Exhaust System Alarm
The Axiom is unique in its response to an exhaust alarm. Instead of shutting
off the BSC’s blowers, the Axiom starts its “Activate Protection Protocol” – a
certifier-programmed interval of up to 5 minutes. During this interval, the
Axiom’s exhaust blower speeds up to compensate for the loss of the remote
exhaust fan to provide constant inflow. The supply blower maintains
downflow. This offers the user time to secure any hazardous material in the
BSC. At the end of the Active Protection cycle, the supply blower shuts off,
followed by the exhaust fan 10 seconds later, to ensure containment until
the unit shuts off completely.
