EDWARDS INTELLIGENT MULTI-CRITERIA OPTICAL SMOKE AND HEAT DETECTOR, 135F W/15F/MIN ROR, UL/ULC
The Signature Optica Series SIGA-OSHD smoke detector brings advanced optical sensing technology to 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 fires, as well as fast flaming fires.
