Flood Sensor ?

[Johnic]

I have an ACIII and its hooked up to the internet and I would like to have a flood sensor also hooked up to alarm me if water levels rise in sump and dump on to the floor....how is this done ?

For the water on the floor sensor you can use the waterbug (WB-200 the AC powered version with relay contacts. A search on google will find many places that sell them. The digital input of the AC3 connects to the relay, and you'll add something like:

If Switch1 CLOSED Then ALM ON

to your alarm statements.

Great ...thanks, which one is the Digital Input on the AC II again ? How is it labeled on the unit ?

I would think that you would want to know before the water gets on the floor... install a float switch at the 1/2 way between the waterline and the top of the sump.. then use curts code

If Switch1 CLOSED Then ALM ON

How do you wire the serial port to the sensor ?

There is a wiring diagram on pg 40 in the current manual. You need to wire it to pin 1 & 8 of the I/O port. I just bought a Mini-Din 8 cable from a local computer store (they are old Mac printer cables), and stripped it down. Then solder it to your switch and you are done. You can use pin 2 & 8 for another switch if you want to control a auto top-off.

Most just open the DB9 end of our serial cable and attach the float switch wires there.
