| 1. A wireless access control system adapted to control access to an access point, said system comprising:
a remote reader device fixedly positioned adjacent the access point and operable to read an access signal in a first condition
and inhibited from reading an access signal in a second condition;
a power supply associated with the remote reader device and having an energy level;
a processor monitoring said energy level of said power supply, said processor initiating a warning signal when said energy
level of said power supply is below a first predetermined threshold and transitioning the remote reader device to the second
condition when said energy level of said power supply is below a second non-zero predetermined threshold; and
a transceiver coupled to the power supply and operable to transmit an RF signal indicative of the energy level of the power
supply.
