One-on-one vs. Multi-emitter Challenge to beams: Beams unable to provide angular coverage Customer Impact: Additional fire protection required for unprotected areas outside the beams coverage. Increase in installation and maintenance costs OSID: Extra coverage can be provided through low cost emitters and angular beam design. Applications: Special design features (architectural designs, acoustic requirements) Atriums, stadiums, atria, auditoriums, concert halls, amphitheatres, terminals, etc. Non-rectangular Shaped Ceilings 3 beam detectors can be replaced by a single Imager and 3 Emitters 2 beam detectors can be replaced by single Imager and 2 Emitters Beam detector coverageOSID coverage Non-rectangular Shaped Ceilings Place the imager(s) in the most appropriate corner with regard to geometry and minimum wiring.

Confidential Information13 Installation & Spacing Include no obstructions between the Emitter and Imager Allow for a 20 cm x 20 cm (8 x 8) free view in line of sight Ensure the system is mounted well above the head height of a person Mount both imager and emitter on solid parts of the building such as the main support structure Avoid direct sunlight into the imager unit. If direct sunlight cannot be avoided, place imager higher than the emitters to force the imager to look below the horizon. Avoid the imager facing the rising and setting sun, install North-South. Consider effects like stratification and other parameters that may affect the performance of the detector (e.g. room geometry, ceiling height, ceiling shape, ) Positioning STRATIFICATION The effect which occurs when smoke, which is hotter than the surrounding air, rises until equal to the temperature of the surrounding air, causing the smoke to stop rising. This typically happens in atria covered with windows where the air is heated by the sun Adding extra emitters at lower level will result in a faster detection of smoke Stratification Detection grid Using 2 sets of OSID create a grid that allows for early and cost-effective detection at all levels of the atrium, at ground level as well as at the top level. The grid uses OSIDs horizontal and vertical spatial performance to crate a full coverage with minimum wiring costs Stratification Detection Grid Comparison of Code of Practice documents CountryDocumentLimits of ceiling height UKBS 58391:2002Maximum ceiling height: General (life protection):beam= 25m. Category P systems (automatic fire detection systems intended for the protection of property) and 5 minute fire service attendance: beam= 40m, GermanyVdS 2095:2005Beam= 16m, provision of a second monitoring level is recommended at room heights exceeding 12m.NetherlandsNEN 2535:2007General: beam= 7.5m.For 7.5m-16m a "second layer" of beam detection is required. The use of beams between 16m and 25m is "Not suitable unless it is demonstrated with a fitness test fire. FranceR7 Rules (2006)When the height of the space exceeds 12 m, two levels of detection placed at heights wisely determined, must be provided. DenmarkRev.AF232 (2008)Up to 11m may be used "but special measures need to be taken to counter false alarms". For heights greater than 11 m beam detector may be used but several detectors are required at different heights with a maximum 11 m between levels. Beams can be used at heights oreater than 25m. USANFPA 72 (2007)There appears to be no limit for beams. Most relevant statement is from 8.3.2.3.5: "The procecures presented in this section are based on I analysis of data for ceiling heights up to 9.1 m (30 ft). No data were analyzed for ceiling heights greater than 9.1 m (30ft). In spaces where the ceiling heights exceed this limit, this section offers no guIdance." ChinaGB 50116-98Maximum beam height: 20 m Typical Heights for Beam Detectors The Emitters need to be located and spaced according to local codes and standards (BS5839.1, NEN2535, NFPA72, AS1670.1, GB50166, )to provide full coverage of the protected space For multiple heights of protection, make sure that the areas at the emitters are compliant.
