Summary: Because the fire of fire control respect calls the police automatically,reach linkage system, branch of fire control director does not allow to bring into its Lou Yu to accuse oneself come in the system, accordingly, can regard an independent system as its only. This project builds use close already time of a year, the bigger orgnaization of a few abroad already handled official bussiness inside, from the point of use effect, it is satisfactory, each system moves to all achieve the requirement of the design.

, system of the ground connection that prevent thunder
This project was used as a result of the foundation pile and turn pattern greatly, accordingly, and before configuration differs somewhat. Stake grows to be controlled in 12 meters, although big motherboard took waterproof step, but every picket was not done waterproof, consequently, use picket radical to make ground connection. Not was outdoor hit ground connection pole technically. Of housetop prevent Lei Yin to get offline, still press normative demand, use stake inside two advocate muscle, long solder, be in picket radical place to become state of set prescription case. Housetop periphery is set avoid thunder is taken. Because this building is standing by 3 annulus at the same time a ∮ is set on the top the stainless steel canal of 500, regard architectural as adornment, and the roofing of topmost tower above of steel tube is highest be in nearly 20 meters, to this outstanding metal object, on one hand with housetop avoid thunder belt is linked together, on the other hand, in the coping of this steel tube, added the lightning rod of French Yi Lida. Look from the ground, as a result of the headroom in more than 100 meters, did not affect architectural to decorate the effect, in the meantime, rose to prevent the effect of thunder again. Undertaking preventing side direction be struck by lightning, in the process that makes grading ring, also undertook assorted carefully with contractor of vitreous act wall. The frame as a result of installation glass act and bury beforehand in join process, add the gasket that has insulation, accordingly, requirement contractor is built in what designation position undertakes both sides receive, form good ohmic contact, can use its frame to serve as grading ring thereby. From resistor of ground connection of the actual measurement after whole structure is finished, it is under 1 ohm, strong weak report is operable in satisfying a standard ground connection pole, resistor of requirement ground connection is less than or be equal to the requirement of 1 ohm. Build from the building so far, also encounter the thunderstorm weather of Beijing, all did not produce any problems.
2, fire calls the police automatically reach linkage control system
In this project, adoption fire calls the police automatically the IFC-2020 system that the system is American Jiang Sen company, this system is system of analogy of a whole intelligence, collect calls the police reach linkage at a suit, but according to different environment, centrally calls the police control dish go up to have sensitivity set to each detector, can reflect its concentration, and have any change when the environment, control calls the police in the center of dish can make compensation automatically to the sensitivity of detector.
