Wireless access control brings flexibility and lower expense to applications such as elevators, remote gates and remote buildings. Making wireless waves is Recognition Source, a supplier of wireless machine-to-machine data communication. Located in St. Charles, Ill., Recognition Source works with systems manufacturers serving the electronic security industry. Its approach is to provide wireless communications and user authentication using encoded card, biometrics and smart card technologies. The WRI-100 can be implemented without expensive traveling cables or trenching wiring and is compatible with any pre-existing hardware. Any Wiegand compatible reader can now be made wireless with the addition of the WRI-100, according to CEO Fred Conforti. The module facilitates secure 900 MHz spread spectrum communications between a remote access point and an access control panel using a Panel Interface Module. The two units work together to transmit and receive signals that are compatible to any panel. What the firm calls Wyreless Access eliminates installation costs that normally include expensive reader-to-panel wiring associated with such applications as remote gates and elevator shafts. With the WRI-100, an end user can choose a reader or keypad and communicate with Wiegand, magnetic stripe or RS 485 multi-drop interfaces. The module also has input/outputs for any strike, door position and request-to-exit sensors.
