The Survivair Pathfinder, utilizing Pulse ultrasound technology, consists of an omni-directional transmitter (the Beacon) and a narrowly focused receiver (the Tracker). On a Survivair Panther®, there are two Beacons built into the SCBA—one attached to the COMPASS™ integrated PASS device on the user’s front, and one attached to the back side of the backpack (either with or without an activated DoublePASS™ remote alarm module for COMPASS). The Beacon is the target sensed by the Tracker which indicates the direction and location of the downed firefighter wearing the Panther SCBA. If the firefighter is motionless and the Survivair COMPASS goes into alarm mode, the Panther Beacons are activated (they can also be manually activated).
By having two Beacons—one on the front and one on the back—an ultrasonic signal will have a clear transmission path, no matter which way a firefighter has fallen. Readouts on the Tracker show the strength of the firefighter’s signal, indicating whether the firefighter is near or far, behind an obstruction, or accessible along a particular path, regardless of the smoke concentration. By scanning an area with the Tracker and then by moving in the direction of the strongest signal, the firefighter can be located.

Benefits |
- Beacon transmitter mounted on COMPASS in front of firefighter and on back of backpack
|
- Allows clear transmission path no matter how the firefighter falls
|
- Beacon activated by COMPASS
|
- Allows automatic activation once firefighter is motionless
|
- Beacon allows manual activation
|
- Firefighter who is trapped but conscious may generate signal for rescue
|
- Beacon incorporates flashing LED signals
|
- Four initial flashes of red LED alert user that Survivair Pathfinder is activated; repeated flashes of green LED alert user that Pathfinder is in sensing mode, looking for a lack-of-motion signal from COMPASS; repeated flashes of red LED when COMPASS is in full alarm mode indicate Survivair Pathfinder is transmitting an ultrasonic signal
