General Safety Information
This document should be used by experienced personnel as a guide to the installation of the Armstrong SteamEye® monitoring
System. Selection or installation of equipment should always be accompanied by qualified technical assistance. You are encouraged
to contact Armstrong International, Inc. or its local sales representative for additional information.
Product Information
Tracking and monitoring systems allows for ongoing troubleshooting and optimization. It also allows you to know exactly where
your savings are – and how to find more. Introducing SteamEye®, Armstrong’s best practice system to constantly monitor and
instantly report your steam system’s condition for optimum energy system management and savings.
Section 1 Introduction
The SteamEye® system is designed to monitor and detect instant failure of steam traps and other steam equipment in realtime.
Using a patented Armstrong International technology, SteamEye® transmitters continuously monitor the steam equipment.
Once a failure is detected, the transmitter wirelessly sends the current operating condition of the steam trap, or other steam
equipment, to a gateway (wireless receiver). SteamEye® can also be integrated into your existing Building Automation
System (BAS) or Digital Control System (DCS) using Modbus or BACnet™ communication protocols.
In applications where the transmitter has line of sight to the gateway, the range is approximately 1500 feet. In facilities
where the signal must travel through walls, floors and other obstructions the range is 300 to 500 feet. If the receiver is out
of the range of a transmitter, wireless repeaters can be placed to “repeat” the signal back to the gateway. A radio frequency
signal strength survey is recommended to determine if repeaters are needed, where they will be located and how many will
be required.
SteamEye® can be linked to SteamStar® for real time steam loss and CO2 emissions information. SteamStar® will calculate
and quantify accumulated steam and dollar losses until action is taken. SteamStar® can also send alerts immediately when
a failure occurs, helping reduce cost and/or catastrophic damages due to steam trap failure. Advanced reporting tools
such as Benchmarking, Trending and Work Orders are also available. All of this will help prioritize busy work schedules in
today’s “do more with less” workplace and ultimately help you achieve energy efficiency and reliability goals.
The gateway is connected to your company’s network where the information can be viewed through any computer on
campus.
SteamStar®:
The SteamEye® Gateway M has the
capability to integrate into Armstrong’s
web-hosted steam trap management
program called SteamStar®. SteamStar®
allows users to calculate losses in real
time and create reports that can be shared
among colleagues. See Figure 1.1 for
potential set up options.

Section 2 SteamEye® Gateway
The Armstrong SteamEye® Gateway M is a receiver and data collection center for the SteamEye® system. The
Gateway runs on a Linux based LightTPD SSL web server and is capable of collecting data from up to 2000
SteamEye® transmitters. The Gateway can be installed on a LAN where data can be accessed through the built-in
webserver and/or the information can be integrated into a control system via the built-in Modbus table.

Section 3 SteamEye® Repeater (RP4000)
RP4000 high-power repeaters receive, decode, amplify and retransmit signals from SteamEye® transmitters. The RP4000
expands the range for any SteamEye® 4000 series transmitters, and can be used to amplify signals from other RP4000’s.
The RP4000 can be used to expand the SteamEye® system to scale from small sites to complete campuses consisting of
several buildings.
Section 3.1 Operating Information
The RP4000 Repeater is designed to operate without any need for interaction. Once the Repeater is powered it will receive
and send signals from all series 4000 Armstrong SteamEye® devices automatically.

Section 3.2 Installation Information
Prior to installation of the RP4000 SteamEye® Repeater an RF survey should have been performed to identify Repeater
installation locations. Install the RP4000 in the locations specified by the RF Survey. For maximum performance, mount the
RP4000 in an area removed from metal (metal objects such as duct work and wire mesh will reduce RF range). All installation
locations should be dry and maintain a temperature between 32°F - 140°F (0°C - 60°C). If installing in an outside location or
location where water splash maybe present, install the RP4000 in a non-metallic enclosure. See installation example, Figure 3.6
Section 3.2.1 RP4000 Power Cable Installation
The RP4000 is supplied with a transformer allowing it to be powered from any standard 120 VAC outlet.
120 VAC power is required.
1. Remove Cover – Remove RP4000 cover by inserting
a flat screwdriver in the seam of the front and back
cover at the housing release tabs and gently pry
down. Repeat this step at all retainer marks.
2. Cut Power Cable – Cut the necessary length of cable
to run from the repeater location to the power source.
Note: Wire should be two-conductor 20 AWG (or larger)
stranded-tinned copper with PVC insulation rated to
300 volts at 80 °F (26 °C). Wire length should not
exceed 328 ft (100 Meters).
Figure 3.3 – Removing Cover
3. Install Power Cable – Terminate the cable on the transformer connection screws and on the RP4000 power and ground
connections. Note: the RP4000 uses 14 VAC and there are no concerns with polarity for the wire termination locations.

4. Connect Battery Power – The RP4000 is shipped with a fully charged backup battery. Connect the battery before
re-installing the cover.
5. Reinstall the cover.

Section 3.2.2 RP4000 Mounting Installation Example
The RP4000 can be mounted to a non-metallic panel or wall using the 4 provided screws (see figure 3.2 for Anchor locations).
Please note that metallic enclosures will significantly impede on the signal transmission and should not be used for SteamEye®
repeaters.

Probe Installation
Warning:
Vaults can be dangerous and entrance to them
need to be performed by qualified personnel.
Use caution when handling the
probe, not to strike or put force on
the end of the probe. This could
cause damage to the ceramic core.
1. Remove Plug from the bottom of the Armstrong
probe connection steam trap
2. Confirm the probe is cut for the trap (this is done
by looking at the trap model on the transmitter

Transmitter Installation
There are many ways the transmitter can be installed. If the transmitter is being installed in a room or an enclosure, simply
mount the transmitter to a wall or back plate in the enclosure.
Note: All enclosures must be non-metallic material.
Another popular method to install the transmitter is in an at grade enclosure.
When placing the transmitter in an at grade enclosure it should be placed such that water will not pool around or submerge
the transmitter. Additionally water flowing directly over the transmitter (i.e. rain water runoff) should be avoided.
Place the transmitter no more than 2 feet below grade to promote maximum wireless transmission distance. The enclosure
must be constructed of non-metallic materials.
Note: Install the device so that Hazards do not interfere with or damage the transmitter. Examples of physical damage
include, but are not limited to: blowing steam or condensate directly onto the transmitter, installation in pathways where
transmitter could be struck by personnel or vehicles, etc.

Pressure Switch Wiring and Installation
For modulating steam applications pressure switches are used to verify when there is pressure to the application. This is
important as in modulating applications if there is not a pressure switch the trap would show cold when steam is not present.
The pressure switch keeps the transmitter from showing a cold trap that is not in use.
Important
Pressure Switch to be installed in
the line where the pressure is the
same as at in the trap. If it is installed
before block valves the pressure
reading will not be accurate.
Normally
Closed
(Brown Wire)
Closed when

1. Connect the supplied wire
to the pressure switch
2. Connect the connector of
the pressure switch wire
to the transmitter
3. Install the battery in the
transmitter
