The Triatek HMS-1650 Series Fume Hood Controller is an ultra-sensitive
instrument used to monitor and/or control the fume hood face velocity in
laboratories and clean rooms. This unit is a precision measuring system
capable of measuring and displaying face velocities from zero to 200 ft/
min (1.016 m/sec) with an accuracy of ±2 ft/min.
Key features of the HMS-1650 include:
• Comprehensive closed-loop sash control with sidewall velocity
sensing
• Full-color touchscreen display with programmable display options and
adjustable backlight
• Intuitive user interface simplifies setup and configuration of unit
• Display background changes color to indicate hood status at a glance
• Audible and visual alarm annunciation
• Auxiliary universal analog inputs for use with optional sensors
• Four independent PID control loops for controlling damper actuators,
speed drives, hot water valves, humidifiers, etc.
• Digital input used to monitor an optional fume hood sash switch, zone
presence sensor, or emergency override switch
• Relay outputs used for transmitting alarm condition to remote location
• Dedicated thermistor inputs for temperature monitoring and/or control
applications
• Multi-level password protection of touchscreen user interface
• Field Calibration of both sidewall velocity sensor and optional sash
position sensor
• Multi-protocol native (BACnet®, Metasys® N2) for easy integration
with any BMS
• Manual override of Analog and Relay outputs assist with Test &
Balance procedures
• Comprehensive Real-Time View diagnostics tool displays built-in to
each unit
• Easy-to-install backplane/backplate assembly facilitates permanent
termination of all wiring
The HMS-1650 is equipped with a 3.2” diagonal Full-color
Touchscreen display in portrait orientation (240 x 320). The password-
protected menu tree is very intuitive and simplifies the setup and
configuration of the unit. The menus incorporate touch-based interfaces
such as sliders, radio buttons, and dialog popups to facilitate the ease-
of-use of the HMS-1650.
The display implements bright background color changes to indicate the
three different Alarm Status indications of the monitored fume hood.
These background colors indicate “Normal” when the face velocity is
within defined limits, “Warning” when the face velocity is nearing an out-
of-limits condition, and “Alarm” when the face velocity is outside defined
acceptable limits. The face velocity ranges for these conditions are
easily set by the user for the specific installation when necessary. The
background color changes provide an overview of the monitored fume
hood face velocity conditions at a glance.
Alarm conditions may be defined by the user, in terms of desired face
velocity settings for the fume hood being monitored. When an alarm
condition occurs, it may be annunciated in four user-definable ways: 1)
on the display, 2) with an audible alarm, and 3) transmitted via contacts
to a remote monitoring location and 4) over the BMS network. The alarm
will automatically reset when the unit has sensed that the fume hood
face velocity has returned to proper limits. The operator may easily mute
the audible alarm by touching the OK button on the alarm notification
message popup window of the touchscreen display.
For many applications, it is important to have other variables such as
sash position or ambient temperature displayed along with the fume
hood face velocity. The HMS-1650 provides for this by means of three
additional Universal Analog Inputs, each of which may be configured
for either current loop operation or voltage input operation (0-5V, 1-5V,
0-10V, 2-10V, 0-20mA, 4-20mA). Each input may be scaled as needed
to display correct values, and may have an engineering units selection
associated. The configuration of each analog input is field selectable
through the use of miniature dipswitches on the controller unit.
For those applications requiring monitoring and/or control based
on temperature variances, the HMS-1650 provide two dedicated
Thermistor Inputs in addition to the four universal analog inputs.
Therefore, a total of six analog inputs are available for control
applications. The two thermistor inputs may be used with negative
temperature coefficient (NTC) Type 2 or Type 3 sensors.
The HMS-1650 provides four Universal Analog Outputs, which may
be configured for either current loop operation or for voltage operation.
Each analog output may be configured for proportional operation to
provide a linear signal to the BMS, or for PID (proportional-integral-
derivative) control operation for closed-loop feedback control of
damper actuators, variable frequency (speed) drives, hot water valves,
humidifiers, or other analog-controlled devices. Each universal analog
output may be field-configured for the required application using onboard
configuration dipswitches on the controller module. Each analog output

may also be temporarily overridden using the built-in diagnostic tools for
troubleshooting during the installation and commissioning phase.
The HMS-1650 provides four Digital Inputs that may be used for
monitoring sash switches, override switches, flow switches, occupancy
sensors or other devices with binary outputs. The configuration and
operation of each input may be configured by the user to define
the effect of a change in its state. Each digital input may have a
programmable delay duration associated with it. Each digital input may
be configured for either normally-closed or normally-open operation, and
may also be configured to be active-high or active-low triggered. The
global configuration of the digital inputs is field selectable through the
use of a configuration switch on the controller unit.
The HMS-1650 provides four Relay Outputs, which may be configured
for either direct-acting or reverse-acting operation, and may have a
programmable delay associated to meet the specific needs of the
required application. A unique feature of the HMS-1650 is its ability to
trigger a relay output for the purpose of activating an optional automatic
sash closer device, thereby keeping an unattended fume hood with
an open sash safe for occupants of the lab. Each relay output may
also be temporarily overridden using the built-in diagnostic tools for
troubleshooting during the installation and commissioning phase.
The user may set up multiple multi-level Passwords to prevent
unauthorized or casual access to the HMS-1650 configuration settings.
Up to ten passwords of up to eight digits may be programmed, with
each having one of four associated access levels. Administrators and
Facility Management personnel may have unrestricted access, while
general staff may be assigned restricted access passwords which limit
the functionality of the user menus.
