Abstract: A security system comprising a plurality of remote wireless units, a central control unit and an adaptive console for translating messages in radio frequency signals into messages in signals suitable for transmission over a wire in order to augment the wireless capability of the system. The adaptive console has a wireless receiver for receiving the radio frequency signal, which includes identification and status information from a wireless remote units. The adaptive console also has a processing unit which translates the identification and status information from the radio frequency signal to corresponding function data derived from a mapping of valid identification and status information to function data, the function data representative of a function to be performed by the security system. The adaptive console also has a transmitter which transmits a signal over a wired connection which includes the corresponding function data to the central control unit or a wired security unit.

Abstract: A method for increasing the dynamic range of the receiver/control unit of an alarm system. The alarm system comprises the receiver/control unit, the receiver comprising at least one antenna apparatus and apparatus for switching the antenna apparatus. The control unit, or processing apparatus, comprises signal detection apparatus and apparatus for controlling the antenna apparatus switching. The method comprises the steps of selecting an input to the receiver, wherein the input maybe an output of one or more antenna apparatus or no antenna apparatus, and detecting the presence of a signal. The basis of the apparatus alarm system is the selection of no antenna, which causes the receiver to be approximately 12 dB less sensitive. The switching of the antenna apparatus is preferably accomplished by processor control of switching diodes.

Abstract: A method for testing the signal margin of an alarm system during installation of the alarm system and during the alarm system supervision time. The alarm system comprises a plurality of remote transmitting devices and a receiver/control unit. The receiver/control unit comprises a receiver with at least one antenna apparatus and processing apparatus for processing messages received from each of the remote devices. Both the install mode and the supervision mode cause the receiver/control unit to receive signals at a lower level than normal by selecting an associated antenna configuration. When entering the installation mode, the processor switches the antenna apparatus to a "no antenna" state, and when entering the supervision mode, the processor switches two or more antenna apparatus to an "on" state.
