LRA Series Compatibility Notice

The LRA series of products were upgraded in 2021.  In order to accept the necessary software changes, the control board needed to be changed as well.  

Although we do our best ensure upgraded versions of the products are compatible with older versions, sometimes it is unavoidable.  This is the case with the newest upgrade to the LRA series of products.

This is only relevant if you are purchasing a new LRA products as a replacement or add-on to a system you purchased from 1800doorbell.com PRIOR to 3/01/2021.  First time purchases on or before 3/010/2021 should no be affected.
