Hard ceiling installation

Surface mounting

Completed installation

Parts required for installation

1. Surface mount adapter

2. Screw (M4 × 50 mm) × 4

3. Tile bridge A × 2

4. Tile bridge B × 2

5. Seismic cable

6. Zip tie

7. Installation template

1. Drill holes in the ceiling for attaching the microphone.

   • Use the enclosed installation template to drill mounting holes according to the specified dimensions.

   • Installation may not be possible in some areas depending on the placement of the ceiling frame. Check the internal structure of the ceiling before choosing an installation location.

   

2. Attach tile bridges A and tile bridges B to the inside of the ceiling.

   • Align the screw holes of tile bridges A and B with the holes drilled into the ceiling to attach.

   • Securely attach tile bridges A and B to the ceiling frame so that a sufficient load can be supported.
     

   • If the placement of the ceiling frame makes it difficult to ensure a secure installation, use nuts and bolts to attach tile bridges A securely to the ceiling frame mounting holes.
     Applicable bolt size for mounting holes of tile bridges A: W3/8 or M10

   

3. Attach the surface mount adapter using the screws (M4 × 50 mm).

   • The stamping on the surface mount adapter indicates the orientation of the microphone.

   

   1. Stamping indicating microphone orientation

4. Run the cables inside the ceiling.

   

5. Attach the seismic cable to the ceiling frame.

   • Securely attach the seismic cable to a strong point on the ceiling frame.

   • Slide the unlock pins to release the lock for adjusting the wire.

   

   1. Unlock pins

   	Attach the seismic cable so that there is as little slack as possible. Using the seismic cable with a large amount of slack could increase the impact exerted were the microphone to be dropped and may result in an accident, injury, or damage to the microphone. If the impact from a fall is applied to the seismic cable, replace the cable with a new one.

6. Pass the cables and the seismic cable through the hole in the surface mount adapter.

   

7. Attach the seismic cable to the microphone using the screw for seismic cable.

   

   1. Screw for seismic cable

8. Connect the wired cables to the microphone.

   • See Connection procedure for details on connecting the cables.

9. Pass the zip tie through the microphone and the surface mount adapter to attach the microphone to the surface mount adapter.

   • Make sure the tab on the surface mount adapter is securely hooked on the microphone before pushing up the other side of the microphone to attach it.

   

   1. Zip tie
   2. Tab on surface mount adapter

10. Tighten the zip tie to secure.

    

Flush mounting

Completed installation

Parts required for installation

1. Surface mount adapter

2. Flush mount adapter

3. Flush mount cover

4. Screw (M4 × 10 mm) × 12

5. Hole cover

6. Nut × 4

7. Snap bushing × 2

8. Tile bridge A × 2

9. Tile bridge B × 2

10. Tile bridge C × 4

11. Seismic cable

12. Safety belt

13. Installation template

1. Cut out a square hole in the ceiling for attaching the microphone.

   • Use the enclosed installation template to cut out a mounting hole according to the specified dimensions.

   • Installation may not be possible in some areas depending on the placement of the ceiling frame. Check the internal structure of the ceiling before choosing an installation location.

   • Max. ceiling thickness for installation: 25 mm

   

2. Attach tile bridges A and tile bridges B to the inside of the ceiling using the screws (M4 × 10 mm).
   Adjust tile bridges C to the height of the ceiling frame and attach using the screws (M4 × 10 mm).

   • Attach tile bridges A and B to the ceiling by aligning with the square hole cut into the ceiling.

   • Securely attach tile bridges A, B, and C to the ceiling frame so that a sufficient load can be supported.

   • If the placement of the ceiling frame makes it difficult to ensure a secure installation, use nuts and bolts to attach tile bridges A securely to the ceiling frame mounting holes.
     Applicable bolt size for mounting holes of tile bridges A: W3/8 or M10

   

3. Attach the surface mount adapter to the flush mount adapter using the screws (M4 × 10 mm).

   • Align the arrows on both the flush mount adapter and the stamping on surface mount adapter when attaching.

   

4. Attach the hole cover with the nuts.
   

   • If using both holes, skip this step and proceed to the next step.

   

5. Attach the snap bushings.

   • Press your hand on the snap bushing from above to insert it into the wiring hole.

   • When wiring a large number of cables, attach both snap bushings without using the hole cover.

   

6. Run the cables inside the ceiling.

   

7. Attach the seismic cable to the ceiling frame.

   • Securely attach the seismic cable to a strong point on the ceiling frame.

   • Slide the unlock pins to release the lock for adjusting the wire.

   

   1. Unlock pins

   	Attach the seismic cable so that there is as little slack as possible. Using the seismic cable with a large amount of slack could increase the impact exerted were the microphone to be dropped and may result in an accident, injury, or damage to the microphone. If the impact from a fall is applied to the seismic cable, replace the cable with a new one.

8. Pass the cable and the seismic cable through the snap bushing hole in the flush mount adapter, insert the flush mount adapter into the square hole cut into the ceiling, and secure with screws to attach the flush mount adapter.

   • The stamping on the surface mount adapter indicates the orientation of the microphone.

   • Securely tighten the mounting screws when attaching the flush mount adapter.

10. Connect the wired cables to the microphone.

    • See Connection procedure for details on connecting the cables.

11. Attach the microphone to the surface mount adapter.

    • Make sure the tab on the surface mount adapter is securely hooked on the microphone before pushing up the other side of the microphone to attach it.

    

    1. Tab on surface mount adapter

12. Attach the safety belt by hooking it onto the flush mount adapter and flush mount cover.

    • Ensure the safety belt is attached in the correct orientation.
