serial numbers for sensors

The serial number should be on the sensor itself. If not, a call to SimpliSafe will give you the answer (they have them on file).

If you have SS3, you can view the serial #'s by going into the keypad under system settings / devices.  Then for the specific device, scroll down on the menu and the serial # appears.  Otherwise, you can view the serial # on the device itself as @Shiherlis mentioned.

Hi,

For the All New SimpliSafe system, you don't need to enter any serial numbers. You'll just need to enter the Setup and Naming mode through your Keypad, and press the button on the sensor. It will be added automatically, and you can return to the Keypad to name it.
