PBX security system for monitoring security guard tours
First Claim
1. In a PBX serving a plurality of stations which are scanned by a PBX control processor to provide a plurality of various PBX services to each of said PBX stations in response to service requests generated from each of said stations, a method for operating said PBX to provide a guard monitor check-in service comprising the steps of:
- storing one or more guard tour lists containing entries representing a time-ordered sequence of guard check-ins at selected ones of said stations to serve as station checkpoints for one or more concurrently administrable guard tours;
transmitting guard tour selection signals from any of said stations to said control processor to activate a selected one of said guard tours;
generating sequentially a check-in service request at each of said station checkpoints included in the one of said lists associated with said selected guard tour;
verifying in response to said check-in service request that said station checkpoint is one of said stations included in the one of said lists associated with said selected guard tour; and
applying an alarm signal to an alarm unit in response to an interruption of said time-ordered sequence of guard check-ins.

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.

6. A method utilizing a standard PBX having a control processor, which provides PBX services to a plurality of standard PBX stations in response to generated service requests, to provide one or more concurrently administrable guard tours where each guard tour includes PBX station checkpoints and where a guard checks-in at each one of said station checkpoints in a sequential time-referenced manner wherein said method includes the steps of:
-
specifying one or more guard tour lists containing entries representing a time-ordered sequence of guard check-ins at selected one of said stations to serve as said station checkpoints; transmitting guard tour selection signals from any of said stations to said control processor to activate a selected one of said guard tours; generating sequentially a security service request at each of said station checkpoints included in said selected guard tour; scanning, in response to each security service request, said stations serving as station checkpoints to identify the one of said station checkpoints generating said security service request; comparing said identified station checkpoint against the one of said guard tour lists associated with said selected guard tour; and generating, in response to the step of comparing, an alarm when said identified station checkpoint does not match said sequentially time-referenced station checkpoints contained in the one of said guard tour lists associated with said selected guard tour. - View Dependent Claims (7, 8)

9. A method of operating a standard PBX having a control processor, containing a main memory where the control processor controls and administers a plurality of different call processing operations in response to service requests received from a plurality of connected PBX stations, to provide a security guard monitoring service by defining a plurality of independent guard tours concurrently administrable by the control processor where each of the plurality of tours includes selected stations serving as checkpoints, said method comprising the steps of:
-
allocating portions of said main memory to define a plurality of tables each of which lists the check-in procedure for a guard tour where each table is identified by a unique prescribed guard tour code; selecting, in response to a guard tour service request from any of said stations identifying a guard tour code, the one of said tables identified by said guard tour code; and executing said security guard monitoring processing operation according to the check-in procedure defined in said table identified by said guard tour code when a security guard follows said guard check-in procedure. - View Dependent Claims (10, 11, 12, 13)
