Powering the E-Kanban Call Button
You can supply power to the E-Kanban Call Button in two ways:
▪ The device can be powered by four AA batteries.
▪ The device can be connected to a +12VDC power source via its mini CT connector.
GuardRFID recommends that you use both power sources—if the device has access to both
battery power and wired power, the batteries act as a back-up in case the central power supply
fails.
Both the battery compartment and power connector are on the back of the E-Kanban Call Button,
which is typically inaccessible once the device is mounted. Install power sources before mounting
the device.
Battery Power
You can supply power to the E-Kanban Call Button using four AA batteries, which will provide
about 12 months of operating power Battery life varies according on usage frequency.
Note that if the device is powered by both 12VDC wired power and batteries, it uses the wired
power in preference.
Inserting batteries into the E-Kanban Call Button
Using a Phillips screwdriver, remove the three screws on
the back of the device. Remove the battery cover to
expose the battery compartment.
Insert four fresh AA batteries into the compartment,
taking care to orient them according to the diagram
embossed into the compartment’s surface.
Replace the battery cover and secure it in place using the
screws.
