GTRM 100 Ground Test Remote Monitor From Ventev

Stop Copper Theft and Monitor Your Site's Grounding System

Ventev GTRM 100
Ventev's GTRM 100 is a small, easy-to-install monitoring device that connects to your site's grounding system creating its own monitoring circuit. When the circuit is interrupted, an alert message will notify the NOC through an Ethernet or contact closure connection. The GTRM 100 was specifically designed to be a smart, simple, economical, and reliable monitoring solution to increase the site manager's awareness of potential catastrophic failures. Copper theft remains an operational threat and the GTRM 100 is an elegant solution to an expensive problem.

The GTRM 100 has been designed for a quick and easy installation. There a many variables for installation as every site is slightly different but the principles of the installation remains the same.

The first step is determine what you would like your installation to accomplish. Would you like an installation to deter copper theft or would you like an installation to catch copper thieves in the act and prevent them from hitting other sites.

There are multiple ways to accomplish either of these scenarios and the GTRM 100 is versatile enough to perform either task flawlessly.No matter which installation step you choose, the principles of installing the GTRM are the same for every site.

GTRM 100 - Installation
Step 1 - Mount the GTRM 100 in a suitable location either inside the shelter or inside the site cabinet.

The GTRM 100's housing contains mounting flanges allowing you to mount the GTRM securely with standard fasteners.

The ideal location for mounting would be close to a power source and provide easy access to outside grounding bars or cabling that you wish to monitor.

GTRM 100 Ground Connections
Step 2 - Choose the Connection Points to Monitor and run the wiring

The GTRM 100 can simultaneously monitor up to 5 different connection points. These points are generally outside ground bars, however any point that allows for a wiring connection that is connected to the entire site ground can be monitored by the GTRM 100.

Running the wiring to the connection points is determined by how you want the installation to appear to the would-be copper thief.

In general, most of our customers prefer to run a #6 ground wire to each of the site and tower ground bars. This makes for a clean installation and the GTRM connection wires match those of the site and tower ground leads that are already connected to the ground bars using the same lugs.

GTRM 100 Terminal Block
The GTRM connection terminals use a 18 AWG wiring and the common connections to the ground bars at most sites are 6 AWG wiring. A terminal block is used in the installation to provide a smoother transition between the two different gauges of wiring.

The terminal block also provides a location for testing the installation to verify all connection points and that the GTRM is functioning properly.

The final wiring connections are to the GTRM 100 channel terminal blocks. These connections use a screw down terminal on the outside of the GTRM housing.

Step 3 - Connect Power to the GTRM 100

The GTRM 100 comes in both DC and AC powered versions. The DC powered version allows you to connect directly to your site's DC power supply and take advantage of the onsite battery backup to ensure that the GTRM does not lose power in the event that the copper thieves cut power to the site.

The optional AC powered GTRM 100 uses an AC adapter to connects directly into any standard AC outlet to provide a quick and easy power up inside a shelter or cabinet.

Step 4 - Make Final Connections to GTRM

Depending on the type of alarm notifications you want to receive will determine what else needs to be connected to the GTRM.

Dry Contact Alarms - A connection must be made between the dry contact terminals to your alarm monitoring terminal block.

Email and SNMP Alerts - If you are going to utilize the email notification, then a Network (Ethernet) cable must be connected to the GTRM and the network settings will need to be updated for connection to your network.

If you plan on using SNMP to send alert messages over the network, again the Ethernet connection to the network is required and a Network Adminstrator will be required to configure the SNMP trap receiver to accept messages from the GTRM 100.

Step 5 - Final Testing

Once all connections have been made, perform some final testing by removing a couple of the wires at the terminal block to generate alarms on the GTRM. Make sure you are generating alarms through the dry contacts and confirm that everything is wired properly.

If using email or SNMP alerts, confirm that you have recieved the email message and SNMP trap messages.

Copper Theft Detection

The GTRM 100 provides copper theft detection by utilizing a proprietary technology to monitor crucial points throughout the site grounding system.

Copper Theft Detection
During copper theft, it is these key areas that are targeted. The GTRM 100 provides instant feedback and generates an alarm the moment something is tampered with. You will know instantly if someone is stealing your copper. The GTRM 100's realtime monitoring of these keypoints is what makes it the most effective solution for all of your copper theft problems.

Each critical point of your grounding system is monitored independantly to allow the GTRM 100 to activate alarms on any or all of the critical points where events have occurred.

Generally these channel leads are connected directly to the site ground bars but the leads can be connected to other crucial elements of your site that copper thieves may target such as your HVAC system.

The GTRM 100 can be installed in a variety of applications and configurations providing an endless possiblity of options for what it can monitor and detect.

Real-time Alarms

TheGTRM 100 provides realtime alarm notifications in three different ways:

  1. Email Alert Notification
  2. SNMP Network Message
  3. Dry Contact Closures

Alarms will be generated at the very instant an event is detected and the notification will sent in the manner in which you choose. All alarm notifications can be activated and used at the same time so you can send an email alert message to the site technician or manager and at the same time a network message will be sent via SNMP to the Network Operations Center and the dry contact closures can be activated to tie into your existing site alarm system.

With its multiple alarm notification methods, the GTRM provides maximum flexibility for a variety of installation types.

Alarm Notification Types

Email Alert - The GTRM Ethernet port provides access to any IP based Network. The GTRM allows for IP configuration and will transmit alarm alerts via email through any network mail server.

SNMP - The GTRM is configurable to be used with any network SNMP server. SNMP trap messages are sent across the network and captured by the SNMP network monitoring server providing the Operations personnel with realtime alert notifications the moment the GTRM goes into alarm.

Dry Contacts - Can be configured to be set to "normally open" or "normally closed," the dry contact terminals provide endless possibilities when wiring up the GTRM to provide alarm notifications. Many users wire the contacts directly to their existing site alarm system or even to their third-party monitored "burglar alarm system.

You can even use contact closures to activate "instant on" video cameras, strobe lights or audible alarms to deter the copper thieves from any further damage to equipment or copper cabling.

Ground Sensor

Through the use of an optional sensor connected to the GTRM, the health of the entire site grounding system can be monitored.

If the Ground Sensor on the GTRM detects a fault in the grounding system, the unit will go into alarm. The alarm notification again can be sent via Email, SNMP, or through the Dry Contacts.

This provides an additional piece of mind that not only is the GTRM actively monitoring your critical grounding points against copper theft, but it is also providing feedback that the integrity of the site ground itself has not been compromised.
