Technical Specification Sheet Rev. 2, April, 2001 Document No. 149-293P25 Page 1 of 4 Fume Hood Monitor Figure 1. APOGEE Fume Hood Monitor. The APOGEE™ Fume Hood Monitor* (FHM) is a laboratory fume hood safety device which provides continuous measurement and display of fume hood face velocity. The Fume Hood Monitor is the only device available packaged with a service program to install it, start it up, and calibrate it in accordance with laboratory and fume hood performance listing guideline. The FHM alerts the Fume Hood user with an audible and visual alarm in the event of a fume hood exhaust system failure. It is designed to operate as a standalone monitor and as an integral networked component of the APOGEE Automation System to ensure user safety of constant volume fume hoods. The FHM utilizes through the wall, thermal anemometer velocity measurement technology. The sensor, mounted within the FHM electronic assembly, measures the velocity of the airflow moving through the fume hood via a sampling tube connected to the fume hood wall. *Patent No. 5439414 The location of the sample tube is critical to the proper operation of the monitor. The Fume Hood Evaluation Kit, part number 546-00320 will aid an installer in locating the proper location of the sample tube to obtain an accurate velocity measurement. This velocity measurement is calibrated to match the average velocity of air moving through the sash face opening. Local user alarms for high and low face velocity provide visual and audible annunciation whenever the measured face velocity exceeds the user defined alarm limits. The emergency push-button allows the user to annunciate an emergency condition at the fume hood such as a chemical spill. All alarms can be sent out over the APOGEE network or to a remote alarm horn via the integral digital output (DO) point. For fume hood exhausts that are turned off or setback during unoccupied hours, the FHM provides an unoccupied mode, which can be set via a local switch and over the APOGEE network. The unoccupied mode eliminates unnecessary alarms when the laboratory is not is use. The FHM also has an integral digital input (DI) point which provides additional features at the fume hood such as monitoring the sash height, initiating an auxiliary alarm, or connecting to a remote occupied/unoccupied switch. Networked Fume Hood Monitors throughout your entire facility are integrated to a central safety or maintenance workstation (see Figure 2) to ensure immediate response to critical alarms and to continuously archive fume hood-operating conditions for regulatory compliance.
