Trapwire is a low-voltage wire used at hinge points where severe flexing occurs, usually in burglar alarm systems, made with tinsel conductor to withstand the repeated flexing.
Trapwire is a low-voltage wire designed for use at hinge points and other locations where severe, repeated flexing occurs, most commonly in burglar alarm and security systems. It is made with tinsel conductor, formed from thin metal ribbons wrapped around a textile core, which gives it the flexibility and resistance to fatigue needed to survive constant bending, such as at a door or window hinge. This allows trapwire to maintain a reliable circuit where ordinary wire would soon break.
Because doors, windows, and similar points flex the wire every time they move, trapwire's tinsel construction is essential to its long service in these applications. The low-voltage signal it carries suits the security circuits it serves.
In commercial and industrial security systems, trapwire connects sensors at moving points to alarm circuits. Recognizing the term helps in understanding how wire is made to endure the flexing of hinge points.
Because doors, windows, and similar points flex the wire every time they move, trapwire's tinsel construction is essential to its long service in these applications, with the low-voltage signal it carries suiting the security circuits it serves in alarm systems.
