The Notifier FSL-751 VIEW® Laser Detector is a revolutionary
advance in early warning smoke detection technology. The
unique design of this laser detector allows smoke detectionsensitivity that is up to 50 times higher than present photoelectric technology, when combined with enhanced intelligentsensing algorithms in the Notifier AFP-300, AFP-400, NFS-640, NFS2-640, NFS-320, NFS-3030 or NFS2-3030 controlpanels. Because of this high sensitivity, the FSL-751 can provide very early warning of slow smoldering fires. Its performance is comparable to present aspiration technology, at asubstantially lower installed cost.
The FSL-751 uses an extremely bright laser diode, combinedwith special lens and mirror optics (U.S. patent pending), toachieve a signal-to-noise ratio that is much higher than traditional photoelectric sensors. In addition, the tightly focusedlight beam, combined with the intelligent sensing algorithms,allow the system to differentiate between dust and smoke particles. Because of this differentiation, the FSL-751 can be setto extremely high sensitivity, yet can reject false signalscaused by larger airborne particles such as dust, lint, andsmall insects.
The FSL-751 is an intelligent (analog/addressable) detector.Using CLIP mode, up to 99 FSL-751 detectors may beinstalled per loop. On FlashScan® systems (NFS-640/NFS2-640/NFS-320/NFS-3030/NFS2-3030), up to 159 addressesare available. The FSL-751 may be mixed in any combinationwith other Notifier intelligent sensors on the same loop and isquickly installed using the panel autoprogram feature. TheFSL-751 has dual bi-color LEDs, which blink green in normaloperation and illuminate steady red in alarm.
