signal at 40 4.4 sprinkler systems 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 OOHC941 Fire CO Detector ASAtechnology Data Sheet 9903 usa siemens com fire Heat OOHC941 Receiver Backward Forward Labyrinth CO sensor Light Scattering Technology with CO sensor 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 and other deceptive phenomena that could cause false alarms It is known at Siemens as the guarantee OOHC941 is a two wire addressable device functioning as a multi purpose detector satisfying the revised of UL 268 7th edition using smoke heat and CO gas detection in a singular aesthetically pleasing package to other multi functional detectors Model OOHC941 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 signal circuit SLC patented forward and backward light scattering technology which is able to distinguish both small and large products combustion operates at the core of each Model OOHC941 intelligent addressable CO with ASA 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 The powerful ASAtechnology enables simultaneous of both smoldering and flaming fires all in ecologically efficient manner and is a valid RoHS compliant of Hazardous Substances detection alternative to legacy ionization detectors 2 thermal sensors as well as an electromechanical CO sensor are included making each Model OOHC941 a robust reliable device suitable for the most challenging applications Additionally Model OOHC941 works as a carbon monoxide CO life safety gas detector compliant with NFPA 72 and UL2075 Light Scattering Technology high quality optical electronic measuring chamber for each Model OOHC941 houses the following components 2 optical transmitters 1 optical receiver 2 thermal sensors 1 CO sensor 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 as 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 CO sensor enables faster detection of fires with incomplete combustion as well as fires with the development of high of CO The combination of optical thermal and CO signals optimizes detection reliability 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 a detection reliability level is comparable to a wide spectrum smoke detector that can be achieved and maintained
