The Edwards SIGA-OSCD smoke detectors have been at the forefront of detection technology for over a decade. The SIGA-OSCD is a smoke and carbon monoxide detector known for its advanced technology, providing unparalleled life safety measures for any property.
Only the Signature Optica Series integrates a patented optical smoke sensing with life-saving CO detection, offering dual protection by sensing both visible smoke and invisible, odorless CO gas. Furthermore, the SIGA-OSCD uses multi-criteria optical sensing to rapidly respond to a wide range of fires, from extremely fast flaming polyurethane fires to slow-burning combustibles. All the while, it enhances detection sensitivity and minimizes false alarms from cooking smoke and similar disturbances by differentiating between common nuisance particles.
In today’s complex environments, fire and life safety demand more than just basic smoke detection. You need intelligent technology that adapts, responds, and protects without compromise. That’s exactly what you get with the Edwards SIGA-OSCD, the flagship detector of the Signature Optica Series.
The SIGA-OSCD is fully compliant with the UL 268 7th Edition standard—one of the most rigorous updates to smoke detector testing in decades. This standard introduces new test methods to simulate a wide range of real-world fire scenarios. For these standards, the OSCD’s has been tested to comply with standardized smoke growth patterns, including various beam and MIC profiles. These profiles assess a detector’s ability to recognize both slow-smoldering fires and rapid-flaming polyurethane fires, helping to improve escape time and save lives.
What truly sets the SIGA-OSCD apart is its intelligence. With five sensitivity settings, two levels of environmental compensation, and twenty pre-alarm settings, you can customize your device for your specific needs and use cases. Even more, continuous self-diagnostics provide ongoing checks and automatic alerts, including a convenient “end of life” warning for timely replacement.
The device also features built-in ground fault detection, and a base with an integrated fault isolator for use on Class A circuits. It’s fully compatible with signature loop controllers, making it easy to retrofit into existing systems without rewiring. Offering full protection from life-endangering hazards, the SIGA-OSCD is ideal for protecting life in the busiest industries, like hospitality, industrial facilities, business, healthcare, and education.
The Edwards SIGA-OSCD delivers intelligent, dual-threat detection in a single, powerful device—combining advanced smoke and CO sensing with industry-leading nuisance alarm resistance. Fully compliant with UL 268 7th edition and engineered to meet real-world fire scenarios, it’s the trusted choice for life safety across today’s most demanding environments.
