Tyco Water Flow Switch Vane Type

Product Description

The TYCO Model TF Vane Type Waterflow Switch detects a
waterflow condition in a wet sprinkler system.
The switch assembly contains single-pole, double-throw
(SPDT) contacts, and an adjustable pneumatic vane. The
switch activates when a flow rate that exceeds the flow
sensitivity of the switch occurs. The flow condition must
exist for a longer period than the retard delay setting of
the vane for the switch to operate. For information about
the retard delay time ranges, see Retard delay times
