Information About 3-SDC1
The 3-SDC1 is part of the Edwards Signature Series intelligent fire alarm platform and functions as a Signature Data Circuit expansion card for compatible Signature Driver Controller modules. When installed on a Single Signature Driver Controller, it upgrades the controller to Dual Signature Driver Controller functionality by adding a second intelligent signaling line circuit. Each signaling circuit supports up to 125 Signature Series detectors and 125 Signature Series modules while providing automatic electronic addressing, device mapping, and advanced diagnostics. Designed for EST3 and compatible Edwards fire alarm systems, the module supports Class A, Class B, and Class X wiring configurations while maintaining dependable communication throughout the life safety network.
Key Features:
- Signature Data Circuit Expansion: Adds one intelligent Signature signaling line circuit to compatible controller modules.
- Intelligent Device Support: Supports up to 125 Signature Series detectors and 125 Signature Series modules on a single circuit.
- Driver Controller Upgrade: Converts a Single Signature Driver Controller into a Dual Signature Driver Controller when installed.
- Flexible Wiring Classes: Supports Class A, Class B, and Class X signaling line circuit configurations.
- Automatic Device Mapping: Performs electronic addressing and automatically stores device location information.
- Distributed Intelligence: Communicates with Signature Series devices using intelligent digital communication protocols.
- Simple Installation: Plugs directly into compatible controller modules with removable field wiring terminals.
- Conventional Smoke Detector Support: Provides resettable 24 Volt Direct Current output for compatible two-wire smoke detector circuits.
The 3-SDC1 delivers the reliability and precision required for expanding intelligent addressable fire alarm systems with advanced Signature Series communication.
