INTRODUCTION TO TR50
1.1 Introduction
The TR50 IAQ (Indoor Air Quality) Sensor is an advanced, configurable device for
commercial buildings. It monitors 5 parameters
• Temperature (T)
• Relative Humidity (RH)
• Carbon Dioxide (CO2)
• Particular Matter (PM1.O, PM2.5 and PM10)
• Total Volatile Organic Compound (TVOC)
This TR50 IAQ Sensor device communicates using the Modbus, BACnet MS/TP, or
SylkTM Bus protocol and easily integrates with the building management system.
The algorithm built into the device can calculate comprehensive air quality level
and display AQI (Air Quality Index) number in LCD and corresponding color with
LED ring. The device is packaged with numerous presets suitable for most
commercial building requirements, enabling a quick and easy initial setup.
The TR50 IAQ Sensor device has two display modes:
• With Display (With Touch Button)
• Without Display (Without Touch Button)

INSTALLATION
2.1 Important Safety Information and Installation
Precautions
Read the below instructions carefully for safety and installation.
Local codes and practices
Always install equipment in accordance with the National Electric Code and a in
manner acceptable to the local authority having jurisdiction.
Electrostatic sensitivity
This product and its components may be susceptible to Electrostatic Discharge
(ESD). Use appropriate ESD grounding techniques while handling the product.
When possible, always run the product by its non-electrical components.
High voltage safety test
Experienced electricians, at first contact, always assume that hazardous voltages
may exist in any wiring system. A safety check using a known, reliable voltage
measurement or detection device should be made immediately before starting
work and when work resumes.
Lightning and high-voltage danger
Most electrical injuries involving low-voltage wiring result from sudden,
unexpected high voltages on usually low-voltage wiring. Low-voltage wiring can
carry hazardous high voltages under unsafe conditions. Never install or connect
wiring or equipment during electrical storms. Improperly protected wiring can have
a fatal lightning surge for many miles. All outdoor wiring must be equipped with
adequately grounded and listed signal circuit protectors, which must comply with
local, applicable codes. Never install wiring or equipment while standing in water.

TR50 - User Guide 5
Wiring and equipment separations
Install all the wiring and controllers to minimize the possibility of accidental
contact with other potentially hazardous and disruptive power and lighting wiring.
Never place 24 VAC or communications wiring near other bare power wires,
lightning rods, antennas, transformers, or steam or hot water pipes. Never place
the wire in any conduit, box, channel, duct, or other enclosure containing power or
lighting circuits. Always provide adequate separation of communications and
another electrical wiring according to code. Keep wiring and controllers at least six
feet from large inductive loads (power distribution panels, lighting ballasts,
motors, etc.). Failure to follow these guidelines can introduce electrical
interference and cause the system to operate erratically.
Warning
By using this Honeywell literature, you agree that Honeywell will have no liability
for any damages arising from your use or modification to the literature. You will
defend and indemnify Honeywell, its affiliates, and subsidiaries from and against
any liability, cost, or damages, including attorneys' fees, arising out of or resulting
from any modification to the literature by you.
The material in this document is for information purposes only. The content and
the product it describes are subject to change without notice. Honeywell makes no
representations or warranties to this document. In no event shall Honeywell be
liable for technical or editorial omissions or mistakes in this document, nor shall it
be liable for any damages, direct or incidental, arising out of or related to the use of
this document. No part of this document may be reproduced in any form or by any
means without prior written permission from Honeywell.
2.1.1 Before Installation
1. Read these instructions carefully. Failure to follow them could damage the
product or cause a hazardous condition.
2. Check the ratings given in the instructions and the product to ensure the
product is suitable for your application.
3. TR50 IAQ Sensor must be installed and mounted only by authorized and
trained personnel.
4. When performing any work (installation, mounting, start-up), all manufacturer
instructions, particularly the Mounting Instructions (31-00566M-01), are to be
observed.
5. It is recommended to keep the device at room temperature for at least 24 hours
before applying power. This allows any condensation resulting from low
shipping/storage temperatures to evaporate.
6. After installation is complete, check out product operation as provided in these
instructions.
Note: All wiring must agree with applicable codes, ordinances, and regulations as
specified in installation wiring diagrams.

2.1.2 Restricting Access to Network
Prevent unauthorised access to the network (e.g., BACnet MSTP, Modbus, or
SylkTM bus) that the Smart Sensor uses. With any system, preventing physical
access to the network and equipment reduces the risk of unauthorised
interference. When using open protocols such as Modbus or BACnet MSTP, care
should be taken to ensure that the physical network is protected from
unauthorised access.
2.2 Steps to Install TR50 Sensor
1. Switch OFF the power supply before initiating the TR50 IAQ Sensor installation.
2. Loosen the bottom screw by turning it anticlockwise with the help of a
screwdriver.

2.3 Wiring Connections
Below are the wiring details of RS-485 via communication BACnet, Modbus and
SylkTM Bus through plant or unitary controller.
2.3.1 Wiring Terminals
Follow the below steps to do wiring for two wires into one terminal:
Step 1. Strip 1/2 inch (13 mm) from the wires to be attached at one terminal.
Step 2. Twist the wires together with plier. (A minimum of 3 turns).
Step 3. Cut the twisted end of wires to 3/16 inch (5 mm) before inserting into
terminal and tightening screw. Then pull on each wire in all terminals to
check for mechanical connection.

2.3.2 SylkTM Bus Wiring
a For Spyders, use the Resource Usage View in the Spyder Tool to determine
maximum number of devices. For Comfort-PointTM Open controllers, there is a
maximum power consumption 1.6 W
Note: When the SylkTM Bus load is above 1 W, the interval report time must be specified
carefully.
b As a rule of thumb, single twisted pair (2 wires per cable only), thicker gauge, non-
shielded cable yields best results for longer runs.
c The 30 m distance for standard thermostat wire is conservative, but meant to
reduce the impact of any sources of electrical noise (including but no limited VFDs,
electronic ballasts, etc). Shielded cable recommended only if there is a need to
reduce the effect of electrical noise.
d These distances also apply for shielded twisted pair.
2.3 Power Up the Sensor Device
Once the TR50 IAQ Sensor device is installed and powered, the device gets started
and shows firmware version number “x.x.x.x” as per the latest updated firmware
and the parameter values are displayed on the LCD.
Note: The current firmware version number is 0.1.1.0. It can be updated if there is any
firmware update in the device.
