ABSTRACT:
A security system arrangement utilizing a standard PBX for monitoring a plurality of concurrently administrable guard tours. A control processor of the PBX administers the security monitoring processing operation. This processing operation monitors the activities of tour guards as the guards progress through one or more tours. In particular, a programmable memory defines a plurality of tours. Each tour comprises a finite list of sequentially defined checkpoints where each checkpoint is a designated conventional station set of the PBX. A security controller activates the security system by "dialing" the appropriate feature code at a central control facility, such as an attendant console. The security controller than selects one or more the available tours by "dialing" a tour code. Following the selection and activation of a tour, a tour guard "dials" a check-in code at each checkpoint and progresses sequentially through the checkpoints contained in the list comprising the selected tour or tours. The tour guard has an allotted amount of time in which to reach each of the designated checkponts included in the tour sequence. The tour is successfully concluded when the tour guard sequentialy checks-in within the allotted time at each of the designated checkpoints included in a tour. However, if the proper check-in sequence is not followed or if the allotted time period elapses before the tour guard reaches the next checkpoint in the sequence, an alarm is generated to indicate that the tour sequence is disrupted.
