Hello guys would someone kindly assist where possible. So I have this project where I need to install perimeter lights with a motion sensor for each. In addition to this a 240v siren is required. My question is how can I achieve triggering the siren regardless of which direction the motion is detected on these perimeter lights?

3poles each having led light and a motion sensor. Siren is on 1 pole but must be activated by any of the 3 sensors on the 3 poles. Please help and thank you in advance.
