Replacing 6270 keypad
I am trying to replace my 6270 touchscreen keypad in my alarm system. The old keypad would not light up all the time and therefore periodically I could not use it. Bought a new unit - 6270 (identicle to old unit). Hooked up then 4 wires to the correct locations and all the keypad does is blink on and off. Cannot get this to work. Any help??? Thank you.

When you say the old one would not light up, what does that mean? The screen was blank or the back light wasn't coming on? Next what does the screen look like when it blinks on and off? What all powered devices do you have on the system? Such as motion detectors, smoke detectors, wireless receiver, hard wired expansion modules, anything that draws power. What about keypads how many and what kind? Have you checked the programming for the AUI to make sure it is right? I believe it comes turned on from the factory and is set at address 1. Make sure the 6270 is addressed properly, this is done when you power it up. If the programming is correct and you have a bunch of auxillary device drawing from the panels auxillary output it could be a power issue. The 6270 is a power hog, check your mA draw of the panels auxillary power output with all devices that take power connected.

just finished installing 6270...
I don't have a specific answer to your question but having just finished installing two of them, I can tell you the problems I saw.
1) make sure the power being delivered to its terminals is at least 12V (likely 13.5V). I had an issue where a jumper fell of the power supply and was only delivering 6V.
2) With 2 6270s in the system, the first time they are powered up, they will both be asking for their ECP address. Therefore, it is best if you disconnect the power to 1 and bring up the other, enter its address, from a 6170 keypad, make sure that address is enabled (*189) and then wait for the 6270 to gets its updates from the panel. Then disconnect that 6270 unit and re-connect the other 6270, giving it a different ECP address. Once both units have their addresses programmed, they both can be turned on.
Hope this helps.

6270 replacement problem
The new one - blinks on with nothing seen on screen and then blinks off - this is repeated over and over until I disconnect it. There are two other 6270 keypads in the system and the remainder of the system works. I just don't know how to get this replacement to work. I am not sure what the "power up" is or how do do that - any help appreciated.

I think you have a power issue and that the 6270 you took down may still be in working order. Check the mA of your aux. power as stated previously. You only are alotted 600mA on the aux. power.

Most versions of the Vista panels that use the 6270 only allow 2 of them (the most recent ones allow 4), Even with the most current versions, 3 of these keypads, plus the rest of the system load are going to be pushing the panel power supply to it's limit.
Even if you have the power available, the new keypad needs to be set to the same addressing as the one you removed. Read through the installation instructions. This isn't a simple device swap.

6270 keypad
The main board has a WA 3001 4.1 (Honeywell) - does this support three 6270 touchscreen and one standard keypad? Is power a problem? Can it be arranged or "rigged"?

The system has to have processor version 3.0 or better, and the touch screens have to be version 1.0.9 or 1.1.175 (for the Symphony models).
If it will let you enter more than 2 addresses, then your model is high enough. The touch screen devices are power hungry. You can get an add on power supply like the ELK 624 (http://www.elkproducts.com/products/elk-p624.htm) and power the keypads from that instead of the aux power output from the system. You just need to tie the power supply output ground to the aux power ground. It may or may not need it's own transformer; if you have a 40va or better, the power supply card can probably safely share with the power supply card.
The card will give you another full 1 amp power capacity.
