- Page 6 General Description ® The AirGard 405 monitor is designed to continuously monitor airflow through fume hoods. This permanently installed device provides both visual and audible alarms to alert you of abnormal airflow conditions after the instrument is calibrated for the particular installation.
- Page 7 Two screws secure the monitor to the 1. MOUNTING SCREWS back plate which is then secured to the fume hood. 2. AIR INLET A portion of the air coming into the hood passes through the air inlet and across the flow sensors. This potentiometer is used to set low 3.
- Page 8 Setup ® The AirGard 405 fume hood monitor contains several configuration options. Two connectors provide access to remote control devices and firmware configuration jumpers. Observe the back of the monitor. Locate the two connectors at the left-center of the printed circuit board marked J3 and JP1.
- Page 9 Pole 1 of JP1 is used to select the relay configuration. Without the jumper installed, the relay is Normally Closed (NC) during normal airflow and Normally Open (NO) during an alarm condition. Installing a shorting jumper across pole 1 will cause the relay to be Normally Open (NO) during normal airflow and Normally Closed (NC) during an alarm condition.

- Page 11 N O T I C E If the monitor is to be installed in a hood with Hardiboard™ fiber-cement side panels or similar material, use special drill bits designed for glass and other hard, abrasive materials. W A R N I N G Older hoods may contain asbestos.
- Page 12 Step 6: Connect the supplied air hose between the sidewall adapter (figure 4) and the flow tube through the back plate orifice (figure 3). Secure hose firmly and cut to length as necessary to prevent accidental kinks and bends which can affect calibration.
- Page 13 Calibration Field calibration must be performed since each hood installation is unique. W A R N I N G Calibration of this instrument should only be performed by qualified personnel. Proper guidelines for monitoring any ventilation apparatus are established on the basis of toxicity or hazards of the materials used, or the operation conducted within the ventilation apparatus.
- Page 14 Step 4: Adjust fume hood airflow to the low flow setpoint (as described in Step 3). One method to lower the face velocity of the hood is to close the volume damper (if available) in the ductwork. W A R N I N G This method is only used as a temporary condition to set the low flow point.
- Page 15 Step-By-Step Operation Alarm Acknowledgment The horn and red indicator will turn on approximately six seconds after an alarm condition is detected.
