plc5 oil pit alarm logic

Hi again all..
I am having a little bit of a problem creating an alarm for a oil pit spill. I think im making it out to be harder that what it really is.
Here is what i have:
float contact=I:1/14
alarm reset PV pb=B3:0/11
alarm=n7:152/11
timer= T4:4
The float rises, and the contacts are made..alarm is on.
Hit reset,and the alarm shuts off for 20min then comes back on every 20 min until I:1/14 dropes out.
I must have brain lock,I should be able to creat the logic but keep finding flaws in it.
Thanks again

Not exactly how I'd do it, but it should work...
The "TT" bit is the timer's "Timer Timing" bit (T4:4/TT). I included the ALARM contact in the timer's rung so no one can 'anticipate' the alarm and start the 'silence' timer...
