Description

 

🔥 Product Introduction

The Honeywell CPU2-3030D is the primary display and central processing unit for the NOTIFIER NFS2-3030 intelligent addressable fire alarm control panel. It combines the central processing function with a 640-character backlit LCD display and QWERTY programming/control keypad.

The NFS2-3030 is an ONYX Series intelligent fire alarm control platform designed for medium- to large-scale facilities. Its modular architecture can support from one to ten Signaling Line Circuits (SLCs), with up to 3,180 intelligent addressable devices.

The referenced full-set listing includes CPU2-3030D together with ELCM-PCB and HS-NCM-W network-related hardware. Because the exact contents of a used full set can vary, the physical components, revisions, and included accessories should be verified before installation.

⚠️ This is life-safety equipment. Installation, programming, testing, and commissioning should be performed by qualified fire-alarm personnel in accordance with the applicable project requirements and local regulations.

🌐 HS-NCM-W Network Communication

The HS-NCM-W is a high-speed network communications module used with compatible NOTIFIER networked fire alarm systems.

The NFS2-3030 documentation lists HS-NCM-W and related HS-NCM variants as high-speed network communication modules capable of connecting two nodes.

In a networked configuration, the module allows compatible fire alarm nodes to exchange system information across the NOTI•FIRE•NET network architecture.

⚠️ The presence of HS-NCM-W does not by itself define the complete network configuration. Node addressing, network topology, other network modules, annunciation equipment, and system programming must be checked before commissioning.

📖 Product Usage Notes

The CPU2-3030D is not a standalone PLC-style controller. It is the primary control/display assembly of an NFS2-3030 fire alarm system.

The NFS2-3030 uses a modular architecture. LCM-320 modules provide SLCs, while LEM-320 modules expand LCM-320 functionality. The documented system can support up to five LCM-320 modules and five LEM-320 expanders for a total of ten SLCs.

Before replacing a CPU2-3030D, record:

🔹 Existing CPU part number

🔹 CPU revision

🔹 Firmware version

🔹 Panel configuration

🔹 SLC configuration

🔹 Device addresses

🔹 Network node configuration

🔹 HS-NCM-W configuration

🔹 Annunciator configuration

🔹 Voice evacuation configuration

🔹 Battery configuration

🔹 Existing alarm/trouble history

🔹 Configuration backup

VeriFire Tools can be used for NFS2-3030 programming, configuration comparison, testing, and configuration backup/transfer.
