Re: Automatic flushers

["Paul O. Johnson" <pojhome@SWBELL.NET>]

I asked the facilities chap for our campus. I had discovered experimentally
that the sensor was IR, that it set itself when a large enough object stood
within the specified range, and that it then executed a flush when the
object moved away. But I couldn't determine how it caused the flush.

Our facilities man said it was battery powered and that the batteries were
supposed to last over a year, but he didn't know how it worked.

I called the manufacturer in North Carolina. The person I talked to said he
would send me a paper describing the design and operation of the unit but he
never did.

So I'm as eager as SSHS is to find out how the damn thing works.
