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 factory-prepared digital airflow monitor socket. For 230V operation, the Alarm

Unit is powered by plugging the power supply into 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 enclosure.

Installation Procedure

1. The enclosure comes prepared to except the Guardian™ Digital airflow monitor system.

2. First remove the large 1.19" dia. gray hole plug. See Figure 1. See Figure 2 only to

reference internal assembly of the airflow monitor. Locate the elbow, locknut, and washer

and install it in the 1.19" dia. hole per Figure 1 and Figure 2. The enclosure baffle pivots

down to install the elbow, washer and locknut.

3. Cut the 1" hose supplied with the kit to 10.5" approximate length and install it between the

airflow sensor and the elbow.

4. Secure the Guardian Digital alarm to the enclosure with double stick tape as shown in

Figure 3. The airway passage between the alarm module and the enclosure is now

complete.

5. Locate the metal hose cover and install with double stick tape per Figure 3. (Omit this step

on the Protector Work Stations.)

6. Locate the power supply transformer. One end should already be connected to the two-

pin connector labeled 15 VDC on the back of the alarm module and through the strain

relief bushing. If disconnected, then reconnect to power the airflow monitor. Plug the

115V power supply into a standard 115V duplex receptacle, the back of the accessory

FilterMate portable exhauster or the back of the accessory light. For 230V, plug into a

standard receptacle with your specific outlet plug. (It is recommended that the airflow

monitor be connected directly to the FilterMate switched auxiliary outlet so the

airflow monitor is powered at the same time.)

7. Installation is now complete.

Digital 1000 Calibration 1. Calibrate the airflow monitor according to the instruction manual that comes with the kit. To successfully calibrate, it will be necessary to change the face velocity by adjusting the airflow exhaust volume. The exhaust volume can be adjusted with the speed control on the FilterMate or by using an adjustable damper on the exhaust blower. Typical calibration conditions are set at face velocity air sample differences of at least 20 feet per minute.

Digital 1000 Alternate Calibration Procedure - Constant Volume Conditions 1. To successfully calibrate, it will be necessary to change the face velocity by opening and closing the enclosure’s sash. The airflow monitor is factory set to be calibrated with a difference of at least 50 fpm and can be changed by adjusting the “lower/higher air sample difference”. The in flow face velocity speeds provided in the chart below are suggested to successfully calibrate the Digital 1000. 2.

thermo anemometer. Enter the high value set point on the display. The high value must be at least 10 fpm greater than the low value. The high exhaust volume 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. 11.
