FSL-751 Very Intelligent Early Warning Laser Smoke Detector
 |
|
| |
The Notifier FSL-751 VIEW® Laser Detector provides a revolutionary advance in early warning smoke detection technology. The unique design of this detector, combined with enhanced intelligent sensing algorithms in the Notifier AFP-300, AFP-400, NFS-640, NFS-3030 or NFS2-3030 control panels, allows smoke detection sensitivity that is up to 50 times higher than present photoelectric technology. 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 achieve a 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 .
