Sensor 49 ??

my account shows a sensor #49, sensor name is contact(49).

any idea what this is?

There are 48 wireless zones on a 2GIG Go!Control, (60 with 1.14 firmware, though the extra 12 start later than 49)

49 would refer to the first hardwire zone (there are two)

If you do not actually have a hardwire sensor wired to your panel, check to make sure this zone was not accidentally enabled in programming. After entering system configuration you can just press the “Skip” button once to jump directly to the first Hardwire zone.

thanks that was it.
i just deleted it (unused)
i must have accidentally cursored over there
