Information About HFPO-11
The HFPO-11 is part of Siemens’ line of intelligent photoelectric detectors, developed for high-performance fire detection in commercial and institutional environments. Engineered with FirePrint™ technology, it distinguishes between real fire signatures and environmental disturbances, reducing false alarms. It is a microprocessor-based detector that performs self-checks and uses tri-color LED indicators (green, yellow, red) to display operating, service, or alarm conditions. Designed for use with Siemens FS-250 panels, the HFPO-11 offers simplified installation through its plug-in base, compatibility with optional detector guards, and straightforward addressing using Siemens programming tools.
