Where do I find the serial number for my 5816 wireless sensor?



There are typically two stickers on the 5816 wireless sensor where the device serial number is printed.


One sticker, which is sometimes removed by professional installers, is located on the outside of the device. The serial number is formatted like this: A###-####. If you can't locate this sticker, open the cover of the device and look for a long sticker on the circuit board. This should also contain the printed serial number for the device. If neither sticker is present, users can employ the sensor trip programming mode to retrieve the serial number from the device if they have a wireless security system, like the L5100.
