Remote monitoring of remediation systems

A remote monitoring system for remotely testing at least one remediation system installed within a building or structure, each remediation system including a ventilation fan and an exhaust conduit, the remote monitoring system comprising:

• a sensor adapted to sense the presence of airflow within the exhaust conduit;
• an interface in communication with the sensor and a switch for switching the ventilation fan between an on and off position, the interface adapted to convert sensor signals received from the sensor into an output signal;
• and
• a gateway in communication with the interface, the gateway adapted to transmit said output signal to a remote computer located away from the building or structure;
• wherein the remote computer is configured to send one or more test signals to actuate the ventilation fan between said on and off positions and is further configured to analyze the output signals received from the sensor during each of the on and off positions.
