The DSC WS4985 Wireless Flood Sensor is designed to alert compatible alarm systems to the presence of water. The device consists of a water probe that is attached to a wireless transmitter. The sensor operates at 433 MHz, making it compatible with the DSC Impassa and PowerSeries Systems.

The primary function of the DSC WS4985 is to be used as a flood sensor. The transmitter should be mounted up off the ground, with the water probe down in a location where a flood is most likely to occur. The device will activate when both of the probes come into contact with water. Some good locations for the WS4985b include basements, bathrooms, kitchens and laundry rooms. It is also smart to place the probe underneath water heaters the may leak.

The idea behind the DSC WS4985 is that it will alert the system when a flood is first occurring. The system will then alert the user to the situation. The user can then take action before any serious damage takes place. This can save the user a large amount of money and hassle in the event of a flood or a leak. The wire connecting the transmitter and the probe measures 6 feet in length.

However, the DSC WS4985 can perform other functions than just operating as a flood sensor. A built-in reed switch allows the sensor to operate as a door and window contact in conjunction with a magnet. Additionally, the device also includes a contact input. A normally closed hardwired device can connect directly with the WS4985. The sensor will then act as a wireless transmitter for the hardwired device, allowing it to communicate with the panel wirelessly.

Another feature includes a tamper switch to let the system know if anyone tries to tamper or disable the device. The sensor comes with a CR2 lithium battery that provides an average power life of 4 years. The battery can easily be replaced by the end user when needed.
