How to install (Keep Door Open)

Instructions on how to lock a door in the option position:

  1. Make sure the HEAD (Triangular Top) is always in this starting position. (Fig #1)
  2. Hold the unit firmly at the back part of the HANDLE. (Fig #2)
  3. Holding the door open at a 90-degree position, insert the unit into the door jamb gap as shown. (Fig #3). The inserted HEAD will line up to go through the gap opening.
  4. Push the spring-loaded HANDLE in through the door jamb opening as far as it will go, the triangular HEAD will protrude out through the back side of the door and door frame. (Fig #4)

The door will remain open at the desired position. (Figure 8)

How to uninstall (Close Door)

Instructions on how to release the door and allow to close:

  1. Slightly push the door open (taking pressure off the HEAD), until the locking button pops up and disengages from the main shaft.

  3. After rotating the handle 90 degrees to the left, pull back on the handle until the unit comes out of the door jamb. The door is now able to be closed.

Tactical Door Jamb Assist (Operating Lights)

Tactical Door Jamb Assist (TDJA) Beacon Warning Lights

The TDJA has a special lighting feature valuable to first responders and other emergency personnel. This feature enables a person to deploy the unit in a door frame and activate the lighting system which will let others know their point of entry, and the Red, Yellow or Green lights indicate the threat or danger level present.

The TDJA comes partially charged. Upon opening the package use the included USB charging cord to fully charge the unit. Plug the charging cord into any USB outlet and plug the smaller end into the charging port located near the lens cap on the handle. A red light will appear, indicating the unit is charging. The unit will be fully charged when a Blue light is illuminated (full charging time is approximately 2 hours).

To Operate Beacon indicator Lights:

Press the button on the back of the TDJA handle for the following lighting cycles:

  • 1X - RED = Danger/ Extreme Caution
  • 2X - YELLOW = Caution / Active Scene
  • 3X - GREEN = All Clear I No Danger
  • 4X - OFF (battery will be on standby)

Additional information regarding TDJA lighting system:

  1. Battery recharge cycle time is 2 hours from fully depleted
  2. When fully charged, battery standby time is 15 hours.
  3. Low battery warning- lights transition from blinking to solid, when 15 minutes of battery life remaining.
  4. Operating temperature range = -10F to 165F

  • "Thank you for allowing my department to test and review the Tracer Line, it is a wonderful tool that will benefit the fire service tremendously."

    Bill Pepe
    Deputy Chief, Branford Fire Department
  • "The Tracer Line is a useful tool that can aid firefighters in finding their way out of smoke filled environments. The Tracer Line would be an “excellent” tool for any department – especially those who may have to search multiple apartments or office buildings."

    Steve Pegram
    Writer/Product Review, Fire Rescue Magazine
  • "Over my 31 year carrier I have tested many products used to save a victims life as well as my own. I responded to the Oklahoma City Federal Building attack and the WTC attacks of 911. In both of these cases as well as others I responded to, having a product such as the Tracer Line would have been of tremendous value."
