A regional monitoring system includes wireless units, or detectors which can be associated with a displaced regional monitoring control element. Local feedback provided at the unit or detector for the installer. The units, or detectors can include all devices which can usefully be coupled to the monitoring control element. Examples, without limitation include all types of ambient condition detectors, motion detectors, location detectors, glass break detectors and the like. A light emitting diode carried by a respective unit can be activated to output a selected color when the unit has been successfully enrolled, and in communication with the monitoring control element.
