DIVERSITECH ASURITY Wet Switch WS-1 User manual

Wet Switch prevents flooding and property damage by detecting moisture
caused by accumulation of air-conditioning condensate, drain leaks, etc. When
moisture is detected, the normally closed circuit controlling the system is
disconnected. An additional circuit is included, normally open, that may be used
to operate an alarm device as well. Multiple Wet Switches may be connected in
series (within the electrical limits of the power supply), to expand coverage area.
Wet Switch incorporates isolated relay contacts, for added flexibility in
installations with electronic control boards where breaking one lead from the
transformer is not possible.
Status Indications & Operation
Normal State: When power is applied and no moisture is detected, the
“POWER ON” LED will be lit green, and the “MOISTURE” LED will be OFF.
Pressing TEST button simulates moisture detection and confirms proper
function of Wet Switch. “MOISTURE” LED will be lit red, & “POWER” LED will be
OFF.
Press RESET button to return Wet Switch to normal state.
When moisture is detected, the control circuit is opened, and the “MOISTURE”
LED is lit red. Wet Switch will remain in this state until the problem is corrected
and the RESET button is pressed, or power is disconnected. After correcting
the moisture problem, & with power disconnected, use a clean, absorbent cloth
to thoroughly dry the sensor pad on the bottom of Wet Switch. Any residual
moisture in the pad may cause a false detection. A warm air device (such as a
hair drier on low heat ONLY) may be used to help dry the pad.
Installation
1. Turn off power to the system.
2. Place Wet Switch, padded side down, on the surface to be monitored.
3. Connect wiring as shown in the diagrams on page 2. Wires may be
extended as necessary, but avoid excess run lengths.
4. Restore power to the system.
5. Press “TEST” to assure proper function.
Controlling Selected Components
System components such as compressors, electric valves, condenser
pumps, chill water pumps, or other 24 VAC controls may be connected
selectively and independently
to Wet Switch.
