ABSTRACT:
A contactless ambient condition detection system includes at least one base connectable to a power and signal transmitting cable and a compatible detector. The detector removably engages the base. Electrical energy, from the cable is wirelessly coupled to the detector via the base. The detector is in wireless bidirectional communication with the base. Alarm indicating signals, generated remotely, can be wirelessly coupled, from the cable via the base, to the detector. Locally generated alarms can be wirelessly coupled to the cable. Detectors can be replaced without exposing the installer to AC contacts.
