Step 3: Mount the sounder on the wall
Note
The sounder is protected against unauthorised opening and wall tampering contact
via the housing tamper switch and the wall tamper switch. The tamper information is
transmitted to the alarm panel.
Note
A moulded piece in the recess of the backplate (Point 4 Image 3) serves as an anti-
removal wall contact. This moulded piece is fixed to the wall with a screw. If this is not
done, tamper detection for the wall is deactivated.
Danger
If the moulded part is not mounted to the wall, the sounder will lose its certification for
security level 2.
The sounder was designed so that changes are detected if they last at least 400 ms
(EN50131-1 Chapter 8.9.1 and EN50131-3 Chapter 8.9 and Annex B).
Breaking and entering, intrusion and tampering signals must last at least 400 ms.

•
Place the sounder on the wall and align it vertically. Use the base plate as a drilling
template and mark the four fixing points.
•
Drill the holes in the wall to fit the diameter of the screw anchors. Insert the screw anchors
supplied, in the holes.
•
Insert the supplied
screws through the sounder’s fixing holes. Turn the screws in the screw
anchors. Do not tighten the screws yet. Vertically align the sounder once more. Now tighten
the screws.
