System Sensor’s Aspiration System Earns High Marks for Nuisance Rejection
ST. CHARLES, Ill. — System Sensor announces its FAAST aspirated smoke detection system fared better in difficult environmental conditions compared to a similar competing system, based on test trials conducted by a third-party engineering consulting firm.
Naperville, Ill.-based Packer Engineering Inc. conducted experiments on the FAAST system and one other aspirated smoke detection system under three test conditions: smoke, dust, and both smoke and dust.
Both systems alarmed with the presence of smoke, while differentiation between the two products came with the tests involving dust. Among the test findings, the competing system would falsely alarm with the presence of dust, and in most cases, FAAST would not. The aspiration systems responded differently when smoke was then introduced; FAAST would alarm, whereas the competing system had already false alarmed for dust and remained on alarm.
The testing, which was conducted by Packer at the Univ. of Maryland’s Fire Testing and Evaluation Center, indicates the FAAST system has a higher capability to discriminate against nuisance sources and thereby has fewer nuisance alarms compared to the competing system.
