A method, apparatus and system for maximizing transmission power levels in wireless security systems wherein the transmitted power is adjusted depending on the type of signal being transmitted in order to comply with power level restrictions imposed by agency regulations (e.g. Federal Communications Commission). Higher priority control signals messages are transmitted at the maximum permitted or normal output power level and are not compromised by the requirement for transmission of data signals that are transmitted at a reduced power level. In addition, a method and apparatus for reducing a required quantity of data signal transmissions in wireless security systems is provided, wherein data signals are exclusively transmitted at a reduced power level during an installation mode leaving only control signals to be transmitted at normal power during normal operation mode. Data information contained in the data signal is stored in a console during installation mode, and retrieved and displayed to the user in response to the control signal during normal operation mode. The reduction in data signal transmissions reduces on-air time, thereby reducing the potential for message clash.
