I was thinking about a server I would like to make, and mentally doing a checklist of things a city might need, and as a smoke detector at work (irl) beeped for the THOUSANDTH TIME, I thought about the smoke detectors in your mod already, and couldn't remember if they emitted a redstone signal when they went off or not. if so, they could easily link up to a sprinkler that would be ceiling mounted.

Just thinking about protecting wood/wool houses (or skyscrapers) from disaster by setting up a fire suppression system that would activate when the smoke detectors did. Some mods add sprinklers that irrigate crops and/or fertilize them (Openblocks adds a decent one that needs a source of water, and there was another that was ceiling mounted that was fed from a barrel type storage that I think could be filled by rainwater)
