Ranger receivers and transmitters are a long range RFID solution.  Ranger transmitters are active and similar to auto remotes in that they have a replaceable watch battery, but they send card IDs. They transmit a card ID to the Ranger receiver up to 100' away.  The Ranger receivers connect directly to access control panels as if they were a card reader.  Ranger setups are ideal for access control applications, including parking gates, vehicle barriers, and touch free automatic doors operators. The transmitters also contain a passive RFID tag internally that allows them to be used on a standard Farpointe proximity reader no matter the state of the battery.  The WRR-22 Receiver has multiple outputs (2) that allow it to act as two separate card readers on a standard door controller.  Each button group on the transmitter is assigned to a reader output.
