Trip-Line Radio Alert™

The new Trip-Line Radio Alert™ is a trip-line activated early warning long-range intrusion detector alarm which alerts you via an audible indication while the intruder remains unaware of the activation. It’s simple to operate, and utilizes FRS radios to send you the intrusion alert. It has a range of about one mile!

The field-deployed transmitter unit is housed in a compact O-ring sealed weather-resistant case, which the trip-line easily plugs into. Our proprietary electronic modifications to the transmitting radio enable it to draw zero battery power until it’s activated, allowing it to remain in the standby mode indefinitely.

The transmitter radio is powered by three AAA alkaline batteries. The receiver radio is powered by three rechargeable AAA batteries. Includes transmitting radio in case, receiver radio, Trip Plug, all 6 batteries, USB charging cord, one 75 ft. spool of Ballistic Trip Line™,  and mounting hardware. Transmitter case size: 6.7” x 4.5” x 1.7”. Made in USA.

By agreeing to these Terms, you hereby certify that you are eligible to receive locksmithing devices through the mail pursuant to 39 U.S.C. Section 3002a (a) because one or more of the following terms describe either you or your business:

1. a lock manufacturer or distributor.

2. a bona fide locksmith*.

3. a bona fide repossessor.

4. a motor vehicle manufacturer or dealer.

5. sworn commissioned law enforcement officer.

These Terms were made to induce vendor to send one or more locksmithing devices as defined in 39 U.S.C. Section 3002a (b) to you through the mail and it is expressly understood that vendor will be relying upon your agreeing to these Terms contained herein in filling the undersigned’s order.

*The statute does not define the term “locksmith”. Webster’s Third New International Dictionary defines a locksmith as follows: “a worker who makes or repairs locks.” It is the position of vendor that the term “locksmith” may be deemed to include an individual or organization, a reasonable and substantial portion of whose job description includes the activities normally associated with a locksmith as that term is defined, for example, but not by way of limitation, the security or maintenance department of a hospital, tow truck operator, and so forth.
