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.

The ENVIROMUX-DCVD-xxx can also be connected to the “RJ45 SENSORS” sockets on the ENVIROMUX-SEMS-16. When
using a CAT5 patch cable to make connection, you must first determine what wiring standard the cable has been made to. Make
connections based on the chart below.

OPERATION

The ENVIROMUX-DCVD-xxx is designed to close the circuit between the “ + “ and “ “ terminals when DC voltage is greater
than 26VDC. If the voltage drops below 24VDC, the circuit will open. The “PWR” LED on ENVIROMUX-DCVD-xxx will illuminate
when the circuit is closed.

The circuit status can be monitored by either the ENVIROMUX-SEMS-16 or the ENVIROMUX-MINI. Each ENVIROMUX can be
configured to send alert notifications when the circuit opens or closes. Configuration of the ENVIROMUX-DCVD-xxx is done on
the “Digital Input Configuration” page of the ENVIROMUX-SEMS-16 web interface and the “Dry Contact Sensor Configuration”
page of the ENVIROMUX-MINI web interface. A sample configuration page from the web interface for each product is shown
below.

Please refer to the appropriate section of the ENVIROMUX manual for additional information on the configuration pages. (See
ENVIROMUX-SEMS-16 manual pages 27-31 “External Sensor Configuration” and “Contact Sensors”, or ENVIROMUX-MINI
manual pages 17-18 “Sensor Management”. )

INSTALLATION NOTES

• It is not necessary to install an ENVIROMUX-DCVD-xxx to monitor the DC circuit which provides power to the ENVIROMUX-
SEMS-16. The ENVIROMUX-SEMS-16 has built-in power monitoring and battery backup and will send an alert in the event
of a power failure.

• In order for the ENVIROMUX-SEMS-16 to send an e-mail alert, the attached network components (routers, mail server, etc.)
must have power. If you are using the ENVIROMUX-SEMS-16 and ENVIROMUX-DCVD-xxx to monitor the DC circuit
providing power to any of these network components, be sure they will not lose power during a fault condition. (See image
below.)

DC Circuit #1

DC Circuit #2

• If your network components will lose power during the DC fault condition, use an alternate means to send alerts such as a
GSM Modem (ENVIROMUX-GSM) or Auto Voice Dialer (ENVIROMUX-AVDS). The ENVIROMUX-GSM and ENVIROMUX­AVDS are powered by the “Aux Pwr” port on the ENVIROMUX-SEMS-16. (See image below.)

DC Circuit #2

• If you are using the ENVIROMUX-DCVD-xxx to monitor the DC Circuit wIth the ENVIROMUX-MINI, be sure the
ENVIROMUX-MINI and any other necessary network equipment (router, mail server, etc.) will not lose power during the fault
condition. (See image below.)
