&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;&lt;br /&gt;
= List of requirements for smoke detection system =&lt;br /&gt;
&lt;br /&gt;
* Smoke detection&lt;br /&gt;
* Interconnection (one goes off they all go off)&lt;br /&gt;
* Ability to silence the whole system without some special access key and keep it silenced for some small period of time without manually having to turn it back on (snooze)&lt;br /&gt;
* Ability to run off battery power for x years (let&amp;#039;s say 3 min)&lt;br /&gt;
* Ability to report via SMS / phone calls to a list of people&lt;br /&gt;
* Primary and backup internet connection for reporting (e.g. ethernet and fallback to 4G)&lt;br /&gt;
* No cloud subscription required (a VOIP subscription for sending SMS and calling is ok but shouldn&amp;#039;t be tied to one provider)&lt;br /&gt;
* No IT infrastructure maintained by us (we don&amp;#039;t want the reporting function to fail if one of our servers goes down)&lt;br /&gt;
&lt;br /&gt;
Nice to have:&lt;br /&gt;
&lt;br /&gt;
* CO detection&lt;br /&gt;
* Report tells us which of the alarms that detected the smoke so we don&amp;#039;t have to search all of Omni&lt;br /&gt;
* Ability to engage the snooze feature from more than one location&lt;br /&gt;
* Ability to run a system test where messages are sent but include some &amp;quot;THIS IS NOT A REAL EMERGENCY&amp;quot; header&lt;/div&gt;</summary>
