A couple sensor questions (water/occupancy)
Posted 20 July 2012 - 11:12 AM
Second is water sensors. I was looking at some shut off valves, I'd like to wire for them at ever water location. Again, not sure I'll use them. My question is do I have to have some of the all in one solutions? Can I just get flood sensors? Can they be extended, I'd assume they work on a resistance system, and thus shorting across when water is on them, though not sure. Can anyone shed light. I'd rather have them as an input, drive outputs, or dry contacts, and pull separate wire for the solenoids. Or locate them at my header (though at fixture is better for leaks. Also what brand are recommended for valves/sensors?

Slow ramp rates can be used to mask this and if you are using ELK wiring to the main control zones and using fast loop response may help.

As far as water sensors I am curious about those as well, hopefully someone will chime in, the flood sensors seem to be all that is available and they are usually 4 wire. I was hoping for a "plate" type solution too, it seems like a certain height of water would be required to activate the flood sensors so they would have to be carefully placed. I really need to get one on my HVAC as I had a clog in my condensation hose last year and it flooded part of my basement and the A/C is running all the time these days....

I don't see anything that is a plate type sensor that can be connected to a panel directly, I ordered a couple of GRI 2600 Closed Loop to play with but I would still prefer a plate type 12v sensor for certain places, if you guys find a link to something like that please post.
