The Siemens HFP-11 (part number 500-033290) is an addressable multi-criteria fire detector that combines photoelectric smoke sensing with thermal detection in a single device. By analyzing both smoke particle density and rate-of-temperature-rise simultaneously, the HFP-11 dramatically reduces nuisance alarms while ensuring reliable detection of both fast-flaming and slow-smoldering fires — making it an excellent choice for challenging environments like kitchens, laundry rooms, storage areas, and industrial spaces.
The HFP-11 communicates over Siemens’ addressable protocol, delivering continuous status reporting, alarm thresholds, and diagnostic data to the fire alarm control panel. It mounts to the standard Siemens DB-11 base, and its compact profile fits flush against standard ceiling surfaces for a clean, professional installation.
