Adding a water/flood sensor to a Concord 4

Hi all,
I'm in the process of adding a couple of water/flood sensors (GRI 2600) to my existing Concord 4 system. They are all hooked up hardware-wise, now I'm trying to determine which group to place them in to get the following desired behavior:
When they trip I would like the system to give me an indication of the problem, but not fly off in a panic. A periodic beep/chirp and possibly a voice announcement would be perfect. I would like this notification to repeat every few minutes or so (1/3/5/10/etc minutes - don't really care about the actual period), but not be continuous and not set off any of the alarm modes. I would also prefer if it would reset after the condition goes away (after I pull the sensor out of the water and start addressing the problem).

I began by learning them into Group 19 (Freeze sensor) - but when they trip that group is setting off the Auxiliary alarm and basically just raising holy hell.
I next tried Group 25 (Local Special Chime) and that produces a much better notification, but as far as I can tell it only notifies when the sensors first trip and doesn't repeat as long as the condition continues to exist.

I there something similar to the default Group 25 that will continue to notify periodically as long as the sensor remains tripped?

Thanks in advance for any suggestions.

Group 25 is going to get you the closest to what you want...
You could play around with output programming and hook up a sounder and program it to go off for X amount of time every time that sensor or better yet, any sensor in that sensor group (25) goes off...

That's what I was afraid of. In that case I'll probably look into adding a small circuit to the sensor loop to turn the continuous signal from the sensors themselves into a periodic signal to the alarm panel.

Thanks for the reply!
