Caution!
DC24V voltage is in dry contact input interface of DCS and NRI, therefore, only connect to the
power or relay to output. Do not connect to external voltage signal, and confirm the port types
when connecting to the third-party system. If the output of third party system is voltage signal,
please use relay to switch the signal.
Connecting the Noise Detector (Optional)
If environmental noise detection is required, the AVC port should be used to connect the noise
detector to the system.
Only the X-ND100 is compatible with the X-DCS3000. Shielded twisted pair cables are used to
supply power as well as transfer the noise data signal. The steps are as follows:
1. Open the rear cover of noise detector, and set the module address 1~5 per binary system.
Switch to ON position as shown below:
