The DR40 features a built-in, Normally Open (NO) relay that can handle up to 30 VAC/DC, with a maximum current of 1A. To ensure compatibility, check the transformer specifications to confirm the power requirements.

Rhombus recommends trusted brands like NICOR and Newhouse Hardware. We have experience using the NICOR Wired Single Gang Chime and the Newhouse CHM3D.

Note: Installation may require the expertise of an electrician or licensed installer. We recommend you consult the appropriate federal, state, and local authorities for any relevant regulations at the time of installation.
