Standard for Installation of Fire Safety Devices based on Use and Occupancy Article 189
Smoke exhaust equipment located in the vestibules of special refuge stairways and the emergency elevators shall meet the following requirements:1. Where windows directly face outdoors, the following requirements shall be met:(1)The part of a window, which contacts the fumes during smoke exhaust, shall be made of incombustible materials.(2)The effective opening of the window shall be located above halfway of the ceiling height.(3)The effective opening area of the window shall be more than 2m2. Where the special refuge stairways shares a same vestibule with the emergency elevator (hereinafter referred to as “sharing duty”), the area shall be more than 3m2.(4)The window set forth in the preceding item, which is kept closed at all times, shall be equipped with a manual station that shall be installed on a wall around 80 cm to 150 cm from the floor. Easy-to-follow operating instructions shall be posted near the station.2. Smoke exhaust and supply air duct installation shall comply with the following requirements:(1)The smoke exhaust vents, smoke exhaust ducts, supply air intakes, supply air ducts, and other parts of the smoke exhaust equipment exposed to direct contact with the smoke shall have an incombustible material construction.(2)Where the smoke exhaust ducts or supply air ducts cut across a fire compartment, a fire damper shall be installed on the intersection. The construction of the intersection juncture where the duct crosses the fire compartment shall be fire resistance rated as that of the fire compartment. Where duct passes through other floor levels, the vertical duct shall be installed at the fire compartmented shaft. Where the exhaust duct has fire resistance performance, approved by the central regulating authority, and the construction of the intersection juncture where the duct crosses the fire compartment is fire resistance rated as that of the fire compartment, the foregoing requirement shall not apply.(3)The smoke exhaust vent shall be positioned at a height at least halfway up to the ceiling or higher and be connected to the smoke exhaust ducts directly linked to the outside, and said ducts shall be connected to smoke exhaust fans. The supply air intake shall be located at a height lower than halfway up to the ceiling, and said intake shall face outdoors, and have an area of at least 1 m2 (where intakes are used for shared duty, the area shall be at least 1.5 m2); or the intakes shall be connected to the supply air ducts directly linked to the outdoor, and be connected to the supply air fans.(4)The smoke exhaust capacity of smoke exhaust fans, and supply air capacity of supply air fans, shall be at least 4 m3/sec. ( 6 m3/sec for fans used for shared duty) and shall be automatically activated upon the opening of the smoke exhaust vent and supply air intake.(5)The supply air intakes and smoke exhaust vents shall be equipped with manual stations prescribed in Item 4 of the preceding Subparagraph, and detector activated automatic operating devices, and be kept closed under normal circumstances, unless being activated through the aforesaid stations and devices, or the remote operating devices. The construction of the vent blades shall allow the vents to remain open and unaffected by the surge of smoke current after the vents are opened.(6)The smoke exhaust vent, supply air intake, smoke exhaust fan, and supply air fan shall be connected to the emergency power source, and power source capacity shall be enough to run the system effectively for a period of at least 30 minutes.
中文原文 各類場所消防安全設備設置標準第189條
特別安全梯或緊急昇降機間排煙室之排煙設備，依下列規定選擇設置：
一、設置直接面向戶外之窗戶時，應符合下列規定：
（一）在排煙時窗戶與煙接觸部分使用不燃材料。
（二）窗戶有效開口面積位於天花板高度二分之一以上之範圍內。
（三）窗戶之有效開口面積在二平方公尺以上。
但特別安全梯排煙室與緊急昇降機間兼用時（以下簡稱兼用），應在三平方公尺以上。
（四）前目平時關閉之窗戶設手動開關裝置，其操作部分設於距離樓地板面八十公分以上一百五十公分以下之牆面，並標示簡易之操作方式。
二、設置排煙、進風風管時，應符合下列規定：
（一）排煙設備之排煙口、排煙風管、進風口、進風風管及其他與煙接觸部分應使用不燃材料。
（二）排煙、進風風管貫穿防火區劃時，應在貫穿處設防火閘門；該風管與貫穿部位合成之構造應具所貫穿構造之防火時效；其跨樓層設置時，立管應置於防火區劃之管道間。
但設置之風管具防火性能並經中央主管機關認可，該風管與貫穿部位合成之構造具所貫穿構造之防火時效者，不在此限。
（三）排煙口位於天花板高度二分之一以上之範圍內，與直接連通戶外之排煙風管連接，該風管並連接排煙機。
進風口位於天花板高度二分之一以下之範圍內；其直接面向戶外，開口面積在一平方公尺（兼用時，為一點五平方公尺）以上；或與直接連通戶外之進風風管連接，該風管並連接進風機。
（四）排煙機、進風機之排煙量、進風量在每秒四立方公尺（兼用時，每秒六立方公尺）以上，且可隨排煙口、進風口開啟而自動啟動。
（五）進風口、排煙口依前款第四目設手動開關裝置及探測器連動自動開關裝置；除以該等裝置或遠隔操作開關裝置開啟外，平時保持關閉狀態，開口葉片之構造應不受開啟時所生氣流之影響而關閉。
（六）排煙口、進風口、排煙機及進風機連接緊急電源，其供電容量應供其有效動作三十分鐘以上。
