Please ask the master ruler about the number of temperature sensors in the garage.
Reply 5# consulted Shanghai Fire Bureau and Building 5 # of LINA 008, which is correct. There is something wrong with the statement that the scale in Building 2 is short. Please correct as follows: For example, the landlord-1) When the beam height exceeds 600mm, the "area (m2) of S- detection area" shall be calculated according to the area enclosed by the center line of the beam. That is, when the beam height exceeds 600mm, the "S- detection area (m2)" in the above example is 2 1m2. One temperature detector with a protection area of 20m2 requires two temperature detectors. 2) When the beam height is less than 200mm, the influence of the beam on the detector protection zone can be ignored. In other words, the underground garage is calculated according to the whole area to be protected. 3) When the height of the beam protruding from the ceiling is 200~600mm: "The influence of the beam on the detector protection area and the number of inter-beam areas that the detector can protect shall be determined according to Appendix B and Appendix C of this specification." The area between beams of the beam partition Q- When the height of the beam protruding from the ceiling is 200~600mm, for example, the area surrounded by the center line of the beams around is also 2 1m2. Both the beam height and the room height will affect the fire detector, but both the smoke detector and the temperature detector should completely cover the detection area to ensure safety.
