3-SSDC2 | Edwards EST Single Signature Driver Controller for Signature Series Devices

Edwards EST · PLCs & Industrial Controllers

Description  The Edwards™ 3-SSDC2 is a Single Signature Driver Controller module designed to interface between the EST3 fire alarm system CPU and Signature Series devices. It supports one Signature Data circuit and manages up to 250 intelligent detectors and 250 modules. With on-board processing, it ensures reliable loop communication, reduces noise effects, and enhances fire detection performance.     Technical Specifications  Condition New/Never Used Surplus Brand Edwards / EST Category Drives Part Number 3-SSDC2 Subcategory Control/Interface Board Type Single Signature Driver Controller Supported Devices 250 detectors + 250 modules Circuits Supported 1 Signature Data circuit Compatible Modules Signature detectors, modules, and CO detectors Processor On-board microprocessor Communication Full digital, less sensitive to wiring issues Device Mapping Automatic, non-volatile memory storage Sensitivity Modes Automatic day/night adjustment Expansion Capacity Up to 10 Signature circuits per cabinet Mounting Style Local rail mount (1 space) Terminals Removable field wiring connectors Backward Compatibility 3-SSDC, 3-SDDC, 3-SSDC1, 3-SDDC1 Application Fire alarm system device control and interface Weight 1.00 lbs     Information About 3-SSDC2 The 3-SSDC2 belongs to the EST3 Signature Driver Controller family, engineered for addressable fire alarm system integration. Each module includes its own microprocessor to coordinate communication, process information, and supervise device operation independently of the panel CPU. Installed on the local rail, it occupies one cabinet space and uses removable terminal blocks for easier wiring. This controller supports one loop of Signature Series devices, offering advanced distributed intelligence by shifting decision-making closer to the devices. It is backward compatible with earlier Signature Driver Controllers (3-SSDC, 3-SDDC, 3-SSDC1, and 3-SDDC1), making it a flexible upgrade choice. Key Features: Dedicated Microprocessor: Provides independent loop processing and communication management. Digital Communication Protocol: Less sensitive to cable characteristics, supports use of existing wiring. Loop Capacity: Supports one circuit with up to 250 Signature detectors and 250 Signature modules. Device Location Supervision: Detects missing, extra, or relocated devices and mismatched programming. Automatic Mapping: Stores both expected and actual device data, including physical sequence and “T” taps. Day/Night Sensitivity Adjustment: Automatically adapts to different environmental conditions. Multiple Survival Modes: Can continue operation in stand-alone mode if communication is disrupted. Backward Compatibility: Works with earlier SSDC and SDDC modules. Removable Terminals: Simplifies field wiring and maintenance. Supports CO Detection: Fully compatible with Signature carbon monoxide detectors. Scalability: Up to 10 circuits per cabinet (10× 3-SSDC2 or 5× 3-SDDC2). The 3-SSDC2 delivers intelligent control, enhanced supervision, and reliable loop management for Signature device networks.
