Fire condition detection and control system for air moving and filtering units

A fire condition detection and control system for air moving and filtering units comprising:

• a fire condition unit including a housing, fire condition sensing means associated with said housing for sensing a condition indicative of fire, such as smoke or heat, transmission means associated with said housing for transmitting a fire condition alarm signal following activation of said fire condition sensing means;
• and
• a remote air moving and filtering unit including a housing having an air inlet and an air outlet, filter means within said housing for filtering air drawn through said air inlet, a blower means for drawing air through said air inlet and through said filter means and for expelling filtered air through said air outlet, receiver means for receiving the fire condition alarm signal as a result of a condition indicative of a fire sensed outside of said remote air moving and filtering unit, and control means for disabling the blower means upon receipt of the fire condition alarm signal.

A fire condition detection and control system for use with air moving and filtration units having an electrically-powered blower motor associated therewith, the system comprising:

• a fire condition detection unit including a fire condition sensing means for sensing characteristics of a fire, such as smoke or heat, outside of the air moving and filtration units, and transmission means for transmitting a fire condition alarm signal following activation of said fire condition sensing means;
• and
• a control unit including an electrical inlet means for receiving a source of electrical power, an electrical outlet means for providing electrical power from said inlet to an outlet, said outlet adapted to be connected with an air moving and filtering unit, switch means for interrupting the electrical path between said inlet and said outlet, receiver means for receiving the fire condition alarm signal when fire is sensed outside of the air moving and filtering units, and control means for activating said switch means to interrupt the electrical path between said inlet and said outlet upon receipt of the fire condition alarm signal by said receiver means.
