First Alert FA250KP keypad

Anyone happen to know the pin out for the First Alert FA250KP keypad? I have one but do not have any installation instructions for it. I need to make my own connector to hook to it and can not find what pins on it are +, -, Data in, Data out....
Thank you for your time.

Without having a connector in my hands, I believe that it's green(Dout), black(-), red(+), yellow(Din). From left to right looking at the back of the keypad. You may have to experiment, or look at an already mounted keypad. All of the Ademco family hardware uses the same connector.

THANK YOU! You have no idea how many places I have asked that question and not gotten any reply to. I am a little leery to blindly apply 12 volts to the wrong pins on that keypad. The panel is a FA120C which is the same as an Ademco 4110XM so I bet your right. The FA215 pad on it has nice screw terminals and they are marked on the PCB...I wish all would mark the boards.
This one has the connector on the right (looking from the rear) and it is orientated top to bottom. It looks like the connector key grooves are on the near side (closest to me when viewed from the rear) of the connector...So your left to right "should" be top to bottom...or turn the darn thing sideways and it would be left to right?

Pin 1 Data IN (Green)
Pin 2 Negative power (Black)
Pin 3 Positive power (Red)
Pin 4 NO CONNECTION
Pin 5 Data Out (Yellow)

Thanks for your help on this!

I figured that the key would be off somehow. I forget what that fifth connection is used for on some keypads/panels. I think that it may be for some type of voice connection. Most of the Ademco's I deal with are
ADT legacies, and tend to be fairly simple hardware-wise (it's a college town).

After some looking I did find a panel that had the same keypad and a spare pad pigtail inside the panel. It had pin 4 key blocked and I needed to tap it out with a paper clip...I also have seen other connectors not alarm related where a key plug was glued in place and only using a heated paper clip to melt a hole into it would un-block it. I am not a fan of clipping off a pin due to a keyed connector.
Again, than you. Your correct power pins info got me going to where I only needed to find the data lines.
