Hybrid door or window opening detector (reed switch) Ajax DoorProtect Fibra black

The Ajax DoorProtect Fibra Black is a miniature, wired magnetic door/window opening detector designed for the professional Ajax security system. It uses the proprietary Fibra technology for ultra-reliable, power-efficient, and long-range communication with the hub. It is equipped with a high-end reed switch that detects when a door or window is opened. Its key feature is the inclusion of an external contact that allows you to connect a third-party detector (like a roller shutter sensor or vibration sensor), effectively giving you two detection zones in one device. It comes in a sleek black casing for discreet installation on dark frames.
