The Siemens (HFP-11) Smoke Detector (500-033290) is a plug-in, two-wire and multi-sensor detector (with both photoelectric and thermal inputs) that is compatible with Fire Finder XLS and FS-250 series of control-panel systems. Each detector consists of a dust-resistant, field-cleanable and photoelectric chamber; a solid state, non-mechanical thermal sensor, and microprocessor-based electronics with a low-profile plastic housing. Model HFP-11 utilizes state-of-the-art ASIC circuitry and surface-mount technology for maximum reliability.
Every Model HFP-11 fire detector is shipped with a protective dust cover. Model HFP-11 utilizes an infrared light emitting diode (IRLED), and light-sensing photodiode. Under normal conditions,
light transmitted by the LED is directed away from the photodiode and scattered through the smoke chamber in a controlled pattern.
The Siemens (HFP-11) Smoke Detector’s microprocessor uses an integral EEPROM to store the detector’s address and other critical operating parameters, which include the assigned program values for Alarm and Trouble thresholds. Communication within the detector, as well as between the HFP-11 and the control panel, or with Model DPU (field device programmer / test unit), are supervised and safe-guarded against disruption by reliable, microprocessor-based error checking routines.
Additionally, the micro-processor supervises all EEPROM memory locations, and provides a high degree of EEPROM-failure fault tolerance. Model HFP-11 determines its operating status to be Normal in Alarm or in Trouble modes, depending on the difference between the alarm threshold values stored in the detector’s memory and the detector’s latest analog measurement.
