The FSH Z Bracket to suit FSS1 High Security Door Monitoring Sensor (Part No. is typically FSS1-Z45) is a specialized mounting accessory for the FSH FSS1 series of door sensors, which are widely used in government and high-security installations (often SCEC SL4 rated).
The FSS1 sensor works by detecting a unique “magnetic footprint” from a magnetic array plate, making the alignment between the sensor and the plate highly critical.
