Overview

What it is and who it is for

The DSC WS4985 is a 433.92 MHz wireless flood detector. A two-probe water sensor on a 1.82 m (6 ft) cable sits at low points such as the floor, and the transmitter sends an alarm when both probes touch water. It works with RF5132-433, SCW9045/47-433, RFK55XX-433, PC4164 and PC9155 receivers and systems.

The transmitter runs on one CR2 lithium battery (Panasonic or Duracell) rated for 4 years of typical use. A case tamper reports removal of the transmitter cover, a longer rubber actuator adds wall tamper, and cutting the sensor wire also reports a tamper. The transmitter operates from -10 to 55 C (14 to 131 F) at up to 85 percent relative humidity and mounts with screws or adhesive tape; the sensor has two wall and two floor mounting holes with screws included.

  • Best for: detecting water at low points where it collects first, such as the floor.
  • System fit: RF5132-433, SCW9045/47-433, RFK55XX-433, PC4164, PC9155.
  • Important to know: do not place the transmitter behind metal objects such as washing machines or refrigerators, and test the detector at least once a year.
