Shema je preuzeta iz sirene koja je bila na popravku. Za zvučnik bi bilo najbolje upotrijebiti srednjotonski rog. Uz originalnu shemu priložena je i shema zavijajuće sirene slične konstrukcije. Zvuk nije sličan kojak sireni već nekakvoj sireni upozorenja (riba-riba-riba zvuk). Taj zvuk je iskorišten u budilici koja se ne može prespavati, a zvuk joj se čuje i izvan kuće. Razlika je i u manjoj snazi (2W) te što kroz zvučnik ne teče DC struja (tj. teče neka zanemariva). DC struja kroz zvučnik dodatno izbacuje membranu i smanjuje njen mogući linerni hod. Utječe naravno i na češće trganje membrane.</div> <bR> <script async src="https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js?client=ca-pub-2650537455752702" crossorigin="anonymous"></script>  <ins class="adsbygoogle" style="display:block" data-ad-client="ca-pub-2650537455752702" data-ad-slot="7117608876" data-ad-format="auto" data-full-width-responsive="true"></ins> <script> (adsbygoogle = window.adsbygoogle || []).push({}); </script> <div>      Karakteristike:</div> <bR> <div> <IMG BORDER="0" SRC="Symb075c00b700f000000000.gif" HEIGHT="16" WIDTH="24" ALIGN="bottom" HSPACE="0" VSPACE="0">Napajanje: 12V=</div> <div> <IMG BORDER="0" SRC="Symb075c00b700f000000000.gif" HEIGHT="16" WIDTH="24" ALIGN="bottom" HSPACE="0" VSPACE="0">Zaštita od reverznog spajanja napajanja</div> <div> <IMG BORDER="0" SRC="Symb075c00b700f000000000.gif" HEIGHT="16" WIDTH="24" ALIGN="bottom" HSPACE="0" VSPACE="0">Izlaz: zvučnik 8R/6W</div> <div> <A HREF="shema_originalne_kojak_sirene.htm" TARGET="_top" TITLE="Original kojak shema"><U><IMG BORDER="0" SRC="Symb075c00b700f000000000.gif" HEIGHT="16" WIDTH="24" ALIGN="bottom" HSPACE="0" VSPACE="0">shema</U></A></div> <bR> <bR> </td> </tr></table></body>
