centers or rooms areas where any is too much LZR 1 Laser Detector senses the particles of combustion And provides early warning of fire high sensitivity is balanced with stability to minimize false alarms an ionization detector LZR 1 senses a fast flaming fire Like photoelectric detector it quickly a slow smoldering fire But these detectors the LZR 1 can identify both types of fire early warning performance is to aspiration technology fact independent tests have shown LZR 1 responds as good as better than traditional aspirating without the cost of pipe instal Unlike an aspirating system can pinpoint the location of Faster response and pinpoint can make the difference a minor emergency and a catastrophe laser diode and precision optics make detector super sensitive to smoke much as 100 times more sensitive than standard photoelectric sensor with potential for false alarms might expect such a sensitive smoke to be subject to false alarms so with LZR 1 It uses patented to check for the presence of before alarming The results with solid stability works on the same principle as photoelectric detector When a parti of combustion crosses the light it causes the light to scatter signals the alarm But the differ between an LED beam and a laser is like the difference between a knife and a razor The 100x of this product means heads to the first particle of combustion in itself is not enough to convince to signal an alarm where the patented algorithms into play distinguishing between signals caused by airborne and the first puff of smoke these special algorithms were laser detectors were useful in extremely clean environments longer By selecting the sensitivity the detector in the control panel can protect many environments rapid response and pinpoint are critical

telecommunications computer technology and has fueled a need for early warning Today a major is not to create a major facilities data and computer rooms rooms traffic control centers can be easily shut down even the presence of small amounts of And in some of these environ even a little downtime can a big disaster switching cable and rooms sooner the fire can be detected lower the potential loss That archives and museums where documents and artifacts housed ideal candidates for warning systems technology makes good sense any environment where there a substantial cost of downtime or a investment in installed To cut response time even this technology is best used human interface is available Note The LZR 1 is listed as open area smoke detector As standard guidelines for spacing placement should be followed archives and buildings to avoid smoke fumes water vapor or fog levels of airborne vehicle exhaust or other that cause particles Manuals Online Y S T E M S E N S O R 4 How it Works Principles of Laser Detection Diode Amplifier Receiver Beam principles of laser detection are to those of photoelectric In a photoelectric smoke an LED emits light into a chamber that is designed to out ambient light while allowing to enter Any particles of or dust entering the chamber scatter the light and trigger the sensor LZR 1 works on the same light principle but with 100x sensitivity This ultra sensitivity due to the nature of the laser itself is literally amplified light the is an acronym for by Stimulated Emission Radiation Using an extremely controlled laser diode the laser is transmitted through the to a light trap which elimi any reflection If a particle of or dust enters the chamber from the laser is scattered and the panel using its patented checks the nature of the light to determine whether source is dust or smoke If a of smoke is made the is signaled particles especially those of an early are extremely hence the need for the high of the laser Dust particles the other hand are a different There are two types of dust settled and airborne dust Both affect detector differently some smoke detectors dust can in the darkened chamber Over this dust creates a light colored that gradually increases the of reflected light in the cham making the detector more prone false alarms Since the LZR 1 detec uses a focused beam of laser reflections are minimized in the This means that gradual accumulation is not a problem further minimize the affect airborne dust by discriminating transient signals and real smoke Manuals Online A S E R T E C H N O L

are two smoke sensing in wide use ionization photoelectric Both technologies different strengths Ionization detect fast well are not so quick with slow smol Photoelectric detectors detect fires well but are so quick with fast flaming fires is highly sensitive to both types fire achieves these dual goals of high and high stability by using extremely bright laser diode times brighter than a standard emitting diode coupled with optical amplifier that further the light into the photo This combination allows LZR 1 detect both small and large particles allows it to quickly detect both and slow smoldering order to improve the ability of pho detectors to detect fast flam fires LZR 1 de
