Alarm Grid has discovered a recent manufacturing mistake that has affected some Honeywell 5822T Garage Tilt Sensor units. The issue has resulted in the internal tilt detector for the affected units being positioned upside-down. We apologize to anyone who may have received an affected unit.
Inside every Honeywell 5822T is a pair of cylindrical metal pieces. These metal pieces represent the sensor's internal tilt detector that is used to determine whether the garage door that is being monitored is opened or closed. Because of a recent manufacturing error, the internal tilt detector for these sensors was positioned upside-down.
The following picture shows the tilt detection sensor in the proper position. Note how it is positioned facing the upper portion of the sensor.
And now here is a picture of a Honeywell 5822T where the tilt detector has been positioned improperly. Note how the metal cylindrical pieces are positioned facing the sensor's bottom.
At this time, we are not entirely sure of the date ranges for the affected sensors. So far, we have only seen incorrectly manufactured Honeywell 5822T units with a date code of D227, which represents August 14, 2020. We have also seen newer Honeywell 5822T units with a date code of D255, which represents September 11, 2020 that do not have this issue. Based on that info, it's likely that Resideo has already corrected the mistake in manufacturing, and we are only just now discovering the issue due to reports from customers.
Below is a picture of the date code for one of the improperly manufactured 5822T units. Note that D represents the year 2020, while 227 represents the 227th day of the year, or August 14th, with 2020 being a leap year.
The good news is that the improperly manufactured units are still usable. When using the 5822T as a garage tilt sensor (Loop 3), you just need to mount the unit upside-down so that the internal tilt detector is facing the proper direction. Normally, these devices are mounted at the top of the garage door with the arrow pointing upward. If you find that you have an affected unit, just mount the sensor in the same location with the arrow pointing downward. If you are only using the Honeywell 5822T as a wireless transmitter (Loop 1), then you can position it in any direction, as that function is unaffected by the manufacturing error.
The picture below shows the arrow on the outside of the Honeywell 5822T. The sensor is typically installed with the arrow facing upward, but an affected unit can be used for regular operation by being installed with the arrow facing downward.
