NTI ENVIROMUX SENSOR INSTALLATION
11
RJ45 Sensor Cable
The CAT5 connection cable between the ENVIROMUX and connected external sensors is terminated with RJ45 connectors and
must be wired according to the EIA/TIA 568 B industry standard. Wiring is as per the table and drawing below. The sensors
that connect to “RJ45 Sensor” ports (E-xD) or the “Temperature/Humidity” ports (E-MINI-LXO) are all designed to use cables
wired to this standard.

Liquid Detection False Alert Fix
Problem:
Receiving false alert messages from installed ENVIROMUX Liquid Detection sensor E-LDx-y or
E-LD-LCx-y.
Cause:
Sensor is in environment with significant electrical noise and is picking up this noise and conducting it back
to the ENVIROMUX Environment Monitoring System providing a false signal of closure.
Solution:
Install a .1uf capacitor (available from NTI) between the two “Digital In” terminals the Liquid Detection
sensor is connected to as shown below. (E-MINI-LXO used for example, but this applies to any ENVIROMUX
Environment Monitoring System.)
Note: This is to be applied only to installations of Liquid Detection Sensors. Applications with other sensors
may cause the ENVIROMUX to malfunction.
