A wireless security system having a remote indication device, which operates in a low power mode. The remote indication device provides feedback in the form of a display indicating that a command from a remote control device has been successfully performed or to provide status. The user transmits a first radio frequency signal with a remote control device that is received by a first receiver in the remote indication device during a reduced current mode. The remote indication device then switches to normal current mode, which enables a second receiver, a transmitter, a processing unit and optionally disables the first receiver. The transmitter then retransmits the contents of the first radio frequency signal as a second radio frequency signal to a central control unit via a central receiver. The central control unit then transmits a confirmation or status message back to the remote indication device via a central transmitter in the form of a confirmation radio frequency signal. The remote indication device provides a presentation of the contents of the confirmation radio frequency signal on a presentation unit before returning to the reduced current mode in which the second receiver, transmitter, presentation unit, and processing unit are disabled and the first receiver is enabled. The status is optionally stored in the remote indication device, which enables the status to be re-presented upon request by the user. Alternatively, one receiver may include both the first and second receivers and operate in either the normal operating mode or the reduced power mode. |

DETAILED DESCRIPTION In accordance with the present invention a method provides status to a user in wireless communication systems which comprises the steps of receiving a first radio frequency signal while operating in a reduced power mode, switching from a reduced power mode to a normal operating mode, transmitting a second radio frequency signal comprising data representative of data comprised in the first radio frequency signal while operating in the normal operating mode, receiving a confirmation radio frequency signal while operating in the normal operating mode, presenting the status data to the user, and switching from the normal operating mode to the reduced power mode after a predetermined time has expired. The confirmation radio frequency signal is transmitted in response to receipt of the second radio frequency signal and includes status in response to the second radio frequency signal. In further accordance with the method of the present invention the status data may be stored for a timeout period; and re-presented to the user in response to receipt of a another transmission of the first radio frequency signal prior to lapse of the timeout period. Identification information may be included in the radio frequency signals representing the source of the particular radio frequency signal. In accordance with the present invention a remote indication device is provided which comprises a radio frequency receiver adapted to operate in a reduced power mode and a normal operating mode, a transmitter operating in a normal operating mode, a display, and a processor module coupled to the radio frequency receiver, the transmitter, and the display. The processor module is adapted to switch the remote indication device from the reduced power mode to the normal operating mode upon receipt of a first radio frequency signal by the radio frequency receiver while operating in the reduced power mode. The processor module is also adapted to cause the transmitter to transmit a second radio frequency signal comprising data representative of data comprised in the first radio frequency signal
