Hello!
This is an update on MOD Longtown's siren system (which still appears not to be on the map, but oh well):
So, thanks to user 'Secomak_GP12' (Otherwise known as 'HM SirensAndFireAlarms' on platforms such as YouTube), I have been able to locate one of the site's warning sirens which is visible from the main road! Secomak_GP12 "Saw (a siren-like object) that looked white" from the M6 motorway that runs alongside the site, and prompted me to go down and have a look. I managed to locate a road which would allow me to get a better view than from the M6, so on Monday we headed down there to check it out.
Unfortunately, the white object was not a siren, and actually turned out to be a concrete vent of some description. However, beside it was an orange and black dual-tone siren, which had been mostly invisible from satellite view as it blended in with the building it was installed on. The siren was still quite far away from where we took photos from, and we could not get any closer due to the perimeter fences. I am not entirely sure on the make or model of the siren, I couldn't make out any distinguishing features myself, but perhaps someone with more knowledge than me might be able to identify it.

Another point of interest is that when I recorded Longtown's system, the direction that the sound of the dual-tone siren came from does not match up with this new siren's location, in fact this siren is installed where I predicted the single-toned siren to be situated. What confuses me further is that on the day of the recording, I only heard two sirens sound. I know I shouldn't base something solely on satellite view, but the siren that is at '54.98662728847818, -3.0082701973516244' is definitely dual-tone. So, as far as I'm concerned, I believe that this new siren is most likely inactive. However, I will still attempt to record it at some point to confirm this.
The new siren's location is '54.981360537109104, -3.019961331572023'.

Thanks again to Secomak_GP12 for alerting me to this location!
Have a good day,