Fume hood operating mode selection of Occupied, Unoccupied, or
Standby may be protected using limited access passwords, thereby
eliminating the need for keylock switches and keys. However, an
Optional Keylock Switch may be used to further control access to
change in operating modes.
The HMS-1650 provides a unique set of built-in diagnostics tools that
are extremely valuable for facilitating the troubleshooting process during
the installation and commissioning phase. Included in these built-in
diagnostics tools are Manual Override capabilities for both analog
outputs and relay outputs, and a comprehensive Real-Time View
capability that allows the real-time values and states of each analog
and digital input and output to be displayed conveniently. This is an
extremely useful tool that facilitates the verification and certification
processes conducted by typical test and balance personnel during
the commissioning of the system. There are also options for storing
configuration settings and for restoring those settings, as well as
performing a complete restoration of the factory default configuration
settings.
The HMS-1650 touch-screen user interface incorporates an easy-to-use
Manual Override capability that allows the unit’s analog and digital
outputs to be overridden independent of their proportional or PID loop
control operation. This is an extremely useful function that facilitates the
verification and certification processes conducted by typical Test and
Balance personnel during the commissioning of the system.
The HMS-1650 incorporates an innovative Backplane/Backplate
assembly which greatly facilitates the installation process and permits all
wiring terminations to be permanent. The HMS-1650 serves as a direct
drop-in functional replacement for all previous models of HMS-1600
series of BACnet/N2 fume hood controllers.
Depending upon the actual model number ordered, the HMS-1650
may be accompanied by one of two types of sidewall sensor
modules for measuring face velocity. The standard sidewall sensor
includes a 9-pin pluggable terminal block connector, while the
Honeywell sidewall sensor includes a 3-position terminal strip.
See pages 13 through 14 for physical representations of the two
sidewall sensor options.

This section will illustrate a typical method of installing the HMS-1650
to a fume hood. Tools required include: drill, 3/8 drill bit, 1/8 drill bit,
Phillips #2 screwdriver, standard medium blade screwdriver, silicone
sealant.
Depending upon the actual model number ordered, the HMS-1650
may be accompanied by one of two types of sidewall sensor
modules for measuring face velocity. See pages 15 through 18 for
physical representations of the two sidewall sensor options.
1. Proper location of the sensor is very important for obtaining
the best possible operation of the HMS-1650. The system
uses through-the-wall sensing to measure the internal negative
pressure of the fume hood to accurately determine the face
velocity. The sensor must be located in a position that is least
affected by turbulent air within the hood. See illustration on page
16. There are two types of fume hood arrangements which need
to be considered: By-Pass and Non-By-Pass.
• Front-to-Back Position – With either type of fume hood
arrangement, the sensor is best located approximately 6
inches back from the vertical sash track.
• Vertical Position (By-Pass type) – Locate the sensor
vertically in the center of the region between the bottom of
the sash in the fully open position and the bottom edge of the
by-pass opening.
• Vertical Position (Non-By-Pass type) – Locate the sensor
vertically 6” above the bottom of the sash in the fully open
position.
2. See page 16 for dimensions and suggested mounting
arrangements of the Triatek flow sensor on the hood wall. NOTE:
Be certain that sensor reference port is in laboratory room
air. If necessary to obtain this, use Triatek HMS-1600-PLATE
mounted on exterior panel of the fume hood.
3. Apply silicone sealant around the sensor immediately prior to
mounting the assembly to its mounting surface. Be careful to
avoid getting sealant in the sensor port.
4. See page 12 for mounting details for the HMS-1650 display unit.
The preferred location is eye level, usually on one of the side
bezel panels. Please note that the display unit is cable connected
to the control unit, and provision must be made to route the cable
without interference with the fume hood sash or sash cable. The
control unit is typically secured in a convenient location on top of
the fume hood. (See page 13)
5. For standard sidewall sensors, at the HMS-1650 backplane,
assuming the colors of the 3-conductor signal cable being red,
black, and white, connect the leads to the terminals as follows:
Red: SNS_PWR
Black: AGND
White: AI_1
If a Honeywell sidewall sensor is being used, the signal cable
leads should be connected to the HMS-1650 backplane terminals
as follows:
Red: +10V
Black: AGND
White: AI_1
For standard sidewall sensor modules with the 9-pin terminal
block, connect the 3-conductor signal cable as follows:
Red: +Vin
Black: GND
White: Vo
For Honeywell sidewall sensor modules with the 3-position
terminal block, connect the 3-conductor signal cable as follows:
Red: +
Black: G
White: IN
6. Power supply connections - input voltage must be Class 2, 24
VAC or 24 VDC. A step-down isolation transformer is supplied
with the HMS-1650. Triatek recommends that the HMS unit be
powered using the supplied transformer, and that only one unit be
powered with each transformer. Do not power any other device
with the same transformer. See pages 26 and 27 for connection
details.
7. All wiring should conform to the Local Regulations and the
National Electrical Code. Take precautions to prevent routing the
sidewall sensor wiring in the same conduit as line voltage or other
conductors that supply highly inductive loads such as generators,
motors, solenoids or contacts, etc. For all wiring connections, use
22 AWG or larger.
8. After the installation is complete, apply power to the unit, open
the sash to a normal operating position and observe the flow
reading on the touchscreen display. If necessary, proceed to the
Programming Section beginning on page 31.
