The D-TECT X Repeater can be used to extend the RF range of a D-TECT X detector, or to boost signal in a poor reception area. The D-TECT X Repeater must be placed within 500 metres line of sight between the D-TECT X detector(s) and D-TECT X Receiver(s). The unit will repeat all signals from D-TECT X detectors within range and as such does not require any programming to function.
