INSTALLATION

Note: Always try to attach the sensor to a vibration free surface.

Acoustic Tile Mounting
Install the Threaded Insert, flange side, into the hole on the
back of the sensor and turn clockwise until it locks.

Keyhole Mounting
Positioning of keyhole mounting screws is important so that
the transducer pairs point in the desired direction.
1. Use the template below to mark the location of

mounting screws.

2. Install the provided screws—leaving approximately

3mm (1/8") space from the bottom of the screw head
to the ceiling (see diagram).

3. Place the sensor’s mounting keyholes over screw

heads and rotate sensor clockwise until secured.
