2.8Flush-mounted Contribution equipment

DCN’s broad range of flush mounted units form the building blocks for creating individual system contribution units for use in custom built solutions.The flush-mounted units are intended for use in fixed installations, where portability is not required.The units can be neatly installed in to either table- tops or seat armrests.The range of flush-mounted units available, provides all the functions and facilities offered by the table-top contribution units. For example a delegate unit can be created by combining a Multi-purpose connection unit LBB 3540/15 or Dual Audio Interface Unit LBB 3535/00. These units being the main components when creating flush-mounted solutions in combination with

the following units:

All flush-mounted units are available in standard sizes of 40 x 120 mm (1.57 x 4.72 in) with the exception of the flush-mounted loudspeaker unit LBB 3538/00 which has a dimension of 80 x 120

mm(3.14 x 4.72 in) and the Delegate/chairman voting control panel LBB 3542/00 which has a dimension of 80 x 240 mm (3.14 x 9.44 in).The dimensions of the flush-mounted units allow units to be neatly installed and positioned along side each other in either a portrait or landscape type configuration.

Mounting

All DCN’s flush-mounted units include a ‘click-to-fit’ mechanism, enabling units to be secured into cut- outs on table-tops or the armrest of seats in a landscape or portrait type format.

Two methods are used to mount the flush-mounted units. Method 1 is used when mounting units into a metal surface and method 2, used when mounting units into a wooden surface.

Method 1 (mounting into a metal surface)

The ‘click-to-fit’ mechanism available on all flush mounting unit is used to secure the units into cut- outs on table-tops or the armrests of seats etc. Additional screws are needed when mounting LBB 3537/xx Control Panel with microphone.The recommended method when installing the units, is to install them into a 2 mm (0.07 in) thick metal panel.The metal panel is used as the platform for securing the units.The panel needs to be cut-out according to the units template.

NOTE: Table top mounting is also possible for certain units with the Table-top housing LBB 3527/00. Refer to Chapter 2.24.

Method 2 (mounting into a wooden surface)

Units are secured by screws using the holes available on each unit. All units include drill guide holes located under the front cover of each flush-mounted unit.The guide holes are used for guidance when drilling the units screw holes.
