常閉防火門需要防火門監控嗎

发布日期: 2025-06-30 訪問量：13243

常闭式防火门因其平时处于关闭状态，能够更大程度地发挥防火分隔作用。豐台防火門監控系統是一種用于監測和控制建築內防火門狀態的系統，避免出現無法實現防火分隔的功能。

《建筑防火设计规范GB50016-2014》 “6.5.1 防火门的设置应符合下列规定：

（1）設置在建築內經常有人通行出的防火門宜采用常開防火門。常開防火門應能在火災時自行關閉，並應有信號反饋功能。

（2）除允許設置常開防火門的位置，其他位置的防火門都采用常閉防火門，常閉防火門應在其明顯位置設置“保持防火門關閉“等提示標識。

（3）除管井檢修門和住宅的戶門外，防火門應具有自行關閉功能┅┅“。

标准说的是常开的防火门是需要监控的，但是对常闭式防火门并没有要求。

《豐台火災自動報警系統设计规范GB50116-2013》 “4.6.1 防火门系统的联动控制设计，应符合下列规定：

（1）應由常開防火門所在防火分區內的兩只獨立的火災探測器或一只火災探酬器與一只于動火災報警按鈕的報警信號，作爲常開防火門關閉的聯動觸發信號，聯動觸發信號應由火災報警控制器或消防聯動控制器發出，並應由消防聯動控制器或防火門監控器聯動控制防火門關閉。

（2）疏散通道上各防火門的開啓、關閉及故障狀態信號應反饋至防火門監控器”。兩個標准的要求並不是完全一致。

一些大型商场、超市、医院、学校等人员密集场所的疏散通道上，为了保证人员通行的便利性和疏散的顺畅性，通常会设置常开式防火门。在高层建筑疏散楼梯入口处等位置，常设置常闭式防火门，平时和火灾时都呈关闭状态，推开后能自动关闭。

Mary said she would be satisfied with a shawl and a fan and anything else that was pretty. The countries might stay where they were, and there were doubtless a good many things in them that nobody would want anyway. All she wished was to have anything that was nice and pretty. Here is Frank's account of the wrestling as it appeared in the next letter he sent home: CHAPTER FOUR "What, the diamonds that have caused all this trouble to get. Never!" if one had perfect confidence in the probity of one's instructor. The report he got was that the amphibian was still flying. The scene grew every day more busy as the queen became more obviously failing. Harley, at Hanover, was plying the Elector and his family with reasons why the prince ought not to go to England. The Elector himself appeared quite of the same opinion; but not so the Electress or her son. The Electress, who was now nearly eighty-four, and who was undoubtedly a woman of a very superior character, still had that trace of earthly ambition in her, that she used frequently to say she should die contented if she could only once for a little while feel the crown of England on her head. She was the youngest daughter of Elizabeth of Bohemia, who had ruined her husband by a similar longing after a far less resplendent diadem. When pressed by Harley, the Electress and her son presented him with a memorial, which he was desired to forward to the queen. Anne, in indignation, addressed a letter to the Electress, but without effect; and on the 30th of May she indited a more determined epistle to the Elector himself:—"As the rumour increases that my cousin, the Electoral Prince, has resolved to come over to settle in my lifetime in my dominions, I do not choose to delay a moment to write to you about this, and to communicate to you my sentiments upon a subject of this importance. I then freely own to you that I cannot imagine that a prince who possesses the knowledge and penetration of your Electoral Highness can ever contribute to such an attempt, and that I believe you are too just to allow that any infringement shall be made on my sovereignty which you would not choose should be made on your own. I am firmly persuaded that you would not suffer the smallest diminution of your authority. I am no less delicate in that respect; and I am determined to oppose a project so contrary to my royal authority, however fatal the consequences may be." In preparation for this movement James the Pretender was to sail secretly to Spain, in readiness to cross to England; and he had already quitted his house in Rome and removed to a villa, the more unobserved to steal away at the appointed moment. Ormonde also had left Madrid and gone to a country seat half way to Bilbao, when the secret of the impending expedition was suddenly revealed by the French Government to that of England. The conspirators had been mad enough to apply to the Regent for five thousand troops, trusting that, notwithstanding his peaceful relations with Britain, he would secretly enjoy creating it some embarrassment. But in this, as in all other views, they proved more sanguine than profound. Sir Luke Schaub, the British Ambassador, was immediately informed of it on condition, it was said, that no one should die for it. [65] As has been before remarked, when Deacon Klegg made up his mind something had to happen. It was now quite dark. He took one of the $5 bills out of his breast pocket and put it in a pocket where it would be handy. He looked over at the house, and saw the old man and woman sitting by the fire smoking. He picked up the hickory withe to keep off the dogs, and made a circuit to reach the chicken-coop from the rear of the house. The dogs were quarreling and snarling over their supper, and paid no attention to him, until he had reached the coop, when they came at him full tilt. "There is nothing for me to do," she said, and her eye closed. "No. I wait for you, but only to tell you this: there is nothing I can do." "He's safe enough now—we may as well go and have a look round." "Handshut!" At the distance of nearly a mile from Sudley Castle, and at about a quarter of a mile from the high road that led to Oxford, was a singular kind of quarry or cliff. Its elevation was considerable, and the portion of the hill visible from the road was covered with the heathy verdure which usually springs from such scanty soil; but on passing round to the other side, all the barren unsightly appearance of a half worked quarry presented itself. Huge masses of stone stood firmly as nature had formed them, while others, of a magnitude sufficient to awaken in the hardiest, a sense of danger, hung apparently by so slight a tenure, that a passing gust of wind, seemed only required to release their fragile hold. But the hill had stood thus unaltered during the remembrance of the oldest inhabitant of Winchcombe. Strange stories were whispered respecting this cliff, but as the honour of the house of Sudley, and that of another family equally noble, were concerned in the tale, little more than obscure hints were suffered to escape.
