The Signature Optica Series SIGA-OSHD smoke detector combines advanced optical sensing technology with a practical design that increases efficiency, saves installation time, cuts costs, and extends life safety and property protection capabilities.
Continuous self-diagnostics ensure reliability over the long haul, while environmental compensation helps reduce maintenance costs.
The SIGA-OSHD provides an optical smoke sensor and a rate-of-rise heat sensor with a fixed temperature setting. Together, these sensors efficiently detect smoldering and fast-flaming fires.
Like all Signature Optica Series detectors, the SIGA-OSHD is an intelligent device that gathers analog information from multiple optical sensors, converting this data into digital signals. Utilizing dual optical wavelengths combined with multiple detection angles, the SIGA-OSHD differentiates particles not representative of actual smoke.
Particle data is input into digital filters which feed a series of ratios removing signal patterns typical of nuisance sources, thus reducing unwanted alarms. To make an alarm decision, the detector’s onboard microprocessor measures and analyzes all-optical sensor readings and compares this information to preprogrammed settings.
