I had a Comfort II system installed in my new home end of 2011 which provides security as well as a few other things such as interfacing with KNX.
[size=The system was installed with 2 KP04s and I added an additional ]KP03 [size=myself a few years back which worked great.][size= ][size=I now plan on adding the final KP04A but am wondering, is there any technical limitation to doing this? I know the system supports up to 8 keypads but is there a possible limitation in terms of current to power the additional KP04A? ]
The latest Ultra comfort firmware supports up to 15 keypadsEach should have its own unique IDYou should not need anothr power supply, although If you have a SLave that should also act an an additoonal power siupply (with backup attery added)
