TopWorx Switch Installed on a Safety Shower

Eye wash monitoring

When the eye wash valve is activated (valve open) by pushing down on the

hand paddle, the TopWorx switch is activated (closed switch) and the

Rosemount 702 Transmitter senses that switch closure. This switch state is

then transmitted by the Rosemount 702 Transmitter to the Gateway, which

then sends that information to the control host or alert system. When the

eye wash 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.
