Replaced a MSU 480 that had stopped working due to failure of transformer. New device works like it should. Good manual.

Installed MSU480 for a remotely located sensor in ceiling, and installed in cabinetry with AV components. This works perfect. Not any issues, except maybe need the reading glasses inserting the wires in the terminal strip. This has been very reliable. I would highly recommend this product!
