Honeywell 470PB Posts

Resideo announced last week that due to a required component becoming obsolete, they are forced to discontinue the popular 5800FLOOD sensor. There is still some available stock, so Alarm Grid has not yet discontinued it, but once all stock has been exhausted, the 5800FLOOD is gone for good.

The 5800FLOOD is popular because unlike the 5821, it doesn't require that a water probe be added to the sensor. Water detection is built-in, and configuration is easy. Another benefit of the 5800FLOOD is that it will alert for flooding more quickly than the 5821. The prongs of the 5800FLOOD need only be in contact with water for about 25 seconds before a signal is sent to the alarm panel. The 5821 flood probe must be in contact with water for about three (3) minutes before sending a signal.

In addition to flood sensing, the 5800FLOOD also monitors for extreme cold and/or hot temperatures locally. This is done using a temperature sensor that is built into the 5800FLOOD. For cold temperature sensing, if the ambient temperature drops below 45℉ (7.2℃) for more than 15 minutes, an alert is sent using Loop 1. For high-temperature sensing, if the temperature rises above 95℉ (35℃) for more than 15 minutes, then an alert is sent using Loop 2. The flood sensor transmits using Loop 3.

Now that the 5800FLOOD is being discontinued, the Resideo and Honeywell Home 5821 is the recommended replacement. One drawback to the 5821 is that it requires a remote probe be added for flood sensing, and for freeze sensing. However, only one (1) remote probe can be used per transmitter, so if you need to monitor for both flood and freeze, two (2) 5821s are required.

The 5821 supports the following functions:

For flood sensing, we recommend using the FP280 as it includes wiring, and the required resistor is already in place. With the 470PB, the user is responsible for providing their own wire and must add the 2.2 MΩ resistor themselves. In all cases, wiring between the 5821 and whichever remote probe is used should be made as short as possible, and should not exceed 96" (243cm). Be sure to read the full Install Guide for the 5821 for all of its various quirks.

Supply chain shortages claim another victim in the 5800FLOOD. It seems like only yesterday that we were excitedly telling you about it. What are your thoughts on the demise of this "New and Improved" environmental sensor? Leave us a note in the comments, as we always love hearing from our readers.

Just last week, Resideo purchased startup company Buoy Labs. This is the first acquisition from Resideo since the company completed its spin-off from Honeywell in October of last year. The purchase of Buoy Labs should greatly assist Resideo in its technology for environmental sensors.

Buoy Labs is best known for its smart home products that allow users to track the amount of water they use and quickly identify leaks. Their lineup fits in perfectly with Resideo. The company already offers many great flood detecting sensors. These include the Honeywell 5800FLOOD and the Honeywell 5821 when used with a Honeywell 470PB Probe or Honeywell FP280 Probe. Many of our monitored customers use these sensors to receive alerts in the event of a water leak. They can then take action before serious water damage occurs. This equipment works great with the wireless panels from Resideo, including the Honeywell Lyric Controller.

We believe that this acquisition will help Resideo make fantastic strides in its offering of environmental sensors, particularly for flood sensors. Buoy Labs has an impressive portfolio of smart home water management and water leak detection products. Resideo has cited industry studies claiming that homeowner's insurance companies pay more than $9 billion in water damage claims every year. The average claim is roughly $9,000. With the purchase of Buoy Labs, we expect that Resideo will achieve great success in reducing these figures and preventing house floods. And if you still don't think flood sensors are important, think again.

Alarm Grid will certainly keep you up-to-date with the latest news regarding any new environmental or flood sensors released from Resideo. This acquisition means Resideo has some big plans in store, and we are very excited to see what the future holds. Stick with Alarm Grid as we move forward in the exciting worlds of security, property protection and home automation!
