Trip Wire Alarm Device
Fith Ops is the original inventor of the perimeter trip alarm. We pioneered the look, feel, and design, making us the definitive source. Any devices with our exact appearance are counterfeit products. We are the original company operating in Idaho.
We prioritize quality above all else. Our trip alarms undergo rigorous testing on the toughest primers, ensuring they work flawlessly with any type of blank. Our high-quality springs don't retain a memory, even after years of use—something you can't say about counterfeit versions.
Our trip alarms are fully off-grid, functioning as a sound alarm system. Use them to keep intruders or dangerous animals away from your home, garden, campsite, or any other area without relying on Wi-Fi or power.
Compact and portable, these alarms fit easily in the palm of your hand. Perfect for camping, hiking, hunting, or any outdoor activity where space is limited.
They work with non-lethal 12G blanks but also accommodate 209 primers, .22s, or 308 blanks using corresponding adapters. For areas where blanks are not allowed, we offer a digital adapter as an alternative.
Do not use live ammo. This device is designed to work with non-lethal blanks only. Keep it away from flammable objects. Always mount it low to the ground and point it downward. If used in rain or snow, lubricate the spring with gun oil or another waterproof substance to prevent rust.
