The SD-RO1 is a single zone spot detector with one generic relay output. It can be used in conjunction with any product that accepts a digital dry contact input.
Spot detectors are ideal for small spaces, and are the most economical way to detect fluids in confined areas, such as condensation drip pans.
If the SD-RO1 is operating on 24VAC power, the circuit will reset and open automatically once a detected leak is no longer present. If the SD-RO1 is operating on 24VDC power, the circuit must be manually reset after a leak is detected and cleared. To do this, you must break power to the device, which will reset the circuit. Even if the water leak is no longer present, power must be broken to manually reset the DC-powered SD. The easiest way to accomplish this manual reset is to install a reset switch on either the positive or negative wire of the power supply that feeds into the SD-RO1.
