Guardian Digital 1000 Operation

The Guardian Digital Airflow Monitor consists of the airflow sensor, the Alarm Unit and the 15
VDC power supply. For 115V operation the alarm unit is powered by plugging the power
supply into the outlet on top of the fume hood or a building outlet. The alarm has “Enter”, “+”,
and “ – ” buttons to program the monitor. There is also a green LED “SAFE”, yellow LED
“CAUTION”, and red LED “LOW” with audible alarm for airflow conditions. The audible
alarm can be permanently muted if desired. The Guardian Digital 1000 Airflow Monitor
displays a face velocity value, provides an RS232 communications port to a PC or building
computer system, can be configured for external input connections such as night setback or
external alarm and provides up to three output relays that can be configured. For complete
detailed information, please refer to the separate Labconco 1000 Alarm User’s Manual provided
with the hood.

Guardian Digital 1000 Installation Procedure

1. The Fume Hood comes prepared to accept the Digital 1000 airflow alarm system.

2. First, remove the front panel by lifting it straight up and out away from the hood.

3. Next, remove the cover plate located at the top of the right corner post.

4. Install the monitor to the upper right corner post using the two screws that came with your

kit. See Figure 1.

5. The connection of the air sensor, adapter and hose will follow next.
a. Connect one end of the supplied sidewall adapter with nut included in your kit by

removing the uppermost plastic plug from the 1/2" hole in the sidewall of the hood and
replacing it with the adapter and nut. The nut is located inside the fume hood. See
Figure 2.

b. Cut 1.5" of the white hose (1.0" OD x .79" ID) supplied with your monitor. Connect one

end of the hose to the sidewall adapter. See Figure 2.

c. Connect the square air sensor to the other end of the white hose and be sure to connect

the sensor cable from the air sensor to the back of the monitor. This completes the
airway connection per Figure 2.

6. In your kit you will find an electrical cover plate and a snap-in electrical outlet. Snap the
outlet in place making sure that the outlet is secure.

7. Next, remove and discard the electrical cover plate that is on the junction box at the top of
your hood.

8. Wire the cover plate that you just prepared to the existing wires inside of the hood junction
box per the wiring diagram on top of the fume hood. WARNING: make sure that the power
is disconnected to your hood prior to connecting the new cover plate.

9. Secure the cover plate to the junction box with the existing screw.

10. Plug the output cord of the power supply to the back of the monitor and plug the power
supply into the outlet on the cover plate of the junction box.

11. Replace the front panel and calibrate your unit according to the instruction manual that came
with your monitor. For additional calibration guidelines follow the steps listed below.

Digital 1000 Calibration

1. Calibrate the airflow monitor according to the instruction manual that comes with the kit and

follow the steps listed below. To successfully calibrate, it will be necessary to change the face
velocity by moving the sash position. Typical calibration conditions are set at face velocity air
sample differences of at least 20 feet per minute. The airflow monitor is factory set to be
calibrated with a difference of at least 50 fpm and can be changed by changing the “lower/higher
air sample difference”. The following suggested in flow face velocity speeds are recommended
to successfully calibrate. Typical low air alarms are set 10-20 fpm below operational speeds.
Follow Step 2 below and review the Guardian 1000 Alarm User’s Manual that comes with the
airflow monitor.

2. Go to SETUP and then CONFIGURE, then go to CAL CONFIG MENU and change the

“lower/higher air sample difference” to 20 fpm. This will allow you to successfully calibrate with
values of a minimum of 20 fpm difference.

3. While in CAL CONFIG MENU, change the “sensor difference” from 10% to 3%.

4. While in CAL CONFIG MENU, adjust the red low air alarm to the desired setting such as 60

fpm. Then adjust the yellow “CAUTION or WARNING” to 63 fpm. Then adjust the
“CAUTION or WARNING” air reset to 3 fpm. This sets the alarm condition and can be altered
as desired.

5. To complete the CAL CONFIGURATION, be sure to enter “DONE”.

6. To start the calibration mode, use the Labconco 1000 Manual and enter “CALIBRATION” mode

on the display from the SETUP menu.

7. Follow the instructions on the display and alter the low face velocity by altering the sash position

to its most open position. Measure the average face velocity and enter the low value on the
display. Be careful not to block the opening. The low exhaust velocity calibration will take
about 5 seconds.

8. Now alter the high exhaust velocity by altering the sash position to a lower open position.

Measure the average face velocity and enter the high value on the display. The high value must
be at lease 20 fpm greater than the low value. The high exhaust velocity calibration will take
about 5 seconds.

9. Be sure to enter “DONE” after successfully completing the low and high calibration set points.

10. Once calibration is completed go to “RUN” and hit “ENTER”. The value should read close to the

high calibration set point where the sash was left in its last position.

11. Recheck the face velocity with an anemometer to confirm the display on the digital airflow

monitor at various sash positions.
