The ePIRTM Statement

ePIRTM is a revolutionary technology used for passive infrared (PIR) based motion detection.

ePIRTM is a technology that has significantly better reliability & performance than (high end current) Digital PIR detectors.

• Provides a dramatic improvement in both sensitivity and stability (false alarm & pet immunity).

• Meets or exceeds all applicable standards (present and proposed).

• Enables additional features without additional cost.White Light ImmunityAuto LEDReal time Diagnostics (self test) and more…

Traditional PIR Detectors

Traditional PIR’s are a commodity sold largely on price

• Differentiation from competitors is difficult

Designs are mature in nature

• Little room for improvements

Inherent limitations remain• High component count (low MTBF)

• Bulky electrolytic capacitors required

• Time consuming to assemble and test

• Band-Aids applied to overcome design pitfalls

What makes ePIRTM possible?

New MCU product families with advanced capabilities have allowed a revised look at the overall PIR detector design

Unique software techniques have been developed that overcome previous limitations

This “fresh” look has produced a revolutionary step in PIR detector technology called the ePIRTM with Sigma-Delta Technology

ePIRTM – AUTOLED Feature

The unique method of enabling Walk Test• LED jumper now ON and AUTO (instead of OFF)• LED = ON works the same way (LED always active)• LED = AUTO controls the LED automatically

LED is normally off until action takenLED (for walk test) is enabled by shining light on detectorEliminates removal of the detector cover for walk testing

Guarantees LED will be disabled for normal operationAUTOLED function can be customized as required
