Extra Sensor Motion Detector.

If you have a SY-007-Plus, it is possible to expand the set to 5 Sensors. There is one number on the back of the Sensor. Please purchase an additional sensor. then check whether you do not already have the sensor with the same number.
Example you have 1 motion detector and sensor No1 and No2. you could then add each sensor (this does not have to be in order), but it is important that you do not have 2 the same numbers.

Ps. The bottom of a sensor or motion detector also states whether you are in possession of an SY-007 or SY-007-Plus

• PLEASE When purchasing, indicate whether you need No3, No4 or No5.
• Each motion sensor contains 3 AAA batteries (not included)
