Funkinnenanschlußdose
These are the boxes which hung in the Funkraueme and proved a connection to the transmitters and recievers. The Funkinnenanschlußdose was connected to the Funkaussenanschlußdose (FuIAd) in the entrances (antenna shafts). Per 1 set of antenna niches one FunkInnenanschlussdose was used. The Festungsantenne and the interior (the real connection-bit of the FuIAd) were normally stored in the FUnkschrank. In a 618 this was placed in the antenna room

Great initiative! I'll add what I find most interesting, technical sketches, to it. (Thanks to Radar for helping me out a long time ago)
Heating
Wt 80
In order to make the large betong structures such as bunkers and especially fortresses possible to live in for a longer time, heating would be required. Early makeshift solutions such as building a stove into the bunker was time consuming as was finding a stove which would fit a bunker. This proved a standard solution was required, and such was the German decision.
The company W. E. Haas und Sohn (Sinn in Dillkreiz) was given the contract of creating a "[...] for fortifications designed oven, giving heat worth 5000-6000 kcal/h while remaining gas- and pressure proof [...]". This "contraption" was given the name Wt 80. The stove was manufactured by this company until another function was needed which had been left out them improve the design.
See manual with technical sketch and the drawing below.
Wt 80 K
It was not long until one important function had been forgotten when the Wt 80 was designed. For this, an improved version, the Wt 80 K, was developed. What made it different was that while on the earlier model the exhaust was on top of the device, on the revised version the exhaust was mounted on the side and on top was a "Kochplatte" (cooking plate), which added the K to the name.
With this new feature you could boil water and heat food, something which had a large positive impact on morale during the defence of the Westwall, winter 1944-45.
See 3D model/photo and drawing below.

Central heating was used in large bunkers where regular ovens didn`t provide enough heat. The system can often be seen in hospital bunkers, headquarters etc.
The main part is the boiler oven.(Warmwasserkessel) This came in 17 different versions, depending on the size of the bunker. The smallest with 18 litres of water, the largest with 139 litres. On top of the oven is a small manometer, showing the pressure in the system.
Just above the oven, a expansion tank were placed. (Ausdehnungsgefäß für Warmwasser Heizanlagen) This tank came in 4 different versions, from 35 to 100 litres. From here, pipes went out to radiator ovens placed in each room which needed heating.
As an option, the outgoing hot water line could go via a airheater connected to the ventilation system. The water would simply cirulate through a spiral placed inside the incoming fresh air pipe, and provide some heating before the air was let into the bunker. (Warmwasser Lufterhitzer)

Hi All
El9.JPG
SIicherungskasten 6-paarig: fuse-box for telephone connections
el3.JPG
fortress telephone exchange for 30 lines
Festungsvermittlung zu 30 Ltn
wit on top two battery-boxes (Batteriekasten Groß)
and to the right the main internal cable-divider (Hauptverteiler, 60 x 60 DA) with below the KEVs
El3a: this is the frontboard of the telephone exchange with the connection holes. In stead of the normal cables to plug into the connection holes,
the fortress exchanges used bakelite connector

I never knew a bunker could have so much equipment!-

Please, feel free to add what I posted above, except for the Wt 80/Wt 80 K sketch which I'm not sure where I found...Erik E wrote:Important notice

Also, I think we should have blueprints, sketches, circut topologies and whatever else might be interesting. If anyone has the original WW2 copy, they aren't affected by copyright any more, right?

alarm.JPG
I don't know this type exactly (perhaps a navy one)
but the best name to describe it is as an 'Alarmwecker'
telefon.JPG
Normal bunkertelephone (Festungsfernsprecher 38)
with a post-war electricity box
Kleine festungsvermittlung ob37.JPG
Indeed the Festungsvermittlung zu 10 Ltn.
The smalles was for 5 Ltn. Then there was one for 10, 20, 30 & 40 lines.
These were al very similar wall-versions, only differing in size.
The Festungsvermittlung zu 100 ltn is a standing switchboard, similar to the Große Feldvermittlungen, but then in a steel frame.
