The Triatek FMS-1655L Room Pressure
Controller is an ultra-sensitive instrument
used to control and/or monitor air pressure
in hospital rooms, labs, and clean rooms. It
is capable of measuring and displaying air
pressures down to 0.0001” wc.
Features include:
•
Digital display of pressure with a
programmable description
•
Full-color touchscreen with audible and
visual alarms
•
Patent-pending Safety Halo™ with 180
°
edge lighting
•
Four relay outputs for transmitting alarm
conditions to a remote location such as a
central monitoring station
•
Auxiliary analog inputs for use with
optional sensors
•
Analog outputs used in control
applications
•
Dual sensor split screen viewing mode
•
Password protection of programmed
setup
•
Optional keylock switch for isolation
select protection
•
Comprehensive real-rime diagnostics
tool built into each unit
The FMS-1655L has enhanced graphics and
Saftey Halo™ edge lighting that provides a full
180° of status visibility. The product is shipped
with the Safety Halo
TM
at full brightness, but
may be dimmed or even disabled completely
using the
Display Setup
menu.
Bright graphical color changes are used
to indicate the three different statuses
of the monitored space. These graphical
backgrounds indicate
Normal
when the room
pressure is within defined limits,
Warning
when the room pressure is approaching
an out-of-limits condition, and
Alarm
when
the room pressure is outside the defined
acceptable and safe limits.
The room pressure ranges are configured
by the user, either directly from the display
or over the network from the building
management system (BMS). Room pressure
selection of positive, negative, or no isolation
is set using the user menu or an optional
keylock switch.
Alarm conditions are defined by the user
in terms of desired pressure settings for
the room being monitored. When an alarm
condition occurs, it can be annunciated
in four ways: 1) on the display, 2) with an
audible alarm, 3) transmitted via contacts
to a remote monitoring station, and 4) over
the LonWorks
®
network. The alarm will
automatically reset when the unit senses that
room pressure has returned to proper limits,
or the attendant can mute the audible alarm
by touching the
Alarm Audible
button at the
bottom of the screen.
The FMS-1655L provides four relay outputs
that can be used for remote alarms or pilot
control functions. The operation of each relay
can be configured to trigger on defined control
functions of the FMS-1655L, except for Relay
2, which is reserved for the display power
control.
It is often important to have room variables
such as temperature or relative humidity
displayed along with the room pressure.
These variables can be enabled or disabled
by the user in the
Display Setup
menu.
The FMS-1655L provides additional analog
inputs which can be configured for 4-20 ma
current or for voltage input signals. The input
can be scaled as needed to display correct
values, and a suitable description can be
applied.
The FMS-1655L provides analog outputs
which can be set up for 0-5v or 0-10v output.
It can be programmed to be a proportional
output for providing a linear signal to an
automation system, or programmed for a
PID floating point output for direct control of
damper actuators, speed drives, etc.
When configured for dual sensor mode (see
page 35), the FMS-1655L can monitor a
secondary pressure and display its real time
measurement on the screen along
with the primary pressure in a split screen
vie
w (see Figure 4). This secondary
monitored pressure re
ading has no alarming
capabilities and is for display purposes
only. The Safety Halo™ edge lighting
continuously displays the alarm status of the
primary channel, and is not affected by the
secondary channel.
The user can set multiple access level
passwords to protect against unauthorized
access to the FMS-1655L.
The FMS-1655L provides built-in diagnostic
tools for troubleshooting during installation,
including manual override capabilities and
a comprehensive real-time view that allows
the real-time values and states of each
analog and digital input and output to be
conveniently displayed. This tool facilitates
the verification and certification processes
conducted by test and balance personnel
during commissioning. 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.
