The LOOP (20 foot) is a sensor device that can be used indoors and outdoors. You can think of it as an electronic bike lock tha tyou can use to tie up your tools and equipment (such as backhoes, generators, ladders, etc.) If the LOOP is cut or disconnected when the tattletale alrm unit is armed, an instant alarm signal will be transmitted.

The LOOP can be placed up to 2000 feet away from the alarm unit depending on structures and objects between the it and the tattletale.

The LOOP can operate normally between 0F and 120F and is completely waterproof. The 3V lithium battery included will typically last for 1-2 years.
