APPLICATION CONSIDERATIONS:
The RS-094 system is designed to prevent damage caused by undetected plumbing leak 
from a water tank. The full port valve installs on the cold water inlet line to the water 
heater, and the snap-t actuator attaches directly to the valve mounting pad. A leak 
detection sensor is placed in the pan or on the oor under the tank, typically under the 
pressure relief valve or in a similar area where water from a leak is likely to accumulate. 
INSTALLATION OVERVIEW:
The RS-094 plugs into a standard 120V AC wall outlet. Components come  
pre-wired. The system can be performance tested anytime; it is resettable via reset 
button on actuator. Suitable for new construction or retrot, gas-powered or electric 
tanks, conventional or tankless systems. Optional dry contact connections (NO/C/NC) are 
available for fault notication to existing security panel or BMS. 
Emergency manual operation of the valve is accomplished by removing the snap-t 
actuator and manually changing the valve to open or closed. In the event of a power 
failure, the valve will remain in position (either open or closed).
