I think you'll need the bp27-50cm but if the fan blades are the same diameter you could possibly get away with the 70 cm bp-28.

You will be far better off doing a fresh install rather than an upgrade. Definitely worth the price difference.

One of the specific requirements for the upgrade was that I had a SAT ready unit. To b sure u can inquire at a major installer. I went to Best Buy.

No it will not. You need the B1809913S or a direct replacement for that board number.

You'll have to look in your users manual. That's how I knew what replacement to buy. Sorry.

A friend just made the same upgrade and the answer for him was no. The connectors are different. Since the new unit comes with its transponder, no need to worry about it.

I am not familiar with nb672. I bought it to replace the old one for that unit.

It can be replaced as it fits into the board like RAM. If the antenna will work with your replacement card is another question. I beleive the stock unit is a two wire setup.

I do not know. I used it to replace the obsolete # 1276. I determined that it was a good substitute by visiting the Kidde website

Not according to their compatibility chart...check site. THR138 is what you need.

I am notan expert but I believe that this is just the upgraded, digital version of the 15-73502. It should work just fine. It will only take 15 min. to change.

contact 'computer upgrade king' and inquire. I think they can make it with whatever you want in it.
