Abstract
An alarm system having motion violation sensors (motion or other presence detectors and door and window switches) can have a potential alarm condition be determined to not be a violation of the secured space in response to an authorization code transmitted by a personal device worn by a user. In one embodiment, the personal device transmits an authorization code periodically to bypass sensors in that room for an interval slightly longer than the period between transmissions. In another embodiment, a request for authorization is transmitted in response to a potential alarm condition, in response to which the device transmits the code. In one embodiment, a single authorization code is changed each time the alarm is disarmed, thereby to prevent recordation and subsequent use thereof. Another embodiment responds to plural authorization codes, such as ID numbers of authorized personnel.
