Resideo 5800MINI Sensors: Potential Range Problems

Resideo’s recent MyWebTech Technical Notification #114 warns of potential range issues with certain 5800MINI transmitters. These units may have a poorly placed FCC sticker inside the cover, hindering their ability to communicate with the receiver. Both 5800MINI and 5800MINIBR are affected.

There are a number of circumstances that could cause range issues for a transmitter. Large metal objects such as appliances, duct work, and even some mirrors can affect the transmission path of a sensor. Even if the obstacle is not within a direct line-of-sight between the sensor and the receiver, the signal can be bounced away from the receiver. This may happen intermittently or consistently.

It's important to note that this issue is specific to a limited number of sensors. To identify affected units, you'll need to check the packaging. Look for a date code of 2429 or 2431 (YYWW format, indicating the year and week of manufacture). The packaging will also have the designation "Made in Taiwan." If your sensor matches these criteria, it may be impacted by this issue.

If you suspect your sensor is affected, it's crucial that you leave the metallic FCC sticker in place. Removing or tampering with the sticker is illegal and could void the warranty. Instead, you should contact your security system provider for further assistance.
