2N Access Unit M Surface Installation Box Spacer, 02932-001

2N Access Unit M Surface Installation Box (Spacer)

The 2N Access Unit M Surface Installation Box is a spacer that sits between the wall and a 2N Access Unit M reader, creating a cavity where the cables can be terminated. It is the answer for walls that cannot be drilled or chased, such as the concrete wall of a garage, because the reader is always surface mounted and the cabling has to go somewhere behind it. Where the wall can be cut, the matching flush installation box (02940-001) is the alternative.

Where It Fits in the Installation

The Access Unit M is a slim reader meant for door frames and walls, and 2N points out that it is always mounted on the surface of the wall. This box raises the reader slightly off the wall and gives the installer a pocket to land the Ethernet cable and the lock and sensor wiring. 2N's installation manual describes it as the surface counterpart to the flush box, which is built into the wall.

Does it work with the 2N Access Unit 2.0?

2N documents this box for the Access Unit M. Do not assume it fits the Access Unit 2.0 or other 2N readers.

Does the reader mount on the surface or in the wall?
