小區(qū)安保管理中心是系統(tǒng)的神經(jīng)中樞。管理人員通過(guò)小區(qū)安保管理中心的控制設(shè)備管理各子系統(tǒng)的終端，各子系統(tǒng)的終端只有在小區(qū)安保管理中心的統(tǒng)一協(xié)調(diào)管理控制下，才能有效正常地工作。因此，小區(qū)安保管理中心的地位顯得十分重要。小區(qū)內(nèi)各個(gè)子系統(tǒng)的控制設(shè)備可以**設(shè)置分管理中心，也可以集中設(shè)置在小區(qū)安保管理中心內(nèi)。例如廣播控制中心、消防控制中心、監(jiān)控中心等，可以合理地把它們?cè)O(shè)置在安保管理中心內(nèi)，進(jìn)行集中管理。 </p> <p> <br /> </p> <p> 樓宇對(duì)講系統(tǒng)的管理員機(jī)也設(shè)置在小區(qū)管理中心，管理員機(jī)的基本功能為：接收小區(qū)內(nèi)住戶呼叫信號(hào)并進(jìn)行通話、可以呼叫小區(qū)內(nèi)任意住戶并進(jìn)行通話、接收各單元主機(jī)的呼叫信號(hào)并進(jìn)行通話及開鎖（可視管理員機(jī)可顯示各單元主機(jī)視頻信號(hào)）、監(jiān)視***各單元主機(jī)情況。
