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.
Calibration
The filtered enclosure comes factory calibrated with the monitor alarm at 60 ± 10
fpm with the inflow velocity set at 90± 10 fpm.
Programming the Guardian 1000 Digital Alarm
Set the desired face velocity of the enclosure with the sash in the down position
using an average face velocity of readings from a thermal anemometer.
a. 2 ft enclosure – 2 readings
b. 3 ft enclosure – 3 readings
c. 4 ft enclosure – 4 readings
Configure Alarm
To successfully calibrate the airflow monitor, it will be necessary to change the
face velocity by adjusting the airflow exhaust volume. The exhaust volume can be
adjusted using the speed control located behind the front panel on the XPert
Filtered System. For the XPert Filtered Station, the exhaust volume is adjusted
through a damper in the building exhaust system.
The following inflow face velocity speeds are recommended to successfully
calibrate. To begin, determine what the low airflow, low warning airflow, normal
airflow, and high airflow shall be.
