The SPM2000 (without display module) can be ordered preconfigured from the factory or it
can be field configured using the optional SPM7000 Setup Tool. The SPM7000 is a
hand-held, microprocessor-based, configuration tool which allows the user to connect to the
SPM2000, 2100, and 2200 transmitters. The SPM7000 comes with a plug-in coil
cord which allows for attachment to the display connector or directly to the transmitter. The
SPM7000 Setup Tool can be used to select the transmitters operational features, and
adjusts its setpoints. The tool also provides the ability, via a digital display, to read the actual
measurements being made in either feet per minute or inches of water. The tool has the ability
to upload previously stored configurations or download and store existing configurations.
Operation
The transmitter unit is connected to sensing probes located in the room and in the
hallway (or other reference space) by 1/2" O.D. sensor tubing. The pressure
difference between the two probes causes an extremely minute volume of air
(14 cubic centimeters per minute at 0.001" H
2O) to be induced through the velocity
sensor inside the transmitter. The low volume helps eliminate fouling dust. The
transmitter components then convert the electrical signals from the sensor into
either a velocity reading in fpm, or a pressure reading in "wc, depending on the
configuration.
The microprocessor in the transmitter then compares
the measurement with the desired polarity (direction)
and magnitude established by the adjustable alarm
setpoints. If the alarm limits are exceeded, the alarm
output contacts change to the alarm mode after the
selected delay time is exceeded.
In situations where an indication of the measured
velocity or pressure is required, and industry standard
4-20mA output signal is provided. This signal can be
used to drive a stand-alone indicator or to transmit to
the user's Building Automation System. The operational
range of this output can be set by the user to one of four
scales to provide the maximum resolution for a given
application.
The transmitter also has provisions for receiving input
signals from external contacts, buttons, or key switches.
The function of these inputs can be configured for either
a remote mute capability or the ability to remotely
establish the desired direction of airflow (polarity) for the
alarm operation. Remote muting allows the user to
extinguish the alarm horn from a remote location, such
as a nurses station. The polarity switching feature allows
the user to index the operation of the monitor to one of
four states: Negative, Neutral, Positive, or Standby. This
feature is extremely valuable when isolation rooms or
labs are not in use and monitoring is irrelevant during
maintenance.
