The FSS1 Series Door Position Sensor (DPS) was designed as a state-of-the-art monitoring solution for high-security applications in government and military installations. It uses seven magnetic sensors to detect the unique magnetic footprint of the magnets on the opposing faceplate.
FSS1 learns its three-dimensional environment using one sensor to detect the distance of the magnetic faceplate in relation to the device, while the other six sensors are used to determine the polarity, size, strength and position of the magnets on the unique faceplate. This three-dimensional data is registered into the device. Any interruption, change, or tampering with the device cover will trigger a response at the door and/or through the network as a silent or audible alarm.
