Sprinkler Timer Stations

The Rain Bird ISM is an electronic timer that

controls when your sprinkler system turns on,

and how long the sprinklers run.

The ISM can control 4, 6 or 9 watering

“stations” (depending on the model). A

station is a series of sprinklers, or other

irrigation devices, connected to a common

remote control valve. When the valve

receives a signal from the timer, the valve

opens and turns on the sprinklers connected

to it.

This illustration shows a diagram of a station

layout. Station 1 is currently watering. When

station 1 finishes, the timer shuts it off and

turns on station 2. When station 2 finishes

watering, station 3 begins, and so on.
