摘要
An aspirated detecting system includes a multi-channel aspirated smoke detector with each channel including an air moving element, such as a fan, first and second sets of substantially identical air flow pipes where each set defines a plurality of spaced apart inflow ports. Control circuits activate a first element and then a second element to establish a transport time associated with at least one inflow port in response to the detector sensing a predetermined smoke condition. The control circuits include a storage unit which includes pre-stored timer values which are associated with respective transport times from an associated inflow port.
