Description

A robust wired normally-closed contact sensor designed for hardwired professional integration with standard alarm control panels via the NC supervised loop. Detects the tilting, lifting or forced mechanical opening of roller shutters, sectional overhead doors, skylight panels and similar closure types. Built with a durable housing suited to commercial, industrial and high-traffic environments where long-term wired reliability is preferred over wireless battery-dependent solutions. Directly compatible with virtually all alarm panels that accept a standard normally-closed dry contact input — no additional interface required.
