Hochiki (SOC-24DH) Soc-24dh photoelectric smoke detector (head only)

The Hochiki SOC-24DH photoelectric smoke detector represents a precision-engineered solution for advanced fire detection in commercial and institutional environments. Designed specifically for addressable fire alarm systems, this detector head provides reliable, early-stage smoke detection through sophisticated optical sensing technology. Engineered to integrate seamlessly with Hochiki addressable panels and compatible fire alarm networks, the SOC-24DH delivers professional-grade performance in high-traffic and mission-critical spaces.

Utilizing state-of-the-art photoelectric sensing technology, this detector excels at detecting slow, smoldering fires that produce significant smoke before open flame emergence. Its advanced optical chamber efficiently distinguishes between genuine fire conditions and nuisance environmental particulates, reducing false alarm potential in complex settings like office buildings, healthcare facilities, educational institutions, and industrial environments.
