First of all thats to all of you who replied to my initial question about replacing the triac in lamp modules. We live in a rental house. As I have expanded the number of BSR's used I have discovered areas of the house that the controllers have trouble getting messages through to modules. Are there some obvious things to look for to get BSR throughout the house? Thanks again, George Rachor Jr. george@flight.hf.intel.com

Place a .1 MFD 1000V capacitor across the 240V line in the house like this: L1 Neutral L2 | | | | | | | <--- 120V. --> | <- 120V. --> | | | | <----- 240V. ---------------> | | | | | | | | | O-----------------------| |-----O | | | | | | | 0.1MFD | 1000VDC You can do this without disturbing the wiring by puting the the capacitor into a 240V plug and pluging it into a 240V outlet in your home. If you are experienced in working with live home wiring, use your voltmeter to locate 240V in one of the wall boxes and connect the capacitor there. The bathroom wall swith may be a good place to look if it also contains a receptical. The capacitor will allow the BSR control signals to pass to the other line, so that the whole house may be controled. It works for me.

This is available for anonymous UUCP transfer.

Most (all??) homes in the US are 220 volt mains with each branch being the 110 (117?) volt service. I had similar problems and solved them with a low value (very low value) capacitor (around .01 mf) across the 220 main (not the ground connection) don't do this with the power on (ie. do it after the main breaker, pull the fuses or breaker physically out if you can easily) and still act as if the circuit were live. (Many urban legends exist about false paths for the power when it should have been off. Try not to become a legend in your own time ...) /Tjp -Power to the people.
