The Gemini GEMC-RECV RF Receiver is the hardwired interface to Napco's Wireless-Ready FIREWOLF C-Series control panels (see WI1653 for installation instructions). The wireless system is comprised of a compatible GEMC-Series control panel, at least one GEMCRECV receiver, and one or more companion GEMCSeries (Commercial) or GEM-Series (Residential Fire or Burglary only) transmitters. The transmitters may be wireless smoke detectors, space-protection devices, window/door sensors, or other listed devices that report zone status and supervision information to the receiver without the use of wires.
