Standard for Installation of Fire Safety Devices based on Use and Occupancy Article 144
Wiring of automatic fire alarm equipments for gas leakage shall comply with Regulations for Installation of User's Electricity Device.1.500V DC insulation ohmmeter shall be used to measure the insulation resistance between the wires of power circuit as well as between the wire and the earth. Where the voltage to earth is not more than 150V, the resistance shall be not less than 0.1MΩ; where the voltage to earth exceeds 150V, the resistance shall be not less than 0.2MΩ. And 500V DC insulation ohmmeter shall also be used to measure the insulation resistance between the wires of the detector circuit as well as between the wire and the earth, and the resistance shall be not less than 0.1MΩfor every alarm division.2.The signal loop of usually opened detector shall employ serial connection, and terminal resistor shall be attached for the gas leakage signal-receiving switchboard to perform automatic detection of disconnection.3.The circuit loop of detector may not be shared by equipments other than automatic fire alarm equipments for gas leakage.
中文原文 各類場所消防安全設備設置標準第144條
瓦斯漏氣火警自動警報設備之配線，除依用戶用電設備裝置規則外，依下列規定：
一、電源回路導線間及導線對大地間之絕緣電阻值，以直流五百伏特額定之絕緣電阻計測定，對地電壓在一百五十伏特以下者，應在零點一ＭΩ以上，對地電壓超過一百五十伏特者，在零點二ＭΩ以上。
檢知器回路導線間及導線與大地間之絕緣電阻值，以直流五百伏特額定之絕緣電阻計測定，每一警報分區在零點一ＭΩ以上。
二、常開式檢知器信號回路之配線採用串接式，並加設終端電阻，以便藉由瓦斯漏氣受信總機作斷線自動檢出用。
三、檢知器回路不得與瓦斯漏氣火警自動警報設備以外之設備回路共用。
