RE: Re: Beam Breaks - worthwhile?

["Kevin Hawkins" <lists@xxxxxxx>]

Alcinda,



You can buy a small  (inexpensive) X10 device that will send X10
ONOFF commands based on a couple of  contact terminals that it provides -
doing it this way you would connect the beam sensor direct to this device.
I
can't just remember what it's called but it's often used to interface alarm
outputs to X10. I can find out for you though if you want with a quick
trawl
of one of the usual sites.   This will only give you ONOFF synchronised to
the beam break - you still won't be able to do the fancier stuff ( dim or
delays) until you have a more capable controller. Eg HV

This is undoubtedly a stupid question that will demonstrate nothing
but my ignorance, but here goes...

Your beam breakers work with HomeVision, which I can't afford
(yet...).  I'm still using the CM12U.  Is there any way, do you think,
of adapting the beam breakers to work with a CM12U - via RF say.  Or
would I simply be reintroducing the time delay that's there with the
PIR sensors (I'm not sure at which point the delay occurs, or whether
it's just accumulative).

I currently use two PIRs to detect activity and switch on the lights -
one to cover the bedrooms for the midnight toilet run that becomes
more frequent as one gets older, and one to cover the front door
should I suddenly discover a social life and come home after lights
out!  However the delay has caused more than one anxious pause at the
top of the stairs to the bathroom (multi-levelled house) whilst I wait
for the lights...
