Viking offers better chimes than RDL. Talk to Fred.
I considered that RDL FP-CH8 for a Nuvo integration, but I'm going with the Viking SLP-1 or SLP-4 instead.
Nuvo white paper offers the install instructions for both the RDL and SLP-1. SLP-4 offers the option of customized .wav files played as the chime.
Here is a link to the factory-loaded SLP-4 chimes, including dogs barking and door knock. ;)
[Link: vikingelectronics.com]IIRC, there's about a $100 difference between the SLP-1 and the SLP-4; RDL FP-CH8 was about the price of the SLP-1.
Beat me to it, totally agree here.
