The Addressable Door Retainer (ADR) is a game-changer for fire safety professionals and building owners alike, engineered to save time and money onsite through effortless and faster installation.
The ADR is a brand new product of its type to the UK market. Although there are many wired magnetic door holders, in the UK market there is not a loop powered, addressable door holder.
The ADR is easy to install and doesn't need additional devices like an I/O Unit, Power Supply and Mains Isolator that would normally be needed for a conventional door retainer solution.
