SECURITY SYSTEM WITH MULTIPLE LEVEL OF ACCESS ABSTRACT A security system is provided with multiple levels of access in which a higher level pass code gives the user access to numerous system functions, such as disarming of the system, resetting, system testing, loop by-passing, and system programming, whereas a lower level pass code gives the user access to less functions, in one embodiment to disarming only a portion of the system. In one embodiment, an eraseable memory is programmed with a number representing a temporary pass code after the entry of a higher order pass code by the individual setting the temporary pass code. The permanent pass code may be made more complex than the temporary pass code to provide an extra level of security by providing that the permanent pass code have more digit. Timing circuitry is provided to establish a temporary pass code entry window during which a temporary pass code may be entered into the eraseable memory. No entry of a temporary pass code within the alloted time results in a disabling of the temporary pass code system.
