Description

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.

Reviews
Outstanding 433 MHz Flood Sensor
Submitted on 10/17/2019 Alarm Grid

The DSC WS4985 is a wireless 433 MHz flood sensor intended for use with the DSC Impassa and DSC PowerSeries Panels. It also works with other 433 MHz panels like the legacy DSC version of the IQ Panel 2 Plus. This sensor works very reliably, and it packs some nice bonus features as well. For a flood sensor, it is actually very robust, making it a great addition to nearly any compatible security system. For those reasons, we can confidently give the DSC WS4985 Flood Sensor a 5-Star Rating.

The main reason to get a DSC WS4985 is because you have a system that supports 433 MHz sensors and you need to add a flood sensor. The sensor is generally placed in areas where floods or water leaks are likely to occur. These areas can include in basements, in bathrooms, underneath sinks, under toilets, under water heaters, and more. Upon detecting a small amount of liquid, the sensor will send an alert to the panel. The system will then respond based on its programming settings. Our technicians have tested out the DSC WS4985, and we find that its flood detection functions work quite well. The sensor includes a detachable probe for use as a flood sensor.

However, there is more to the DSC WS4985 than just supporting flood detection. The sensor also includes a built-in reed switch. If you add a separate magnet, then the device can be used as a door and window sensor. In that case, you would most likely want to detach the probe. You can even have the sensor act as a wireless transmitter for a Normally Closed hardwired contact by using its built-in terminals. This is great if you have a hardwired contact with a large magnet spacing gap, and you want to use it with a 433 MHz system.

Bottom line, the DSC WS4985 works well, and it offers some nice bonus features that go above and beyond for a regular flood sensor. We give it 5 Stars.
