| 有梁顶棚上探测器设置要求 There is the probe setting requirement on the roof ceiling 在有梁的顶棚上设置点型感烟火灾探测器、感温火灾探测器时，应符合下列规定： When a type smoke detector and heat fire detector is set up on the roof of a beam, the following rules should be met: （1）当梁突出顶棚的高度小于200mm时，可不计梁对探测器保护面积的影响。 (1) when the height of the ceiling is less than 200mm, the influence of the beam on the protection area of the detector is not allowed. （2）当梁突出顶棚的高度为200mm~600mm时，应先确定梁对探测器保护面积的影响和一只探测器能够保护的梁间区域的数量。 (2) when the height of the ceiling is 200mm ~ 600mm, the effect of the beam on the protection area of the detector and the number of girder areas that a detector can protect is determined. （3）当梁突出顶棚的高度超过600mm时，被梁隔断的每个梁间区域应至少设置一只探测器。 (3) at least one detector should be set in each girder area of the beam when the beam protruding from the ceiling above 600mm. （4）当被梁隔断的区域面积超过一只探测器的保护面积时，被隔断的区域应按上文中第（4）款规定计算探测器的设置数量。 (4) when is an area of more than a probe beam partition protection area, the partition area should be according to the above the first paragraph (4) calculating the probe set. （5）当梁间净距小于1m时，可不计梁对探测器保护面积的影响。 When the net distance is less than 1m, the effect of the beam on the protection area of the detector is not allowed. |
