Edwards SIGA Addressable Modules: SIGA-IS, SIGA-CT2 & SIGA-CC1 Guide
Overview
Edwards SIGA addressable modules, specifically the SIGA-IS, SIGA-CT2, and SIGA-CC1, are integral components of modern fire alarm systems. These modules facilitate targeted and efficient communication between detectors and the control panel, ensuring rapid response and precise location identification during fire events. Addressable modules such as the Edwards SIGA modules play a critical role in system scalability and integration with other components like the Edwards Security Light Dock Base 101BS-E1.Specifications
Each Edwards SIGA addressable module has distinct specifications that cater to various functionalities within a fire alarm system. Below is a detailed specifications table for the SIGA-IS, SIGA-CT2, and SIGA-CC1 modules.| Model | Function | Operating Voltage | Current Draw | Protocol |
|---|---|---|---|---|
| SIGA-IS | Input Module | 24 VDC | 0.5 mA | IDNET |
| SIGA-CT2 | Control Module | 24 VDC | 1.5 mA | CLIP |
| SIGA-CC1 | Command Module | 24 VDC | 1.2 mA | SLC |
When configuring your Edwards SIGA modules, ensure all connections are secure and double-check the address settings to prevent communication errors.
Installation and Wiring
The installation of Edwards SIGA modules requires careful attention to wiring classes and system architecture. The SIGA-IS and SIGA-CT2 modules are commonly wired in either Class A or Class B configurations. For Class A wiring, ensure that the loop returns to the panel, providing a redundant path in case of a single break. Class B wiring, while simpler, does not offer the same redundancy, so it should be used where system simplicity is preferred over resilience. Proper installation also requires adherence to device-specific mounting and environmental considerations. The SIGA-CC1, for instance, should be mounted in a location that allows for easy access and maintenance, while also being protected from moisture and extreme temperatures.Communication Protocols
Edwards SIGA modules utilize various communication protocols that determine their integration and functionality within the fire alarm system. The IDNET protocol, used by the SIGA-IS, offers a stable and reliable communication pathway for input signals. For the SIGA-CT2, the CLIP protocol ensures efficient data transmission, minimizing latency and maximizing system responsiveness. The SIGA-CC1 utilizes the SLC protocol, which supports a greater number of devices and allows for extensive system scalability.Always verify compatibility with your fire alarm control panel's protocol before integrating new modules to avoid communication failures.
Certifications and Standards
Compliance with industry standards is essential for ensuring the safety and reliability of fire alarm systems. Edwards SIGA modules are certified under UL 268 and FM standards, which guarantee that these devices meet rigorous safety and performance requirements. UL 268 covers smoke detectors and their performance criteria, while FM certification ensures that the modules are reliable and meet international safety standards.FAQs
Addressing is typically done using DIP switches or software configuration. Refer to the installation manual for specific instructions.
Yes, both Class A and Class B wiring configurations are supported, though Class A is preferred for its redundancy.
The number varies by system, but typically an SLC loop can support up to 250 devices.
Regular testing and inspection as per NFPA standards are recommended to ensure optimal performance.
