* This protocol provides support for some chinese Alarm "gadgets" (Motion detectors and door/window contacts)
|
|
* Note that these modules are reported as X10 switches to the Home Automation software so that they work correctly

|
* PIR Motion detection unit:
|
|
* PCB contains 2 chips: biss0001 & ev1527
|
|
* BISS0001 = Micro Power PIR Motion Detector IC
|
|
* EV1527 = OTP Encoder, max. of 20 bits providing up to 1 million codes.
