Air Volume (VAV)
controllers, Variable Air Volume Modular Assemblies (VMAs),
Unitary (UNT) controllers, Lab and Central Plant (LCP)
controllers, DX-9100s, Intelligent Fire Controller (IFC) panel,
Extension Modules (XTM), Generic Vendor Devices (VNDs),
Metasys Integrator® units, and lighting application specific
controllers. For details, see NCM Software Options Technical
Bulletin (LIT-636023).
• Fire Management software integrates the fire alarm system
IFC panel (IFC-2020 or IFC-1010) to the Metasys network, as well
as supporting XMs and HVAC devices (listed above) on the
N2 Bus. In this configuration, the IFC panel operates as a
stand-alone fire alarm system, the NCM is part of the Metasys
Intelligent Fire Network, and is not UL Listed for fire alarm
(UOJZ) or for smoke control (UUKL) applications. The NCM
connected to the IFC panel serves as an ancillary annunciation link
between the IFC panel and the Metasys system.
Note: If you are using the Fire-Net NCM on the Metasys
Intelligent Fire Network, refer to Appendix A: Fire-Net NCM in this
document for details on the software used with the Fire-Net NCM.
