Using an LD11 as an appliance module ?

[Marcus Warrington <marcus.warrington@xxxxxxxxxx>]

Have just spent the Bank Holiday weekend plumbing and fitting our new
bath.. and now want to get the LED lighting wired up to the main light
switch, but don't really want to use the CLUNKY AD10 module. At the
moment I have 3 LD11's controlling the six recessed ceiling lights in 3
banks of two. What I'm proposing is to now split it so that 4 lights
(over the main floor area) are on one LD11, then the 2 lights over the
bath are on another and then to use the "spare" LD11 to drive the
LED
lighting.



The LED Lights are run from a 12v transformer that I have in a sealed
weatherproof box under the bath, the feed for this is going up to the
distribution board in the attic roof space. From here 3 lengths of T&E
run to the consumer unit housing the LD11's (in the first floor landing
cupboard). My plan is to connect this feed to the 3rd LD11 but
disconnect the local light switch control and have it only switched via
Homevision issuing an extended X10 command (on at 100%) when it detects
the lights are turned on in the bathroom. My only concern is that if by
"accident" a dim command is sent to the LD11 either by a remote
control
or a corrupted X10 packet,  would  this kill the 12v transformer or have
some dangerous effect ?



I know an AD10 is the proper way to go, but they are just too loud to be
usable...wish some one would make a quite DIN mounted version.

I've even considered using a micromodule but the problem there is that
if the (momentary) light switch is pressed for more than 1.75seconds
(i.e. local dimming control) the module treats it as a normal latching
light switch and would then switch off the LED's when the (momentary)
switch was released. Why is nothing ever simple :-)



In fact that reminds me... has anyone ever come across a momentary
switch that only briefly makes a closed contact regardless of how long
you hold the switch down ? i.e. would disable local dimming control
while still allowing on/off control of LD11's?
