Battery Statement
RF Code warrants all tags to be free from defects in materials and workmanship for a period of 1 year.
Based on the ratings and specications from the battery manufacturers, RF Code develops usage models to calculate the
life of the active RFID Tags. Like all models there are assumptions and approximations involved. The values are to be
taken as engineering estimates - not guaranteed performance.
In most asset tag deployment scenarios, RF Code tags with a 10-second beacon rate have a useful life of 5-to-7 years.
In most sensor tag deployment scenarios, RF Code tags will typically have a useful life of 3 or more years.
Exposure to extreme temperatures for all tags will shorten the battery life.

Introduction
e R151 Tethered Temperature Sensor is a battery-powered RF transmitter that monitors and reports the temperature
measured by a digital thermometer located at the end of a 6-foot plenum-rated tether cable. is design provides physical
separation between the RF transmitter and the sealed temperature sensor. is allows the tethered sensor cable to be in-
stalled in harsh environments, particularly when compared to the R150 Temperature Tag. e R151 Tethered Tempera-
ture Sensor is ideal for monitoring within freezers or other areas where condensation occurs.
is form factor is particularly well-suited for environments where the RF transmitter is mounted in open space while
the temperature sensor is installed inside RF-blocking enclosures such as a metal duct work or refrigerators. Mount-
ing is easy and exible. e temperature tether sensor cable can be routed into dicult to reach places, such as above a
suspended ceiling or inside HVAC air ducts. e RF transmitter will report its own unique ID, along with the ambient
temperature measured by the temperature sensor every 20 seconds.
RF Code’s Environmental Monitoring solution line is made up of:
• R120 Door Tag
• R130 Dry Contact Tag
• R135 Fluid Detector Tag
• R150 Rack Temperature Tag
• R151 Tethered Temperature Sensor
• R155 Humidity-Temperature Tag
• R160 Air Pressure Tag
• R170 PDU Family of Tags
• Sensor Manager Software
Features
Features of the R151 Tethered Temperature Sensor include:
• Operating temperature range from -67° F to 212° F
• Temperature reporting accuracy of +/- 2° F between 14° F and 185° F and accuracy of +/- 4° F below 14° F and
above 185° F
• e temperature sensor can be installed inside metal enclosures without aecting RF transmission range
• Removable and re-attachable temperature sensor
• Temperature sensor design suitable for use in plenum spaces
• Real-time temperature monitoring for harsh environments (e.g., higher/lower temperatures and condensation
compared to the R150 temperature tag)
• Leverages existing RF Code active RFID infrastructures

Hardware
e RF transmitter is housed in a polycarbonate case that is 3.5 in (88.9 mm) wide x 2.5 in (64.3 mm) deep x 1 in (26.2
mm) high. It can be securely mounted using the provided industrial adhesive or optionally using user-supplied screws,
fasteners or tie-wraps. e digital temperature sensor has a small footprint and is attached to a 6 ft long plenum-rated
cable. e temperature sensor tether cable is attached to the tag’s terminal connector block using a two-wire connection.
e cable is user-removable for installations that require temporary detachment for mounting. RF Code tags and sensors
are designed to ensure clear RF transmissions in high-density deployments, such as within racks and data centers. e RF
transmitter operates with a low duty cycle that translates to long battery life. e R151 temperature tag has an expected
life of a minimum of 5 years*.
RF Transmitter Operational Specications
• RF Transmitter Operational Temperature: -20° C to +70° C (-4° F to +158° F)
• RF Transmitter Storage Temperature: -40° C to +80° C (-40° F to +176° F)
• Sampling Rate: 20 seconds
• Temperature Sensor Tether Cable Operational Temperature: -55° C to +100° C (-67° F to +212° F)
• Temperature Sensor Accuracy: +/- 2° F from -10° C to +85° C (14° F to +185° F)
Power Specications
• Battery Type: ree (3) Lithium CR2032 replaceable coin cells
• Battery Life: 5 years*
* e R151 RF Transmitter can operate over the operational temperature range and withstand periods of time subjected
to the RF transmitter storage temperature limits, however the battery life is optimized at 5 years for normal use in
temperature-controlled environments between 50° F and 130° F. If the RF transmitter is subject to prolonged exposure
or use under extreme temperature conditions, this will decrease the life of the batteries. e R151 Tethered Tempera-
ture Sensor design allows the tag unit to be installed inside less extreme environments while the more durable tempera-
ture sensor tether cable is installed in areas exposed to more extreme temperatures or condensation. e RF transmitter
should be protected from condensing environments; condensation can cause the electrical circuit or mechanical con-
nections to become unreliable. Exposing the RF transmitter directly to liquids may cause the product to malfunction,
or permanently damage the circuitry, and voids the product warranty. Based on the ratings and specications from the
battery manufacturers, RF Code develops usage models to calculate the life of the active RFID Tags. Like all models,
there are assumptions and approximations involved. e stated values are engineering estimates and not guaranteed
performance. Exposing the RF transmitter to extreme temperatures will shorten the battery life. RF Code warrants all
tags to be free from defects in materials and workmanship for a period of 1 year. Featuring a low-battery alert, the tag
will continue to monitor and report temperature for at least two months following the initial low battery condition.
After that, the tag will continue to broadcast its unique ID and a low battery indication with each beacon, but will not
report temperature until the batteries are replaced.

