Re: PIR's: Why trip on two detects?

["Crash Gordon" <webmaster@xxxxxxxxxxxxxxxxxxxxx>]

Are you talking about Pulse count?...that's not quite the same as two trips.

I use pulse count all the time, the count I set it at depends on the
conditions of the room, harshness of the evironment, dogs, kids, mirrors,
fans, fax machines, heat/cooling ducts etc.
