Monitor and alert the operator to low airflow conditions.
Mount atop Protector XVS Ventilation Stations, Protector Demonstration Hoods and Protector Work Stations in factory prepared location. Include face plate with circuit board, electrical power pack, tubing, airflow tube adapter and glacier white epoxy-coated steel casing. From the monitor’s face plate, the user can easily select and calibrate a setpoint between 30 and 250 fpm using a velocity meter and a screwdriver. A green LED glows to indicate “safe” when airflow is greater than the low setpoint. A red LED flashes to indicate “low” when airflow is below the low setpoint. An amber LED flashes when then the sash is raised above the maximum safe working opening. An audible alarm sounds (and can be muted) when under “low” and “sash high” conditions. Include night setback, external alarm and alarm mute functions.
