Guardian™ 500 Airflow Monitor Kit No 3944700 or 3944701

The Guardian 500 Airflow Monitor is designed to continuously monitor airflow through

enclosures and fume hoods. This permanently installed device provides both visual and audible

alarms to alert the user of abnormal airflow conditions. A green light on the front of the monitor

indicates normal flow conditions. When flow conditions lower than the set point are encountered,

a flashing red light is activated along with an audible alarm. To temporarily mute the audible

alarm, press and release the test/reset button. The Guardian 500 Airflow Monitor has a built-in

sensor, 3 relay inputs and 1 relay output. The relay inputs can be configured for night setback,

external alarm, and sash high alarm. The night setback features disables the alarm. The relay

output is configured for Low Air Alarm.

Component Identification

1. Air Inlet A portion of the air coming into the enclosure passes through the air

inlet and across the flow sensors.

2. Normal Flow Indicator This green light indicates normal flow conditions.

3. Alarm Indicator This red light is activated approximately 10-30 seconds after the low

flow set point is reached. Low flow set points are 10-20 fpm below

normal flow.

4. Mute Button If no alarm is present, this button will cause the red lamp to light and

the audible alarm to sound. If an alarm is present, the button will

silence the audible alarm.

5. Adjustment for Alarm Set

Point

This potentiometer is used to set the low flow indicators for the

alarm. It is adjusted with a small screwdriver.
