VLP-002 Type:? fire detector alarm sounds:? a detailed description of the sound and light VLP-012 very early aspirated air sampling smoke detectors: one, VLP-002 Overview: VLP-012 Xtralis VESDA smoke detector is a series of products to detect the core component. Using its unique detection principle, the detector sensitivity range VLP up 0.005 - 20% obs / m (0.0015 - 6.25% obs / ft). VLP detectors are "very early smoke detection and alarm equipment", which can be detected at a very early stage of a fire, the smoke from a trace to a high concentration of smoke, which are able to provide reliable detection. How does it work? Efficient aspirator air samples collected, transferred to VLP detector through the air sampling pipe network. Each intake manifold has a flow sensor to monitor the airflow changes in the sampling tube. VLP detector exhaust air sampling, and sampling the air may be vented back into the protected area. In the VLP detectors, sampling the air is transferred to the laser detection chamber. Finely filtered clean air to protect the optics from contamination detection chamber. Detection chamber using a stabilized laser source and sensors installed fine, you can make the best response to a wide range of smoke types. Status of the detector, all alarms, service and fault events, are transmitted to the monitor via VESDAnet and external systems. AutoLearn? (Self-learning) VLP detection technology uses a unique software tool that can ensure the operational status of the system to achieve the best in a variety of different environments. AutoLearn? (Self-learning) function can be monitored on the environment, sets the most appropriate alarm thresholds (Alert, Action, Fire 1 and Fire 2) during debugging, and thus the potential of fires very early detection and alarm, while avoiding false reported. Reference detector (Referencing) adopted under the "supply of fresh air" function, the use of air handling systems in a controlled environment may be affected by external contamination. Reference detector feature ensures external contamination will not be detected in the protected area's concentration on smog. The system can effectively exclude infrequent events, sustained and stable operation, to avoid false positives. Performance characteristics? Extremely wide sensitivity range?
