FP-11 Siemens FirePrint Intelligent Fire Detector.

The Intelligent Fire Detector FP-11 Siemens is a highly evolved detection system that provides a very sophisticated level of fire protection, along with superior immunity to nuisance-alarms.

Direct Replacement: OP921.

Model FP-11 Siemens utilizes highly developed detection technology that allows the detector to distinguish non-threatening deceptive phenomena (i.e. − cigarette smoke) from actual fire hazards, while optimizing detection for the area of its intended zone. Model FP-11 uses state-of-the-art microprocessor circuitry with error check; detector self-diagnostics, and supervision programs.

Model FP-11 Siemens is compatible with the Siemens − Fire Safety Model FPI-32 upgrade kit or Siemens’ field-programmer / tester, Model DPU / FPI-32, which is a compact, portable, and menu-driven accessory for efficiently programming and testing detectors electronically.

The upgrade kit (Models DPU or FPI-32) eliminates the need for cumbersome, unreliable mechanical programming methods, as well as reduces installation and service costs by electronically programming and testing the detector prior to installation.

  • Multi-criteria fire detection
  • Sophisticated ‘detector intelligence’
  • Remote-sensitivity-measurement capability
  • Easily programmed to match specific hazard profiles from the fire-alarm control panel (FACP)
  • FirePrint™ technology to distinguish between deceptive phenomena and an actual fire
  • Pre-Alarm reporting based upon fire profile selected
  • Field-cleanable chamber with replaceable chamber parts
  • System-logic activation based upon any of three (3) inputs from the detector (smoke, heat or neural network)
  • Supports software-based, automatic environmental compensation
  • Backward compatible with older MXL systems
  • Optional fully programmable relay base, audible bass, and duct housing


  • DB-11 Detector Mounting Base.
  • DB-11E Detector Base (small).
  • AD2-P Air Duct Housing.
  • AD2-XHR Air Duct Housing w/ Relay.
  • ADBX-11 Audible Base.
  • DB-X11RS Relay Base.


Model FP-11 is a plug-in, two-wire, and multi-sensor detector with photoelectric and thermal inputs that are compatible with the FireFinder XLS and MXL family of FACPs. Each detector consists of a dust-resistant, field-cleanable photo chamber; a solid-state, nonmechanical thermal sensor, and microprocessor-based electronics with a low-profile plastic cover and base.
