The TX-VLA1 power supply input accepts an ac or dc voltage from 12 to 24 volts. 12 Vdc batteries may power the TX-VLA1 in
remote applications. A common low voltage ac supply may power the module together with the camera in security installations
provided the camera is internally ground-referenced. The TX-VLA1 is a negative ground-referenced product. In the unlikely event it
is connected on a common ac supply together with a camera which is positive ground-referenced and not transformer isolated, a
“ground fault” may occur. The TX-VLA1 automatically detects such a fault, disconnects itself from the power input, and illuminates
the FAULT L.E.D. This alerts you to transformer isolate the TX-VLA1 power source from the camera power source.
