消防工程公司干式自動滅火器系統為噴頭常閉的滅火系統，管網中平時不充水，充有有壓空氣(或氮氣)。當建筑物發生火災，火點溫度達到控制點時，噴頭開啟噴氣、沖水滅火。該系統的優點是管網中平時不充水 ，對建筑物裝飾無影響，對環境溫度也無要求，適用于采暖期長或建筑內無采暖的場所。其缺點是在系統滅火時需要先排氣，故噴頭儲水滅火不如濕式系統及時。

1.系統布線：

（1）火災自(zi)動報警系統(tong)工(gong)程的布線，應符合現行國(guo)家(jia)標準《電氣裝置1KV 及以(yi)下(xia)配線工(gong)程施工(gong)及驗收規范》GB50258-96 的規定(ding)。

（2） 火災自(zi)動報警系統的傳輸線(xian)路(lu)的線(xian)芯截(jie)面，除滿足技術條件外，還應(ying)(ying)滿足機械強(qiang)度要求。穿管敷(fu)設(she)的銅(tong)芯絕緣導線(xian)小(xiao)(xiao)截(jie)面不(bu)應(ying)(ying)小(xiao)(xiao)于1.0mm2；線(xian)槽(cao)內(nei)敷(fu)設(she)的絕緣導線(xian)，小(xiao)(xiao)截(jie)面不(bu)應(ying)(ying)小(xiao)(xiao)于0.75mm2；多芯電纜(lan)小(xiao)(xiao)截(jie)面不(bu)應(ying)(ying)小(xiao)(xiao)于0.5mm2。

（3）其傳輸線(xian)路(lu)應采用穿金屬管，經(jing)阻燃處理的硬質塑料(liao)管或(huo)封閉式線(xian)槽(cao)保護(hu)方(fang)式布(bu)線(xian)。

（4）當采用暗敷(fu)設時，應敷(fu)設在(zai)不(bu)燃燒體結構內，且(qie)保(bao)護層厚度(du)不(bu)宜小(xiao)于3cm。

（5）當采用明(ming)敷時，應采用金屬(shu)(shu)管或金屬(shu)(shu)線槽(cao)保護，并(bing)應在(zai)金屬(shu)(shu)管或金屬(shu)(shu)線槽(cao)上涂(tu)防(fang)火(huo)涂(tu)料保護。

（6）當采用經阻燃處理(li)的(de)(de)電纜時，可不(bu)穿金屬管保護(hu)，但(dan)應敷設在(zai)電纜井或吊頂內(nei)有防火保護(hu)措施的(de)(de)封閉(bi)式(shi)線槽內(nei)。
