The research revealed that a manual detector, used as a standby item in the system of thermal and smoke fire detectors, makes it possible to reduce the failure rate of the system and increase the average time of failure-free operation. | |
24 Jun 2021 | It offers a robust, straightforward approach to detect faults, and can measure and compensate for drift across the entire smoke detector system. |
09 Jul 2010 15 Citations | In its completion and entirety, the smoke detector unit properly functions and in the manner it was originally planned and designed. |
10 Citations | The SDAA was found to be very accurate in determining detector activation times for both high- and low-velocity smoke flows. |
10 Citations | It was determined that FDS can predict smoke detector activation when used in conjunction with smoke detector lag correlations that correct for the time delay associated with smoke having to penetrate the detector housing. |
29 Citations | With simple mechanical structure and high accuracy, this sensor improves the performance of optical fire smoke detector with high sensitivity, low-cost and unique ability to resist the false alarms caused by non-fire aerosols. |
12 Citations | The exclusive use of the time domain analysis in the design tuning to lower the probability of false alarms is caused by the output signal binary nature prevailing in the optical smoke detector designs. |
Determination of the presence of an operational smoke detector in 1- and 2-family dwellings may be a useful injury prevention act during such EMS calls. | |
01 Oct 2017 | Experimental results show that the proposed smoke detection algorithm performs well than the conventional smoke detection algorithms in terms of accuracy of smoke detection. |
15 Citations | This paper introduces a novel new smoke detector characterized by its very small size and very high sensitivity. |
89 Citations | It is, therefore, recommended that smoke detector alarms be installed in the bedrooms themselves such that the signal intensity is at the maximum level tolerable to the human ear, that is approximately 90 dBA. |
They can be installed by a homeowner just as they would a normal smoke detector. | |
25 Citations | The data showed that there was a large amount of variability in the measured smoke optical density values outside a detector at the time of alarm. |
29 Citations | It is shown that such a smoke detector is able to operate reliably under low concentration of smoke and high relative humidity conditions. |
The results of these experiments show that the smoke detectors, especially the ionization detector, are sensitive to cooking fumes and nuisance alarms are easy to happen. | |
101 Citations | Alarm algorithms utilizing ionization detector smoke measurements proved to be more effective than measurements from photoelectric detectors. |
24 Jun 2021 | By conducting tests with live smoke, we show that both FallTime and DriftTestButton perform more effectively than existing fault tolerance techniques and stand to substantially reduce the risk that a smoke detector fails to alarm in the presence of smoke. |
