Do any fire sounds interfere with the operation of the Pathfinder system?

0

No. Fires can produce a significant amount of acoustic noise. Much of this noise is in the audio range, and only a small amount reaches the ultrasonic frequencies used in the Pathfinder system. Since a Beacon in alarm mode transmits a continuous ultrasonic signal at a very specific frequency, the Tracker looks for this continuous signal and ignores all signals that are not at the correct frequency. As a result, a fire may occasionally give a small ping of ultrasound which can cause the LED bar graph to momentarily turn on one or two LEDs but will not give a continuous reading on the bar graph.
