STI 6254 Mini Theft Stopper without Door Clip

Protect cabinet-mounted fire extinguishers and critical equipment from theft and misuse with the Safety Technology International STI-6254 Mini Theft Stopper. This compact door/cabinet alarm provides audible theft deterrence and immediate on-site notification — emitting a 105 dB horn when a protected door is opened. Powered by a single 9V battery and housed in tough, UV-resistant ABS (3.5" x 3.5" x 1"), the STI-6254 installs easily next to a door or inside a cabinet and uses a wired reed switch and matching magnet for reliable contact monitoring.

Designed for facilities-focused security, the Mini Theft Stopper preserves accessibility for authorized personnel via a service deactivation pin while preventing unauthorized removal or tampering. Its bright red housing improves visibility for maintenance and first responders and complements broader surveillance and monitoring programs by providing localized, audible alerts that speed response times. Ideal for schools, hospitals, industrial facilities and commercial properties, the STI-6254 is a straightforward, cost-effective addition to asset protection and loss prevention strategies.
