FAAST XT Intelligent Aspirating Smoke Detector - Discontinued product

Product Overview

The FAAST XT Intelligent Aspirating Smoke Detector (9251BPI) combines Dual Vision (blue LED and infrared laser) optical smoke detection with advanced detection algorithms, a wide-area sampling system, and intelligent fire alarm panel connectivity using an analogue addressable loop.

The detector incorporates an air sampling system that continuously draws air from the controlled environment into the detector chamber through a sampling pipe. The three-stage filtering and particle rejection system ensures high sensitivity to smoke with excellent immunity to nuisance particles. The particle separator ensures that heavy particles bypass the detection chamber, extending filter life and preventing detection chamber contamination. An easily replaceable filter protects the chamber from other smaller particles. The shape of the detection chamber is also designed to resist the build-up of nuisance particles. The Dual Vision sensing system employs advanced software to combine the signals from two separate light sensors for maximum smoke sensitivity while rejecting signals from nuisance particles. FAAST XT 9251BPI can accurately detect incipient fire conditions before a fire actually starts.


  • Analogue addressable loop connectivity
  • Protects up to 2650 m² in standard coverage applications
  • High sensitivity for extremely early smoke detection
  • Five alarm levels: Alert, Action 1, Action 2, Fire 1 and Fire 2
  • Two operating modes (Day / Night / Weekend and Acclimate™) for application flexibility
    - Day / Night / Weekend mode enables pre-set thresholds based on routine changes in the environment’s usage
    - In Acclimate™ mode the detector automatically adjusts thresholds to current environmental conditions
  • Dual flow detection including ultrasonic and electronic sensing for pipe and chamber airflow measurement
  • Configurable 3-speed fan allows for maximum coverage area or minimum current consumption
  • Easy configuration via USB or Ethernet 
  • Ethernet interface enables remote monitoring, configuration, web server and e-mail
  • LCD display provides interactive access to detailed information and user control functions
  • Configurable air flow fault thresholds and verification period
  • Unique air flow pendulum graph verifies pipe network functionality
  • Particulate graph displays subtle environmental changes for early indication of problems
