Has anyone tried placing multiple sirens in settlements?

I've seen a settler run to one and sound the alarm after all the gunfire starts during an attack, but does it help if you space more around the whole settlement?

I haven't placed any of these yet, so I'm interested in how that'd work.

I've never built one as it seems all my settlers immediately react without any need for any warning, usually they also all sprint out from behind the fortified walls I have built for them to engage the enemy as well....please guys you could at least wait until they have made it though the minefield, past the massed battery of turrets and made it over the walls before you decide to fight the enemy.

I'm not sure what the siren does?

Wake sleeping settlers when they are attacked?

They always seem to be awake and ready to fight when I arrive.

If you place too many sirens it just leaves less settlers to start shooting..

For example if you have 8 settlers and 5 sirens..5 settlers will run to the sirens, leaving only 3 to start defending...

That's all just a hypothesis tho...I've never used a siren before

I haven't seen much point in sirens. Settlers and turrets often start shooting when targets are way out in the weeds, immediately the whole settlement rushes over.

Is there a point to them?

They are utterly useless.

Yes, I have two in sanctuary, one by the bridge, the other at the other side of town. I place them next to guard platforms. More than a few times I hear a turret firing then the siren going off. But only the one near the firing turret.

The settlers will then head towards the sounding siren, once close they then move towards the firing turret.

I've not seen the second go off after the first. And a settler needs to turn it on, so if you only have one in the middle of town they will turn that on and head there, unless the attack has started.

It's saves time, I got a noticed lastnight to defend the castle. I got there fast and saw a group coming up the road.

At the castle I put one by the radio, I ran over hit the siren. Settlers started gathering with guns drawn when the attack happen, was over fast.
