SYSTEM COMPONENTS
Perimeter Antenna
The signal generated by the
CentralTransmitter
is carried around the
designated store perimeter
by a small, embedded cable
known as the “Perimeter Antenna”. This antenna is embedded in a 1/4” wide by 1” deep
saw cut around the parking lot which is sealed using a weatherproof sealant. The
location of the perimeter antenna determines the boundary where carts will lock. The
perimeter boundary is typically identified by a thick, painted yellow line found at all
parking lot exits.
Gatekeeper wheel
Each shopping cart is equipped with Gatekeeper’s locking wheel.
Inside each wheel is a signal receiver and locking mechanism.
The receiver is factory programmed to listen for the locking signal
emitted from the perimeter antenna. The Gatekeeper wheel also
accepts a locking or unlocking signal from a CartKey remote control.
CartKey2
The CartKey is a handheld device used by store employees to lock or
unlock Gatekeeper wheels. The touch pad on the front of the CartKey has two
buttons labeled “Lock” and “Unlock”. Use the “Unlock” button to unlock
carts that have locked wheels. Gatekeeper recommends that
you keep at least one CartKey in a secure location at all times in order to
avoid losing or temporarily misplacing all CartKeys.
