Safety shower and eye wash monitoring

The Rosemount 702 Transmitter can be used to monitor safety showers and eye wash stations by using
switch kits provided by TopWorx
transmitter model code and are available for both insulated and un-insulated pipes. These kits contain
the switches, brackets and cables that are necessary to install the transmitter to monitor both the safety
shower and the eye wash in a single station. Because each has two input channels, one transmitter can
be used to monitor both a safety shower and an eye wash.
Each Safety Shower Monitoring kit contains:
Two TopWorx Go Switch magnetic proximity switches

Two cables, one six foot and one 12 foot

Two black polymer cable glands

Mounting kit for safety shower and eye wash
