Essential Info

With double the basic performance and easy installation, the CX-702RS delivers reliable detection in large indoor areas. The wide angle setting covers an 85° wide area at 70 feet by 70 feet. Long range detection covers an area of 150 feet by 8 feet. The unit's optics are completely sealed and feature a dual structure. This unit is battery operated and features a form C alarm output.

The CX-702RS's highly accurate and reliable detection pattern will maintain its sensitivity throughout the entire detection area, even in high temperature or low contrast environments. Multi-Focus Optics create an extremely high vertical zone density, two or three times the size of conventional PIRs. These taller zones capture the entire body mass and enable detection of even the smallest temperature contrast against the temperature of the background. In addition, the vertical detection density has been improved to take into account dead zones created by furniture or partitions.


More Info

Patented Double Conductive Shielding
The Double Shielding lets infrared energy pass through, but blocks out light sources since it features a special conductive filter that covers the element window.

Sealed Optics - Complete Shielding with Dual Structure
The pyro electric element is completely sealed with the dual-structured internal molding of the housing cover, thus preventing false alarms caused by drafts and
small insects from getting inside.

Spherical Lens Design
Conventional flat lenses inevitably create sensitivity distortion problems when they are bent to fit a curved housing. OPTEX's spherically designed lens will obtain sharp detection because no bending is required.

Dual Purpose Lens
By simply rotating the spherical lens, you can select between Wide Angle and Long Range patterns. The CX-702 will instantly provide reliable and precisely accurate detection for each pattern.

Temperature Compensation Circuit
The Temperature Compensation Circuit will bring stable detection capability under high temperature conditions, where the background temperature is similar to that of the human body. It maintains a high level of false alarm protection while providing accurate detection by automatically adjusting its sensitivity according to the environmental temperature.

False Alarm Protection
  • RFI Protection - Built-in noise reduction chip blocks out RFI noise with field
    strength of 30V/m
  • Temperature Protection - No alarm in high, low and changing temperatures from
    20° C to 50° C ( 4° F to 122° F)
Disturbance-Free Tamper Switch
Completely sealed housing structure greatly eliminates disturbances to Tamper Switch.
