Hello: I successfully added a 5804BDV key to my LYNXR-EN system however it does not work more than a few feet away from the main unit. The manual says the 5800 transmitter/receiver is not necessary with the key. Could I have the wrong house code? How to I know for sure what my house code is. I set my auxuliary keypads to 10 and they work fine! Any suggestions? Keith

I've had a DSC Power 832 PC 5010 since 1997 and except changing the 124/16.5VAC transformer, it's been no problem till now. While away, I lost power. The transformer was open so I changed it to a new one and it still had now power. It has power at the main board and the fuse is ok. I suspect it may be the board itself. Perhaps it was fried during a power surge. I noticed on the board lower left corner that something black appears to have burnt and dripped down on the board. Don't know if that's the problem but perhaps it is. I'm thinking about changing the main board by switching the wires as they are presently attached to the new board. That's easy. However, will I need to re-program the system. It is not monitored and only a perimeter alarm system so I suspect it will be easier. Any advice will be appreciated. Also, and suggestions where to by the main board at a reasonable price. Thanks Dan Palm Harbor, FL (where we dodged Hurricane Wilma)