Installation Steps
7
PN01805 REV00
Installation Steps
1. Extend the temperature sensor inside the space to be monitored (e.g. inside refrigerator, freezer or under raised
oor) and secure with the tie-wraps and tie-wrap mounting pads provided with the device.
2. Mount the RF transmitter using the provided adhesive pad or by optionally securing with screws or tie-wraps
(not provided). To mount the RF transmitter using the adhesive backing, remove the protective backing, posi-
tion the sensor tag where it is to be mounted and apply rm pressure for ten seconds.
Best read-range can be achieved by mounting the RF transmitter at least 4 ft. or more above the
ground.
3. Secure the temperature sensor using the provided tie-wraps so that movement of the cable is minimized.
Once the R151 Tethered Temperature Sensor has been properly installed, it can be congured within RF Code’s Sen-
sor Manager software where users can view tag details, use graphs and reports to analyze temperature trends, or create
alert policies to send notications. For information regarding conguration of Sensor Manager, please refer to the Sen-
sor Manager Administrator Manual and User Manual available at:
http://www.rfcode.com/Resources/Library/User-Manuals.html
Temperature Sensor Tether Cable Connection Steps
In some installation instances the temperature sensor tether cable may need to be removed. e following steps outline
the process for removing and reattaching the temperature sensor tether cable:
1. Remove the R151 RF Transmitter case top using a Philips head screwdriver to remove the four case screws and
set aside tag case top and screws.
Figure 1: R151 Remove RF transmitter Case Top

5. Determine proper position and placement for the R151 Tethered Temperature Sensor mounting. Keep in mind
that the temperature sensor tether cable will need to be reattached to the adhesive and its positioning should not
cause strain on the tag nor the tether. Remove the paper backing from the tag and press rmly for ten seconds to
mount it into place (or optionally secure by using mechanical fasteners or tie-wraps).
6. Slide the exposed cable ends back into the tether connector, paying close attention to the proper polarity. e
Red cable wire should be positioned in the left (+) terminal and the Black cable wire should be positioned in
the right (-) terminal (See image below). Tighten the terminal connector screws down to make contact with the
temperature sensor tether cable wires using a size 2 or smaller Flat head screwdriver.
Take care to avoid twisting and fraying the end of the exposed wires when tightening the terminal
connectors. Doing so can cause connection issues and cable damage.
Figure 4: R151 Temperature Sensor Tether Cable Wire Attachment
Recommended Best Practices
e RF Transmitter should be mounted four feet or more above the oor to enable the best possible read range.
RF elds of active tags are aected by large metal surfaces. Adhering tags directly onto metal surfaces may result in
diminished read range and therefore should be avoided if possible.
