Safety shower monitoring
When the shower valve is activated (valve open) by pulling down on the handle, the TopWorx switch is
activated (closed switch) and the Rosemount 702 Transmitter senses that switch closure. This switch
state is then transmitted by the transmitter to the Gateway, which then sends that information to the
control host or alert system. When the shower valve is closed, the switch remains in the activated state
until it is reset by a technician. The switch can be re-set only by placing a ferrous metal object on the far
side of the sensing area of the switch.
