X-ND100 (Digital Noise Detector) is used to detect ambient noise, automatically calculate the noise
SPL, and transmit the SPL data to X-DCS3000. It is an important component to fulfill the function of
automatic volume control. While broadcasting, the sound is mixed with ambient noise. In order to
measure the noise SPL accurately, X-ND100 measures broadcast signal from speaker lines, compar­ing with the one from microphone to get the actual noise data.

Connect to X-DCS3000 by a pair of cables, through which fulfill
communication and power supply.
Max. 5 noise detectors for each channel.
Currently collect broadcast signal and noise signal.
Max. transmission distance is 1000m.
Flush-mounting in ceiling.
Fire-proof ABS shell.
Ideal for indoor installation.

1. Installation

Builders can conveniently install the noise

detector into a hole with diameter of 160mm in

the ceiling, and fix it with the spring clamps on

both sides of shell. Thickness of ceiling is

5~25mm.

2. Wiring

There are two terminals inside the noise detec-

tor. One is used to connect the control

line for communication and power supply, and

another is used to connect speaker line. The

polarity of wires shall conform to the marks

beside the terminals. Generally, 0.75mm2

twisted wires are recommended. If the distance

from noise detector to controller is up to 1000m,

please use 1mm2 twisted wires.

1.Dig a hole with diameter of 160mm in
the ceiling;

2. Put the cables through the hole of
back shell, and then connect them to the
terminals inside the noise detector. The
polarity of wires shall conform to the
marks beside the terminals.

3. Align the slot of the back shell to the
right place, and fix it.

4. Make both sides of springs toward to the ceiling hole,
and push the noise detector into the hole. The spring then
automatically lock the noise detector to the ceiling.
