Understanding Alarms
Low Battery Alarm
The Low Battery Alarm will sound an intermittent electronic beep
indicating that there is approximately fifteen (15) minutes of remaining
battery capacity. The delays between beeps will get shorter and
shorter as time runs out. The battery indicator LED will turn red.
Low Flow Alarm
The Low Flow Alarm will sound a continuous electronic
beep indicating that the flow to the hood has dropped below
the designed specification of 185 L/min (6.5 CFM).
Active Flow Technology
The Active Flow Technology automatically responds to a wearer’s
need for more or less airflow by continually monitoring and adjusting
airflow to keep it constant at the design set point regardless of filter/
cartridge type, hood type, filter loading or battery capacity.
High Temperature
The turbo-blower unit is designed to shut down if operating
temperatures reach 50°C (122°F) and sound an audible alarm.
