背景音乐接2个常闭端子，继电器的控制引脚接应急广播模块的24V电压线，应急广播接2组常开端子！不知对否？？

<p>消防广播一般都有广播切换模块，你把背景音乐接到常闭点，把消防广播线接到常开点就可以了。下面是海湾的模块的接线说明：</p><p class=MsoNormal style="MARGIN: 0cm 0cm 0pt 18pt; TEXT-INDENT: -18pt; mso-list: l0 level1 lfo1; tab-stops: list 18.0pt"><span lang=EN-US style="FONT-FAMILY: 宋体; mso-bidi-font-size: 10.5pt; mso-bidi-font-family: 宋体"><span style="mso-list: Ignore"><span style="FONT: 7pt &#39;Times New Roman&#39;">&nbsp;</span></span></span><span style="FONT-FAMILY: 宋体"><font size=3>接线说明如下：</font></p><p class=MsoNormal style="MARGIN: 0cm 0cm 0pt; TEXT-INDENT: 42pt; mso-char-indent-count: 4.0"><font size=3><span lang=EN-US style="FONT-FAMILY: 宋体">D1</span><span style="FONT-FAMILY: 宋体">、<span lang=EN-US>D2</span>：<span lang=EN-US>DC24V</span>电源，无极性。<span lang=EN-US><?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /><o:p></o:p></span></span></font></p><p class=MsoNormal style="MARGIN: 0cm 0cm 0pt; TEXT-INDENT: 42pt; mso-char-indent-count: 4.0"><font size=3><span lang=EN-US style="FONT-FAMILY: 宋体">Z1</span><span style="FONT-FAMILY: 宋体">、<span lang=EN-US>Z2</span>：信号总线输入端，无极性。<span lang=EN-US><o:p></o:p></span></span></font></p><p class=MsoNormal style="MARGIN: 0cm 0cm 0pt; TEXT-INDENT: 42pt; mso-char-indent-count: 4.0"><font size=3><span lang=EN-US style="FONT-FAMILY: 宋体">ZC1</span><span style="FONT-FAMILY: 宋体">、<span lang=EN-US>ZC2</span>：正常广播线输入端子。<span lang=EN-US><o:p></o:p></span></span></font></p><p class=MsoNormal style="MARGIN: 0cm 0cm 0pt; TEXT-INDENT: 42pt; mso-char-indent-count: 4.0"><font size=3><span lang=EN-US style="FONT-FAMILY: 宋体">XF1</span><span style="FONT-FAMILY: 宋体">、<span lang=EN-US>XF2</span>：消防广播线输入端子。<span lang=EN-US><o:p></o:p></span></span></font></p><p class=MsoNormal style="MARGIN: 0cm 0cm 0pt; TEXT-INDENT: 42pt; mso-char-indent-count: 4.0"><font size=3><span lang=EN-US style="FONT-FAMILY: 宋体">SP1</span><span style="FONT-FAMILY: 宋体">、<span lang=EN-US>SP2</span>：与广播音箱连接的输出端子。</span></font></p><p class=MsoNormal style="MARGIN: 0cm 0cm 0pt; TEXT-INDENT: 42pt; mso-char-indent-count: 4.0"><font size=3><span style="FONT-FAMILY: 宋体"><span lang=EN-US><o:p></o:p></span></span></font>&nbsp;</p><p class=MsoNormal style="MARGIN: 0cm 0cm 0pt 18pt; TEXT-INDENT: -18pt; mso-list: l0 level1 lfo1; tab-stops: list 18.0pt"><span lang=EN-US><o:p><span lang=EN-US style="FONT-SIZE: 10.5pt; FONT-FAMILY: &#39;Times New Roman&#39;; mso-bidi-font-size: 10.0pt; mso-fareast-font-family: 宋体; mso-font-kerning: 1.0pt; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA"><?xml:namespace prefix = v ns = "urn:schemas-microsoft-com:vml" /><v:shapetype id=_x0000_t75 stroked="f" filled="f" path="m@4@5l@4@11@9@11@9@5xe" o:preferrelative="t" o:spt="75" coordsize="21600,21600">&nbsp;</v:shapetype></span></o:p></span></span></p>

顶楼上。

<br />如楼上所言，把常开常闭记住就行了。
