Auxiliary Beacon

The Pathfinder™ Auxiliary Beacon is a device used to mark way-points inside a structure. Operating on the Auxiliary (YELLOW) frequency, this low-cost device allows any firefighter equipped with a Tracker to rapidly locate internal points or rally points, including fire hose nozzles, emergency air tanks, search rope bags, or even the RIT team (when deployed). Since ultrasound signals are reflected by walls, these Beacons work even if they are located around a corner or are hidden beyond obstacles, such as furniture or debris. When turned ON, Auxiliary Beacons transmit a continuous ultrasound signal while flashing ultra-bright red AND white LED strobes. There is an additional high-volume, sweeping audible alarm that can be muted by the firefighter.

Rather than creating a single Beacon for ALL exits and "bread-crumb" trails, Summit believes it is important to distinguish between the actual exits and internal points. A firefighter needing to evacuate immediately cannot take the risk of accidentally going farther in thinking s/he is "exiting". Imagine, however, the situation where you find a trapped civilian, but cannot rescue them without extra tools. Marking the location of the civilian will allow you to return rapidly, thereby saving precious time. The Auxiliary Beacon is designed for the situations where internal marking is necessary, but cannot interfere with identification of Exits.

Auxiliary Beacons operate on a separate ultrasound frequency than Firefighter Beacons and Exit Beacons. Since Radio Frequency (RF) is not being used, there is no need for a temporary "10 second standby" to prevent the interference issues experienced by other locating systems. A Pathfinder Tracker automatically distinguishes between Beacons, making "standbys" unnecessary.

  • Standard magnet pre-installed.
  • Operator's manual
Standard Features
  • "Fire-and-Forget" Operation
    Easy to use, simple ON/OFF operation. No temporary "10 second standby" required.
  • Dual Ultrasound transmitters
    Used by Pathfinder™ Trackers™ for locating the closest way-point.
  • High intensity, audible alarm
    Beacon emmits an intermittent sweeping tone. Alarm can be muted depending on department preference.
  • Ultra-bright LED "strobes"
    8 White and 6 Red LEDs assist with locating a way-point in low or high smoke conditions.
  • Interchangeable mounting methods
    Flexible design allows department to customize deployment methods. Three standard 8-32 machine screw inserts allow firefighters to "customize" their Auxiliary Beacons with different mounting methods. The Auxiliary Beacon ships standard with a magnet pre-installed. Additional integrated strap loops in the grills allow attachment using 1" webbing or cable ties.
Optional Features
  • Nomex strap
    Optional strap can be fitted through grill slots to allow Auxiliary Beacon to be quickly attached to door handles, ladders, bannisters, or other non-magnetic objects.
