VG-6688 Reflective Beam Smoke Detector
VG-6688 Reflective Beam Smoke Detector is designed as a single unit incorporating an infra-red tansmitter and receiver. The signal generated in the transmitter element and reflected by the prism back to the receiver element is analyzed for the presence of smoke. When smoke particles enter the area between the unit and the reflector, obscuring the infra-red light and then cause a reduction in the signal. When the smoke level reaches the predetermined threshold, an fire is detected and alarm is activated.VG-6688 Beam Detector can steer a laser onto the installation point of prism reflector. Then adjusting the vertical and horizontal knobs to the optics, as well as alignment indicator, make everything can be done by one person easily and simply. Moreover, VG-6688 is developed with a unique algorithm to self-adapt to the distance between the unit and relfector without any physical setting. Last but not least, the detector has three sensitivity levels settable for particular need of different
applications.
VG-6688 Beam Detector effectively monitors largeareasspanning up to 100 meters in commercial andindustrialapplications, making it an excellent choice for applicationswithhigh ceilings and large spaces, such as Warehouses, LeisureCentres, Shopping Centres, Cinemas, Museums, HotelsandCathedrals or Historical Buildings. Due to itsseamlessintegration to V-Great systems, the detector guaranteesreliable performance.
