INSTALLATION GUIDE FOR THE

DC Voltage Detector

ENVIROMUX-DCVD-xxx

INTRODUCTION

The NTI ENVIROMUX-DCVD-xxx is a DC voltage detection contact sensor which, when connected to an ENVIROMUX-SEMS-16
or ENVIROMUX-MINI, closes when the monitored voltage is in the 26-36VDC range. The contacts will remain closed unless the
monitored voltage drops below 24VDC, at which point the contact will open. A 2-wire sensor cable (6 foot cable included), is used
to connect to an ENVIROMUX, which can be configured to send alerts based on the presence or lack of DC voltage.

Models available:

ENVIROMUX-DCVD-24V – For use with ENVIROMUX-SEMS-16
ENVIROMUX-DCVD-24VM – For use with ENVIROMUX-MINI (SEE NOTE BELOW)

Note: The ENVIROMUX-DCVD-24VM is only compatible with ENVIROMUX-MINI units made on or after 11/1/07 (see label
on the bottom of your ENVIROMUX-MINI). If your ENVIROMUX-MINI was made prior to 11/1/07, please order model
ENVIROMUX-DCVD-24V. Failure to use the correct voltage detector will result in inaccurate alert reports.

Features:

¾ Monitors the presence of 26-36VDC
¾ 2-position screw-terminal connection
¾ Supports 2-wire sensor cable up to 1000 ft

INSTALLATION

Place the ENVIROMUX-DCVD-xxx where it can be plugged into an DC power source (26-36VDC). Connect a 2-wire cable
between the terminals on the ENIVROMUX-DCVD-xxx and the “CONTACTS” terminals on the ENVIROMUX-MINI, or the
“DIGITAL IN” terminals on the ENVIROMUX-SEMS-16

When using 2-wire cables longer than 100 ft, be careful to route cables away from AC wiring, lighting sources, electric motors, or

other electrical devices.

The wire connection terminal blocks are easily removed from the ENVIROMUX-DCVD-xxx, ENVIROMUX-MINI, and

ENVIROMUX-SEMS-16 for more convenient wire termination.

In the event that the ground terminal is unavailable, the negative terminal ( ) has the same potential and can be substituted.
