Cocoa - Fire alarm variant

[NLCaelum]

I noticed that cocoa hasn't been retextured. There are 3 variants that hang on walls, so maybe one or two of them could be a fire alarm? All buildings should have them, especially those coming up in DT. They can be the old-school bell version or the modern one with a strobe light. The other one could be a motion sensor or some other kind of wall-mounted security device.
