Flush Mounting – Plasterboard

Tip

If this is your first plasterboard installation, check the



function of the intercom side clamps. Loosen and then

re-tighten the clamp screw to see how it turns

automatically and starts moving forwards in its slot.

Remember to return the clamp into the original position

after the check!

Caution

Check the plasterboard wall and room interior pressure



values (caused, e.g., by overpressure ventilation). If the

difference between the values is too great, separate the

intercom using, for example, the mounting box enclosed

and seal the cable passage to avoid loudspeaker

damage.

1. Cut a hole using the template enclosed (165 x 95 mm).

2. Unscrew the front panel from the door intercom.

3. Connect the cables in the hole to the terminals or RJ

connector as described in the Electric Connection

subsection.

4. You can use the cable tie for connection as shown on

previous page.

Mounting completion – after electric installation!

5. Insert the intercom in the hole keeping it in the vertical

position.

6. Loosen the four clamp screws one after another and then

retighten them slowly. They will turn aside automatically and

start moving forwards in their slots. You need about 10

turns to tighten the clamps completely. You can perfect the

vertical position before final tightening of the screws.

7. We do not recommend you to insert the button tags now.

8. Replace the stainless steel front panel fixing it with the

stainless steel screws you unscrewed in step 2.

Use the wall (surface) mounting box, part No. 9153003, and follow the instructions

enclosed.
