per NFPA 25 NFPA 72 instance the signals from the detector are monitored and processed via the algorithm technology which the signals into a neural network to an intelligent multi criteria addressable Infrastructure Building Products OOH941 Fire Detector ASAtechnology Data Sheet 9904 usa siemens com fire Heat Receiver Backward Forward Labyrinth OOH941 Light Scattering Technology Overview continued encompassing result is an intelligent detector that provides enhanced detection capability to a wide range of of combustion while offering unsurpassed rejection to nuisance alarm sources including dust steam cooking aerosols and other deceptive phenomena that could cause false alarms It is known at Siemens as the guarantee Model OOH941 is a two wire addressable device functioning as a multi purpose detector satisfying the revised of UL 268 7th edition using smoke and heat detection in a singular aesthetically pleasing package to other multi functional detectors Model OOH941 also serves as a very cost effective viable detection that saves on product installation maintenance costs The unit value is multiplied with built in the True Class X NFPA 72 compliant SLC isolation feature supporting up to 252 isolation ready devices loop When used in mixed mode a maximum of 30 non isolated devices between isolation devices wired in polarity mode Each detector fits into one 1 wall or ceiling footprint and only occupies one 1 address on the circuit SLC patented forward and backward light scattering technology which is able to distinguish both small and large of combustion operates at the core of each Model OOH941 intelligent addressable detector Each Model detector provides an eco friendly solution to legacy ionization detectors eliminating the need for a radioactive along with inevitable HAZMAT disposal requirements Therefore each detector is capable of detecting both and flaming fire all in ecologically efficient manner and is a valid RoHS compliant Restriction of Substances detection alternative to legacy ionization detectors 2 thermal sensors make each Model OOH941 detector a robust reliable device suitable for the most challenging Additionally Model OOH941 works as a heat detector compliant with NFPA 72 and UL 521 Operation Light Scattering Technology high quality optical electronic measuring chamber for each Model OOH941 houses the following components 2 optical transmitters 1 optical receiver 2 thermal sensors transmitters illuminate the smoke particles from different angles one sensor creates forward scatter and the other creates backward scatter The scattered light subsequently reaches the receiver photodiode and generates a electric signal The combination of a forward and backward scatter facilitates optimum detection as well differentiates between light and dark particles particle size type of detection creates standardized responsive behavior therefore optimizing the differentiation between signals and deceptive phenomena Additionally the heat sensors make it possible to detect fires without smoke this scenario generates the following advantages Early detection of all fire types of fire whether they generate light or dark smoke or no smoke The fire detector can be operated at a lower sensitivity level thus achieving a higher immunity against false alarms may otherwise be caused by cold aerosols e g by smoking electrical welding etc the case of an open fire the smoke sensitivity is heightened by a temperature increase which means that a level that is comparable to a wide spectrum smoke detector can be achieved and maintained
