Kidde SIGA-HCD Multisensor Heat CO Fire Alarm Detector

The Edwards SIGA-HCD is a commercial-grade multisensor detector designed for professional life-safety installations, combining heat detection and carbon monoxide sensing within a single field device. Engineered for use with compatible Edwards Signature Series intelligent fire alarm control systems, the SIGA-HCD addresses environments where both thermal events and the invisible threat of CO gas must be monitored simultaneously. By consolidating two critical detection technologies into one unit, it reduces the number of devices required on a loop, simplifies installation labor, and helps maintain a clean, unobtrusive ceiling appearance in commercial and institutional spaces. The detector communicates over an intelligent signaling line circuit, allowing the control panel to identify each device individually and support advanced diagnostics. It is well suited for applications such as commercial offices, hospitality facilities, healthcare environments, and any occupied space where occupant safety depends on early warning of both heat-producing fire events and carbon monoxide accumulation. For professional installers and system integrators, the SIGA-HCD represents a reliable, manufacturer-genuine component that integrates seamlessly into the broader Edwards Signature Series ecosystem, supporting compliance-driven life-safety designs.

Key features & benefits

• Dual-Threat Detection — Combines heat sensing and carbon monoxide detection in a single detector head, providing comprehensive coverage against two distinct life-safety hazards without requiring separate devices for each threat.
• Intelligent Loop Compatibility — Designed to operate on an intelligent signaling line circuit within compatible Edwards Signature Series systems, enabling point-by-point identification and centralized monitoring from the control panel.
• Simplified Installation — A single device replaces what would otherwise require multiple detectors, reducing conduit runs, wiring time, and overall installation complexity in new construction and retrofit projects.
• Advanced System Diagnostics — As an addressable device, it supports panel-level status reporting and maintenance alerts, helping facility managers and service technicians identify and respond to device-level issues proactively.
• Manufacturer-Genuine Quality — Sourced directly as an authentic Edwards component, ensuring full compatibility, consistent performance, and support for system listings and code-compliance documentation in professional life-safety designs.
• Broad Application Suitability — Appropriate for commercial, institutional, and hospitality environments where occupants must be protected from both thermal fire events and the silent danger of carbon monoxide accumulation.
