Very Intelligent Early Warning - Laser Smoke Detector

The Notifier FSL-751 VIEW Laser Detector is a revolutionary advance in early warning smoke detection technology. The unique design of thislaser detector allows smoke detection sensitivity that is up to 50 times higher than present photoelectric technology, when combined with enhanced intelligent sensing algorithms in the Notifier AFP-300, AFP-400, NFS- 640, NFS2-640, NFS-320, NFS-3030 or NFS2-3030 control panels. 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 a substantially lower installed cost.

The FSL-751 uses an extremely bright laser diode,combined with special lens and mirror optics (U.S. patent pending), to achievea signal-to-noise ratio that is much higher than traditional photoelectric sensors. In addition, the tightly focused light 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 set to extremely high sensitivity, yet can reject false signals caused by larger airborne particles such as dust, lint, and small insects.

The FSL-751 is an intelligent (analog/addressable)detector. Using CLIP mode, up to 99 FSL-751 detectors may be installed per loop. On FlashScan® systems (NFS-640/NFS2-640/NFS-320/NFS-3030/NFS2-3030), up to 159 addresses are available. The FSL-751 may be mixed in any combination with other Notifier intelligent sensors on the same loop and is quickly installed using the panel auto program feature. The FSL-751 has dual bi-color LEDs, which blink green in normal operation and illuminate steady red in alarm.
