A display is normally used with the transmitter. Three yellow "Set

Point" indicators are provided on the display face, one of which will

be lit to show the desired direction of airflow and pressurization

level. The lit set point indicator will flash periodically to provide a

visual indication that the monitor system is functioning properly.

The "Status" indicators provide a graphic indication of the level of

pressurization. These dual colored, light emitting diodes (LEDs)

indicate status with the color green for normal and red for an off

normal condition. When the pressurization level is normal, the green

status indicator directly under the yellow set point indicator will be

lit. Should the pressure level decrease or increase outside of the

alarm limits, the normal indicator light will turn off and the

appropriate indicator to the left or right of the normal light will turn

red.

A large red LED alarm indicator is provided to display the presence

of an alarm condition. This indicator flashes when

Communication

The SPM2000 Iso-Tek Transmitter is capable of digital

communications on an RS485, two conductor network cable at

9600 baud. Up to 255 units can be addressed on one network. Two

communications protocols are available to the user: Tek-Air Open

Protocol, and JCI N2 Protocol. In both cases, the SPM2000

Iso-Tek can share the network with Tek-Air's FVC2000

Fume Hood Controllers. In the case of N2 Protocol the JCI

N2 compatible units can also share the network with Tek-Air units.

Open Protocol allows the SPM2000 Iso-Tek Transmitter

to interface with the Honeywell Excell system.

Tek-Air will make the communications protocol available to any

control system manufacturer, (call factory for more information).

Data communicated to the remote system includes transfer air

velocity, alarm setpoints, and alarm status. Parameters, which can

be modified by the remote system, include alarm setpoints, and air

flow polarity.

an alarm condition has occurred for a length of time exceeding the

selected time delay period. An audible alarm horn is built into the

display; this sounds in conjunction with the LED alarm indicator.

When the alarm is acknowledged by pressing the MUTE button, the

horn will silence and the LED alarm indicator will provide a steady

red indication. This will continue as long as the alarm condition still

exists.

When placed in "Inactive" or "Standby" mode the setpoint lights and

alarms are deactivated. However, the status lights continue to

operate as the transmitter continues to monitor room pressure.

All LED indicators are raised from the case slightly to provide

adequate viewing from any angle. The LED alarm indicator can be

seen from fifty feet away in normal ambient lighting conditions. This

allows the display to be mounted in locations which are out of reach

to those who would tamper with the unit.

Room Pressure Control

Tek-Air offers a complete line of products that can be used for

critical controlled spaces for isolation of disease and clean room

environments. The pressure differences to these critical spaces can

only be done efficiently with quality control instrumentation and

control valves, (standard VAV box type controllers should be

avoided). The Iso-Tek SPM2000 series transmitter as a pres-

sure monitor has the capability to monitor and alarm when a control

system is not at design conditions due to a door opening, fan failure

or HEPA filter blocking. Tek-Air’s Multipurpose Valve

(MPV), used with a KSA7000 Electric Key Switch and

SPM2000 Space Pressure Monitor, can provide a flexi-

ble system to the facility operators to keep the isolation suite or

clean room manufacturing space at design conditions when it is part

of a dynamic ventilation control system. For more help, please call

your local Tek-Air Systems Integrator to get additional applications

information.
