GTRM 100 Installation Guide
Overview
The GTRM 100 was designed to provide an easy and convenient way to remotely monitor ground cabling and components at site locations prone to copper theft.
The GTRM 100 contains everything you need to activate alarms and automatically send alert messages via email or SNMP. Providing you with instant feedback the moment a copper line is cut or a ground bar has been removed that is being monitored by one of the 5 ground monitoring channels on the GTRM.
The procedures in this guide outline the steps you should follow to correctly install and operate the GTRM 100.
**DANGER**Although the GTRM 100 Monitors grounding components caution should be taken during
installation. Live power wires may be in close proximity to the installation location of ground monitor leads or the main unit. Do Not touch or remove any live AC lines during the installation of the GTRM. Serious Injury or Death could occur from electrocution.
GTRM Standard Components
The GTRM is a self-contained DC powered unit an optional AC power adapter is available if your installation requires it. Please verify that you have received everything with your order.

GTRM Installation
Because the GTRM can be used in a variety of applications there are many variations on exactly how the GTRM can be installed and connected to ground lines. Please use the steps below as a guideline for installing the GTRM. Proper testing should be done after installation to ensure you receive the desired level of alarming and alert messages.

Installation Steps
Step 1: Mounting the GTRM
Mount the GTRM in a suitable location inside the shelter or cabinet.
The GTRM mounts easily to any flat surface. The mounting flanges can be used to mount to wall or board, two-sided tape or Velcro can also be used to secure the GTRM.
The mounting location should be in close proximity to the exit point of the ground wires that you wish to monitor.
Step 2: Choose the Connection points to monitor and then Run the Wiring.
Typical locations to monitor are the main shelter ground bar and the tower ground bars. Leads should be run from each channel terminal on the GTRM to each point you wish to monitor.
Connecting the Channel Monitor Wires: Connections to the tower ground bars and the shelter ground bars typically use #6 wires. You can connect to these locations with smaller gauge wiring but it is common practice to use the #6 wiring and lugs to connect the GTRM to these monitor points in order to “mask” or “hide” the installation and make all the connection look the same.
8
Using a Terminal Block: The #6 wiring will then be reduced to 18 AWG wire inside the cabinet or shelter by using a standard terminal block. The 18AWG will then connect to the GTRM channel block.
Connecting the Comm Terminal: The Common wire from the GTRM is connected to the main ground bar inside the shelter or cabinet. The common wire must be connected or the GTRM will not function properly.
Step 3: Connect Power to the GTRM
The GTRM comes in both AC and DC versions. The DC version is preferred as it allows you to connect the GTRM directly to your site power supply which takes advantage of battery backup and provides continuous monitoring in the event of a power outage or if the copper thieves cut the AC power to the site.
DC powered GTRM will wire directly into your site DC power supply or terminal block.
AC powered GTRM comes with an adapter that plugs into any standard 120VAC outlet or power strip.

Step 4: Make Final Connections To GTRM
Choose your method of alarming and make Ethernet and Dry Contact connections as necessary.
Ethernet Connection will require you to configure IP Network Settings and Email parameters.
SNMP trap messages and network configurations will be necessary if using GTRM SNMP functionality for alarming. Coordination with your network administrator will be necessary to configure SNMP alarming on the GTRM.
Dry Contacts can be set to normally Open or normally Closed and can be access via the browser interface.
Step 5: GTRM Power up and Final Installation Testing
Once the GTRM is powered verify functionality and alarm notifications. If using the Web Browser to configure the GTRM, it may be necessary to power cycle the GTRM in order for it to update save the changes.
The terminal block (if installed) can be used to simulate copper cuts and test your installation to verify that the GTRM goes into alarm and that everything is configured properly.
By removing connections at the terminal block you should see the GTRM go into alarm and you can verify:
10
If using email alerts, confirm receipt of alarm notification email when GTRM goes into alarm. This will verify your network and email configurations are correct.
Verify SNMP setup and receipt of correct SNMP messages when GTRM goes into Alarm
Confirm dry contact configuration and wiring is setup correctly when GTRM goes into alarm. If using the dry contacts to wire into an existing alarm monitoring system, verify that the alarm company is seeing the alarm notification.
GTRM Configuration
The GTRM monitors and senses Ground wires in two different manners. The first is through a ground sensor Toroid to detect the presence of an active ground and the second uses pulse monitoring through up to five different channels to detect connectivity of ground lines to a ground plate.
The Toroid Ground Sensor
The Ground sensor uses a clip-on toroid to detect low level currents on the ground wire that generate a magnetic field inside the toroid. The Toroid converts this magnetic field to electrical current and passes it on to the GTRM. If the magnetic field is no longer present, (ground is lost), the current to the GTRM i s interrupted causing the GTRM to go into alarm.
When the Toroid Sensor is in alarm, the indication will be displayed through Alarm 2 on the GTRM.
To Install the Toroid Ground Sensor
1. Locate the main ground feed wire that you wish to monitor.
2. Open the clip sensor and place the sensor around the wire.
3. Close the clip sensor around the ground wire.
4. Connect the Ground Sensor wire to the RJ11 jack on the GTRM
5. Enable the Sensor by checking the appropriate box in the Options Menu of the Web interface.
Connecting the GTRM Channel Terminals
The GTRM can monitor up to 5 different channel lead locations. The channel terminal blocks will accept 18 – 24 AWG wire. It is recommended that you use smaller wire to connect directly to the GTRM channel terminal blocks and then use a split-bolt style connector to attach the channel wire lead to a larger wire that will then connect to your ground plate.
1. Using 16 or 18 AWG wire, determine the correct length needed to connect to copper ground wire or to attach directly to the ground plate.
2. Strip off approx. ¼” of coating to expose copper wire and insert into channel terminal. Screw down terminal to secure wire. Repeat for the desired number of channels you wish to monitor.
Note: you do not need to wire all terminals. You can use any of the terminals or all of the terminals. You can activate and deactivate each channel by using the push buttons on top of the GTRM or by accessing the configuration settings through a web browser.
Activating GTRM Channel Monitoring
The GTRM monitors up to 5 separate channels. Each channel operates independently and can be activated or deactivated by either the push buttons on top of the unit or through the configuration menu.
