Siemens HFP-11 Smoke Detector Head

Description

MSIEMENS HFP-11 ADDRESSABLE SMOKE DETECTOR. **NEW IN FACTORY BOX**.
Product Overview:
The Siemens Model HFP-11 utilizes advanced detection technology that allows the detector to distinguish non-threatening deceptive phenomena ─ such as cigarette smoke, from actual fire hazards, while optimizing detection for the area it is intended to detect. Model HFP-11 uses stateof-the-art microprocessor circuitry with error check, detector self-diagnostics and supervision programs. Model HFP-11 is compatible with the Siemens ─ Fire Safety field device program / test unit (Model DPU), which is a compact, portable, menu-driven accessory for electronically programming and testing detectors, easily and reliably. Model DPU eliminates the need for cumbersome, unreliable mechanical programming methods ─ such as dials or switches, and reduces installation and service costs by electronically programming and testing the detector prior to installation. Model HFP-11 is compatible with FS-250 and Fire Finder XLS-series control panels.
Specifications:
The Siemens Model HFP-11 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 smoke chamber is designed to manage light dissipation and extraneous reflections from dust particles or other non-smoke, airborne contaminants in such a way as to maintain stable, consistent detector operation. When smoke enters the detector chamber, light emitted from the IRLED is scattered by the smoke particles, and is received by the photodiode. Model HFP-11 also utilizes a modern, accurate and shockresistant thermistor to sense temperature changes. The ‘on-board’ FirePrintTM technology allows the detector to first gather smoke and thermal data, and then analyze this information in the detector’s ‘neural network.’ By comparing data received with the common characteristics of fires or fire fingerprints, Model HFP-11 can compare these ‘fire prints’ to those of deceptive phenomena that cause other detectors to false alarm.
All Siemens, Pyrotronics, Cerberus and Faraday detectors are tested with one of our programmers.
We verify devices are new and have never been altered or programmed
