An aspirated detector system comprising: a first ambient air input network coupled to a first fan operating continuously, wherein the first ambient air input network includes a first plurality of spaced apart intake points; a second ambient air input network coupled to a second fan different than the first fan, wherein the second ambient air input network includes a second plurality of spaced apart intake points, wherein the first ambient air input network and the second ambient air input network are substantially identical, and wherein the first fan and the second fan both operate at a common speed; an ambient condition detector including a multi-channel aspirated smoke sensor having primary and redundant smoke sensing chambers coupled to the first ambient air input network and the second ambient air input network respectively; a timer; and control circuits that are configured to calculate a pre-recorded series of transport times correlated to the second plurality of spaced apart intake points based on a power value of the second fan and a pipe geometry of the second ambient air input network and store the pre-recorded series of transport times as a table in a memory device, wherein the control circuits are configured to activate the second fan to draw in ambient air when smoke aspirated from the first ambient air input network triggers an alarm associated with the ambient condition detector, wherein the control circuits, simultaneously with activation of the second fan, are configured to start the timer to count a transport time between the activation of the second fan and when the smoke aspirated from the second ambient air input network reaches the ambient condition detector, and wherein the control circuits are configured to compare the transport time with the pre-recorded series of transport times stored in the memory device to provide a location of the smoke. a first ambient air input network coupled to a first fan operating continuously, wherein the first ambient air input network includes a first plurality of spaced apart intake points; a second ambient air input network coupled to a second fan different than the first fan, wherein the second ambient air input network includes a second plurality of spaced apart intake points, wherein the first ambient air input network and the second ambient air input network are substantially identical, and wherein the first fan and the second fan both operate at a common speed; an ambient condition detector including a multi-channel aspirated smoke sensor having primary and redundant smoke sensing chambers coupled to the first ambient air input network and the second ambient air input network respectively; a timer; and control circuits that are configured to calculate a pre-recorded series of transport times correlated to the second plurality of spaced apart intake points based on a power value of the second fan and a pipe geometry of the second ambient air input network and store the pre-recorded series of transport times as a table in a memory device, wherein the control circuits are configured to activate the second fan to draw in ambient air when smoke aspirated from the first ambient air input network triggers an alarm associated with the ambient condition detector, wherein the control circuits, simultaneously with activation of the second fan, are configured to start the timer to count a transport time between the activation of the second fan and when the smoke aspirated from the second ambient air input network reaches the ambient condition detector, and wherein the control circuits are configured to compare the transport time with the pre-recorded series of transport times stored in the memory device to provide a location of the smoke.
