JABLOTRON ALARMS a.s.Pod Skalkou 4567/33 46601 Jablonec n. NisouCzech Republic www.jablotron.com| ||The JA-110ST Bus combined smoke and heat detectorThe JA-110ST Bus combined smoke and heat detector 1 / 2 MLW51612The JA-110ST is a component of the JABLOTRON JA-100 system.It is used to detect fire hazards in a building interior. The product is notdesigned to be installed outdoors or in industrial premises.The JA-110ST consists of an optical smoke detector and a heatdetector. The optical smoke detector is very sensitive to large dustparticles which are present in dense smoke. It is less sensitive tosmaller particles generated by the combustion of liquids such asalcohol. That is why the fire detector also contains a built-in heatdetector which has a slower reaction but is much better at detecting firewhich generates only a small amount of smoke. The detector hasa status reaction (reports its activation and deactivation). The detectorshould be installed by a trained technician with a valid certificate issuedby an authorized distributor.Detector locationThe smoke detector must be installed so that any smoke easily driftsinto the detector owing to natural thermal circulation (usually on theceiling). The detector can only be used in enclosed interiors. It is notsuitable for interiors where smoke can disperse over a large area andcool down (e.g. interiors with extremely high ceilings – above 5 m) – thesmoke would not reach the detector position.The detector must always be placed in the section leading to the exitof the building (escape route), see Figure 1. If the building has a floorarea greater than 150 m2, installation of an additional detector in someother suitable place is required, see Fig.2.123 451. kitchen,2. living room,3. – 6. bedroomsy /basiccoverage{recommendedcoverageFig 1123 456Fig 21236Fig 3In buildings and family houses with multiple floors, detectorsshould be installed above stairwells. It is recommended to placeadditional detectors in rooms where people sleep. See fig 3.Installation on level ceilingsPlace the detector in the center of the room if possible. The detectormust not be recessed into the ceiling due to the possible existenceof a warm air layer on the ceiling. Never place the detector in thecorner of the room (always keep at least a 0.5 m distance from thecorner) see Fig 4. There is an insufficient circulation of air in corners.Installation on sloping ceilingsIf the ceiling is not suitable for mounting on a level surface (e.g.a room under a roof ridge), the detector can be installed as in Fig. 5.0.5mTOPFig 40,9 mFig 5centre of the room, best locationacceptable locationWalls, partitions, barriers and lattice ceilingsThe JA-110ST detector must not be installed closer than 0.5 mfrom any wall or partition. A narrow space with a width of less than1.2 m requires the detectors to be placed at a distance of at least onethird of its width away. In a case when a room is separated intosections with furniture, racks or semi partition walls, which do not reachthe ceiling, the space is considered to be fully separated if the gapbetween the top of these and the ceiling does not exceed 0.3 m.A free space of at least 0.5 m is required under and around thedetector. Any irregularities of the ceiling (e.g. girders) exceeding 5 % ofthe ceiling height should be considered a wall and the above-mentioned limitations should apply.Ventilation and air circulationThe detectors must not be installed directly by ventilation or airconditioning vents, etc. If the air is supplied through a perforatedceiling, there must be no perforation within a radius of 0.6 m of thedetector.Avoid installing the detector in the following locations: Places with poor air circulation (niches, corners, apexes ofA-shaped roofs, etc.) Places exposed to dust, cigarette smoke or steam Places with over-intense air circulation (close to ventilators, heatsources, air conditioning outlets, etc.) In kitchens and other cooking places (because steam, smoke oroily fumes can cause false alarms or reduce detection faults). In areas with lots of small insectsWarning: The most false alarms are caused by animproper location of the detector.See CEN/TS 54-14 standards for detailed installation guidelines.InstallationAbide by the procedures recommended in the previous paragraphs.1 23BUS1400- 00- 0000- 0001546+ -Fig 6: 1 – detector cover opening (removal); 2 – detector cover closing(insertion); 3 – optical signaling; 4 – arrow showing where to insert thedetector onto the bottom part; 5 – bus connection terminals;6 – production codeInstructions1.
