RE: X10 Question

["White, Peter" <peter.white@xxxxxxxxxxxxx>]

What alarm is it?   I've not been able to find any alarm that supports
X10,
apart from a Prosys (currently installed, and it's bloody awful to
configure) and a wireless one whose name escapes me, but it was something
to
do with BT.  We're now ripping out the alarm and replacing it with
something
a little more standard, and just having very basic X10 via relays and
powerflash modules.  As I've got the wires I'd rather use them rather than
going wireless.

Jonathan,

The LD11's (+ 99% of all modules available in the UK) do *not* support
status response. This means that it is impossible for the alarm panel to
simply ask the modules if the light is currently on or off. In your
particular case I don't think it matters because the Alarm panel will
not be toggling the light like the light switches do, it will be issuing
an explicit X10 command "Light ON". This means if the light is
currently
off it will turn on but if already on it will remain on i.e. ignore the
command

In fact if you use an LD11 (which supports extended codes) and your
alarm panel supports extended X10 commands, then you could actually
issue a "Direct To 100%" command which would then mean that if
the light
was already on but dimmed it would brighten to 100% instead of remaining
dimmed.

Thanks for you replies on this. If I use something like the LD11 from
Lets
Automate, as Marcus suggested, and wired as Kevin said with the switches
in
parallel. I see that that pushing any momentary switch will toggle the
state
of the lights.

As I want the alarm to switch on the lights if an event is triggered, is
there a way to leave the lights on if they are already? Or is that
really
down to the level of intelligence in the alarm to check the status of
the
lights? If it is just acting as another switch then it would just toggle
from the current state and turn the lights off if they were on. Not the
idea I had in mind, I like to see where I'm running when I'm in blind
panic
:-).

Cheers
Jonathan
