Re: X10 - PIRs - MS13 and MS14

[vincentb <vincentb.37muua@xxxxxxxxxxxxxxxxxxxxxxxxxx>]

There is one 'hacky' way you could do it.  Open up an MS13 and cut the
light-dependent-resistor off.  Then connect those two wires to your
other motion sensor's contacts.  When that motion sensor triggers, it
will short out the MS13's light-sensor.  Programme the MS13 so that its
motion doesn't work but it's sunset detection does.  That way it only
sends an X10 signal when the other motion sensor triggers.

but remember, the sunset-detection is one unit code above the motion's
unit code.  so if you programme the MS13 to B4, for example, it will
actually transmit B5 when the sunset-detection wires (that are
connected to your other motion sensor) are shorted.

Or you could wire up your motion sensor to a device that injects an X10
signal directly in the mains when its contacts are shorted.  Have a look
at the AIX12 product, made by a company called Xanura.  It works on A10
(which is compatible with X10, but with 10 times stronger signals, to
alleviate inteferences).

Here's an example:

That is, if you have the ability to connect such a device to your
mains, where the motion sensor is located.
