Optex Fmx St Dst Picture

Product Details

The FMX-DST is a high performance indoor PIR motion detector for high-end residential and light commercial applications. The FMX series features Plug-in End of Line Unit (PEU) for easier and quicker installation. The FMX-DST model provides extra stability in environment with strong sunlight.

FMX has 78 dense zones to cover the whole detection area. At any spot within the detection area more than 4 (quad) zones are utlised to verify if an alarm should be generated or not. Additionally, the CORE processor used in the FMX series enables to improve the Quad Zone Logic by providing digital quantification of infrared energy. This enhances the accuracy level to differentiate between human or small animals.

Certification: Grade 2 EN50131-2-2

Double conductive filter Advanced Temperature Compensation Logic
For advanced false alarm prevention, the FMX-DST features Double Conductive Shielding, which allows infrared energy to pass through to the element, but blocks out RFI (Radio Frequency Interference) and light sources since it features a special conductive filter that covers the element window.
The FMX-DST automatically increases the detector's sensitivity under high temperature conditions, especially where the background temperature ranges from 35-37°C(63 - 67°F), close to that of the human body.
