Honeywell 51201803-100 Fire Safety Control Module

Overview

The Honeywell 51201803‑100 is a high-reliability Fire Safety Control Module (FSC) engineered for integration with Honeywell control systems such as TDC 3000 and UCN. Designed for safety-critical applications, it provides robust communication between Field Termination Assemblies (FTAs) and I/O processors, ensuring rapid response in fire detection and suppression systems. Its industrial-grade construction offers EMI resistance and durability in extreme environments. Certain variants function as Safety Output Modules, delivering precise discrete outputs compliant with SIL 3 standards.

Key Features

• Advanced interface for FTAs and I/O processors

• Rugged, shielded design resistant to electromagnetic interference

• Eight independent discrete output channels for safety-critical operations

• Compatible with Modbus TCP/IP (system-dependent)

• Memory capacity: 8 MB (FSC variant)

• SIL 3 certified for functional safety (IEC 61508)
