Notifier LPX-751L VIEW® LASER Smoke Detector for the AFP-200, AFP1010, and AM2020

March 24 2005 H 115 LASER Smoke Detector the AFP 200 AFP1010 and AM2020 Intelligent Addressable Devices Vol 27 Fire Fire Marshal 2107 NOTIFIER LPX 751L VIEW Laser Detectors provide a revo advance in early warning smoke detection technology unique design of these detectors allows smoke detection that is 10 to 50 times higher than present photoelectric Because of this high sensitivity the LPX 751L can very early warning of slow smoldering fires Its perfor is comparable to present aspiration technology at a sub lower installed cost LPX 751L uses an extremely bright laser diode combined special lens and mirror optics to achieve a signal to noise that is much higher than traditional photoelectric sensors addition the tightly focused light beam allows the system to between dust and smoke particles Because of differentiation the LPX 751L can be set to extremely high yet can reject false signals caused by larger airborne such as dust lint and small insects LPX 751L is an intelligent analog addressable detector and up to 99 LPX 751L detectors installed per AFP 200 or AM2020 loop It may be mixed in any combination other intelligent sensors on the same loop and is quickly in using the panel autoprogram feature VIEW system provides drift compensation meeting UL as a calibrated sensitivity meter maintenance selection of three alarm levels and drift compensation Very Intelligent Early Warning VIEW smoke detection Advanced laser light source and patented optical design Sleek low profile housing 1.66 42.164 mm height Analog addressable communications protocol provides ex reliable operation Sensitivity to 0.03 foot Low standby current allows 99 devices per two wire loop in to 99 modules Rotary decade switches allow quick selection of address resorting to binary switches special programmers bar coding devices Dual LED design provides 360 viewing angle Two LEDs blink red for normal steady red for alarm Built in magnetic test switch or automatic test commanded

photo sensor The light then passes into a light trap and is absorbed The photo sensor is activated by a of smoke particles in this small volume light beam a typical photoelectric detector the light beam is very wide and can reflect off the chamber walls into the photo sensor dust accumulation changes the wall color from flat black to gray With the LPX 751L the concentrated light beam does touch the walls therefore it is much less susceptible to dust accumulation scatters light in all directions and in a typical photoelectric detector only a small portion of that scattered light reaches photo sensor itself In the LPX 751L a special mirror reflects and concentrates most of the scattered light into the photo See laser detail drawings on this page to smoke airborne dust particles are very large and very sparse Since a they are in motion b the illuminated is very small and c the LPX 751L flashes the laser only every few seconds then the occasional dust particle cannot in the light volume for more than one or two samples This transient signal from dust is the key to the dust discrimination by VIEW DIODE LENS LED DIRECTION CHAMBER SHIELD COVER SCREEN BOARD DIODE BEAM TRAP Detail
