Combining quad zone PIR technology and unique microwave detection

DX series are the result of Optex's advanced research with PIR and Microwave technology. Also the design of this product offers easy, trouble-free installation in a compact and attractive housing. These models have features necessary to accommodate virtually and installation.


Microwave Technology
(Patent Pending "Area Shaping Technology")

Optex has creaed a breakthrough in Microwave Detection. This DX series reduce one of the biggest weak points of microwave detection, that is the penetration of walls and unwanted detection of movement outside the coverage area. In addition, the detection area has uniform sensitivity which minimises false activation's caused by spot movement in the detectino area, i.e.small anmals. The DX series is new dimensions in microwave techno,llogy.

Passive Infrared Technology
(Patented Quad Zone Logic)

By utilising Optex Advanced Optical Technology,the DX-40/60 create evetly distributed sensitibity throughout the detection area. Accurate focus creates even sensitivity and high resistance to spot temperature changes. Other detectors may have inconsistent detection creating hot spots (false alarm can occur) and dead spots (no detection). In addition,the New Spherical Lens contributes to a superior aesthetic appearance which end users will appreciate.

Detection Area Size Configuration
"Microwave Area Shaping Technology" and " Quad Zone Logic"

The Microwave Area can be easily shaped to fit the desired area and have even sensitivity. In addition, Quad Zone Logic in the PIR provides high tolerance to spot temperature changes and movements caused by small animals, heating vents, moving curtains and vibrations caused by big machinery. Fail-Safe Technology - Automatic Trouble Monitoring

I like the DX-40 for doing a large area. The MW section was better over the Visonics Duo/K9-80. The creep zone seemed pretty good over some other detectors also.

Price seems pretty good too as the Visonic was much more in cost.

As another person noted, you will hear a small clicking noise when it triggers. But it is so low that you need to be pretty close to it to hear it.

I found that if there is a large heat source turning on, that the DX-40 PIR will trigger, even though its MW section did not. I noted the Visonic did not trigger in the same location. I have a propane open blue flame heater (9-30K BTUs). The solution was to move the DX-40 so that it did not face the heater.
