<h3 id="alarm-sound-item-1">Choose an available output</h3>

<p>Location: Admin → Alarm Sound. Viewing requires alarm:view; editing requires alarm:manage and an installed Alarm Sound module.</p>

<ol>

<li>Add and name an output. Choose Zone Workstation Speaker (Browser) or Server General Horn (System Default).</li>

<li>Browser playback requires an open runtime page. Scan browser-accessible speakers and select an audio device; availability depends on browser support and permission.</li>

<li>The server general horn plays through the Windows host’s current default speaker without an open browser. It does not provide system playback on other platforms.</li>

<li>Agent, multi-card, IP horn and PLC/relay outputs marked unavailable cannot trigger alarms. Choose an available output and test playback; saving an unavailable output does not enable it.</li>

</ol>

<h3 id="alarm-sound-item-2">Configure rules, audio and scope</h3>

<p>An output can contain multiple sound rules. When several match, the highest-priority matching rule plays.</p>

<ol>

<li>Add a rule with a name, priority, audio source, volume and repeat interval. Upload an audio file or enter an accessible audio URL.</li>

<li>Configure the alarm area or groups for the rule. Any matching scope item can trigger it; an enabled rule must contain at least one scope item before saving.</li>

<li>Check the output switch and the global switch, then save. Reload reads the saved configuration.</li>

<li>Preview audio to check its source and volume in the current browser. A browser preview of a Windows system output does not verify the host speaker; check actual output at the host.</li>

</ol>
