VLC is using Xtralis VESDA VLP detectors proven effective detection techniques, while a modified aspirator design, and the combination of these elements closely, assembled in a small enclosure, and is equipped with a simple display device. VLC is available in two versions, one can only connect (RO relay) through the relay, and the other can be connected to the network via a relay or VESDAnet (VN network type). VN version should use a remote display module, the current status of the detector can be transmitted to the most favorable position. Remote Display Module has 7 remote relays, signaling support for all applications that might be required. VN version allows several detectors on VESDAnet, so that it can put one of these detectors as another reference detector detectors. VLC is composed of two parts: the host and the front panel. All the key components of the host shell wearing parts to accommodate all of the detector, the main processor board and detector chamber are mounted away from the general access area, so that you can protect them from damage during installation and maintenance. The front panel includes: five LED indicators: Fire (fire), Pre-Alarm / Alert (warning / alarm), Fault (fault), OK (normal), Reset / Isolate (Reset / isolation). (Reset / Isolate (Reset / isolation) button (press the "Reset", press and hold the "isolation")) Efficient aspirator air samples collected continuously transmitted to the central detector through the sampling pipe network. The samples were air flow sensor into the device, and then through two filters (most of the air will be discharged into the protected area detector). Air samples were filtered to remove dust and the first level of impurities, and then into the detection chamber for smoke detection. The resulting clean air after the second-stage fine filter, providing a protective barrier, so that the optical surfaces from contamination detection chamber. The detection chamber uses a stable and efficient laser source and unique sensor structure that can make the best response to the many types of smoke. When the smoke through the detection chamber, extremely sensitive sensor circuit will detect smoke caused by light scattering signal. Can with the time and date stamps detector status and all alarms, service and fault events are monitored and logged. Can be connected through advanced VESDAnet communications network transmission status report (only VN version) by a simple relay. VLC-505 performance characteristics? Absolute value detect smoke?
