Description  The Edwards™ 4-NET-AD is a Network Adder Module for EST4 fire alarm and life safety systems. It provides two Small Form-Factor Pluggable (SFP) slots for flexible media connections and two USB ports for communication with the 4-CPU. Designed to expand networking capacity, it enables star and mesh configurations for scalable system design.     Technical Specifications  Condition New/Never Used Surplus Brand Edwards Category Fire Safety Part Number 4-NET-AD Subcategory Network Module Voltage 16 to 32 VDC Current – Standby 128 mA @ 16 VDC / 92 mA @ 24 VDC / 77 mA @ 32 VDC Current – Alarm 129 mA @ 16 VDC / 92 mA @ 24 VDC / 79 mA @ 32 VDC USB Ports 1 × USB 3.0 Type A (host), 1 × USB 3.0 Type B (device) Network Ports 2 × SFP slots (controllers sold separately) Mounting Side/back of EST4 chassis, 4-MPLT plate, annunciator enclosures Listings/Approvals UL, ULC, FM, CSFM Operating Temp 32 °F to 120 °F (0 °C to 49 °C) Relative Humidity 0 to 93% non-condensing Application EST4 life safety networking expansion Weight 1.0 lb (0.43 kg)     Information About 4-NET-AD The 4-NET-AD module is part of the EST4 system’s IPv6 self-configuring network architecture, engineered to support large-scale fire and life safety installations. It provides two SFP slots for hot-swappable network controllers, supporting fiber (single or multi-mode), twisted pair, or CAT5 cabling. This allows system designers to select the optimal physical media for project requirements. Additionally, it includes one USB Type A host port and one USB Type B device port, offering direct connectivity to the 4-CPU for both system communication and optional printer interface. Mounting options include side or back of EST4 chassis, annunciator enclosures, and dedicated mounting plates, providing flexibility in installation. Key Features: Dual SFP Ports: Accepts hot-swappable EST4 network controllers for copper, fiber, or CAT5 connections. Flexible Network Design: Supports star or mesh topologies beyond Class A or Class B limitations. USB Connectivity: Includes one USB 3.0 Type A host and one USB 3.0 Type B device port. CPU Link: Provides communication interface between SFP ports and the 4-CPU. Printer Support: USB device port may act as a printer interface. Hot-Swappable Modules: SFP network controllers can be added or replaced without power-down. Versatile Mounting: Installs in chassis, annunciator enclosures, or on a 4-MPLT plate. IPv6 Ready: Operates within EST4’s self-configuring IPv6 life safety network. High Reliability: UL, ULC, FM, CSFM listed for fire and life safety applications. Compact Form Factor: Adds networking without consuming multiple rack spaces. The 4-NET-AD provides scalable and flexible network expansion for EST4 life safety systems, ensuring secure and redundant communication.
