Just another thought about an alternative to that device above:=0D

What if you need to connect a couple motion detectors and / or window reed=

switches etc etc? At =8850 per connection, it gets expensive=85=0D

I=92ve had the same problem and used a standard DIY motion detector

Since this devices needs 3-5V triggering it, (240V directly coming from

motion detector would blow it up!) I used a Relay that gets triggered by

SM10 will by the way require something similar: it either accepts =91low=0D
voltage=92, ie. 6-18V or a dry closure, which is basically connecting the
t=

input pins together.=0D
A standard motion  detector will mostly switch a lamp, therefore has 240V=

output. You would also need to put a relay in between.=0D
Here is where you can get one: (scroll down till you find one for 240V) =0D
