2.2 Mechanical Installation

Mounting Types Overview

Refer to the table below for a list of mounting types and necessary components. You can assemble multiple units in all the mounting types.

 

Flush mounting – classic bricks

  • incl. hollow bricks, thermally insulated walls, etc.

What you need for mounting:

  • a properly cut hole as instructed in the box package
  • plaster, mounting glue, mounting foam or mortar as necessary
  • 2N Access Unit
  • flush mounting box and frame
    • 1 module: box Part No. 9155014, frame part No. 9155011
    • 2 modules: box Part No. 9155015, frame part No. 9155012




Flush mounting – plasterboard

What you need for mounting:

  • a properly cut hole as instructed in the box package
  • 2N Access Unit
  • flush mounting box and frame
    • 1 module: box Part No. 9155014, frame part No. 9155011
    • 2 modules: box Part No. 9155015, frame part No. 9155012


Wall (surface) mounting

  • (concrete and steel structures, entry barrier columns, interiors, etc.)

What you need for mounting:

  • 2N Access Unit
  • a proper frame
  • 1 module: frame Part No. 9155021
  • 2 modules: frame Part No. 9155022

For uneven surfaces use a backplate for the required count of modules, Part Nos. 91550619155062.


Caution

  • Before starting the mechanical installation on a selected place, make sure carefully that the preparations connected with it (drilling, wall cutting) cannot damage the electrical, gas, water and other existing wires and pipes.
  • The warranty does not apply to the product defects and failures arisen as a result of improper mounting (in contradiction herewith). The manufacturer is neither liable for damage caused by theft within an area that is accessible after the attached electric lock is switched on. The product is not designed as a burglar protection device except when used in combination with a standard lock, which has the security function.
  • When the proper mounting instructions are not met, water might get in and destroy the electronics. It is because the intercom circuits are under continuous voltage and water infiltration causes an electro-chemical reaction. The manufacturer’s warranty shall be void for products damaged in this way!

General Mounting Principles

Tip

  • Select flush mounting where possible to make your product elegant looking, more vandal resistant and more secure.
  • You are advised to buy the flush mounting box in advance and commission a building company to do the masonry for you, for example. The mounting box also helps you put your intercom exactly in the vertical position.


Caution

  • Make sure that the diameter of the dowel holes is accurate to avoid falling out of the dowels! Use the mounting glue to secure the dowels if necessary.
  • Make sure that the depth of the dowel holes is accurate!

  • Do not use low-quality dowels to avoid falling out of the dowels of the wall!

  • Having removed the front panel, make sure that no dirt gets inside the product (especially onto the sealing surface).

  • Never turn an assembly of 2N Access Unit devices after mounting. Make sure that the flush mounting boxes have been installed accurately.
  • Check the plasterboard wall and room interior pressure values. If the difference between the values is too great (as a result, e.g., of overpressure ventilation), separate the intercom using, for example, the mounting box enclosed and seal the cable passage.
  • Surface mounting may cause problems on places exposed to potential vandalism (such as public garages, etc.). In this case, use steel anchoring elements instead of the dowels and screws included in the delivery.
  • The wall mounting surface must be flat with the maximum inequality of 0.5 mm (e.g. prefabricated boards, glass, cut stone, etc.). If the surface is uneven, use flush mounting and a backplate, Part Nos. 91550619155062, or equalise the wall surface.


Risk of personal injury

  • Eliminate the risk of personal injury! Wall mounting is not recommended for narrow passages or places where people’s attention is distracted by something else. The manufacturer shall not be liable for injuries in such cases!
