What I dont get is the 'Relay'
The bit where it says 'SW out'(attacked to the relay)
Im not sure what that is?
Sw out is where you would connect to alarm system or other device.
You could , for example connect to a buzzer that would sound when someone walked near the motion detector.

600r could be the coil resistance
also for the sw out, can i add a switch?

furthermore, normally there is a code for the type of relay used...
the thing i have found on ebay is
RS-12 12V DC Relay DPDT/2PDT 1A 24VDC/125VAC /2 Circuits/
