Abstract

A method and apparatus for alerting personnel in response to an alarm from an automated system. The monitoring system detects an alarm. Upon detection of the alarm, the monitoring system searches a list. The list includes contact numbers, wherein each contact number has a corresponding contact person, delay time, and a contact day and time for when each contact number should be used. A current day and time is matched with a contact day and time from the list. Upon a successful match, a contact person corresponding to the matched contact day and time is notified using a contact number corresponding to the matched contact day and time. If after a delay time corresponding to the matched contact day and time the alarm is not reset, a next contact number from the list having a contact day and time matching the current day and time is used to notify a contact person corresponding to the next contact day and time. A next contact number is selected and used from the list until the alarm is reset.

Claims

1. A method for alerting personnel in response to an alarm signal from an automated system, comprising the steps of:

a. receiving the alarm;

b. searching a list of contact numbers, wherein each contact number has a corresponding contact person, delay time, and a contact day and time for when each contact number should be used;

c. matching a current day and time with a contact day and time from said list;

d. notifying a contact person corresponding to said matched contact day and time using a contact number corresponding to said matched day and time;

e. determining whether the alarm has been reset within a delay time corresponding to said matched contact day and time, and if not, repeating steps (c)(e) using a next contact number from said list having a contact day and time that matches said current day and time.

2. The method of claim 1, wherein said list has a first contact number and a last contact number, and if said last contact number is used and the alarm is not reset, said next number becomes said first contact number.

3. The method of claim 2, wherein the system is attended.

4. The method of claim 3, wherein said contact person notified using a contact number corresponding to at least one of a group comprising a pager number, residential telephone number, office telephone number and mobile telephone number.

5. The method of claim 3, wherein said unattended system is a telecommunications switch.

6. A method for alerting personnel in response to an alarm from an automated system, comprising the steps of:

a. ordering a list of contact numbers for contact personnel by a contact day and time for when each number should be used;

b. detecting the alarm;

c. selecting a contact number from said list;

d. notifying a contact person using said contact number;

e. determining whether the alarm has been reset within a delay time corresponding to said selected contact number, and if not, repeating steps (c)-(e) sing a next contact number from said list.

7. The method of claim 6, wherein said list has a first contact number and a last contact number, and if said last contact number is used and the alarm is not reset, said next number becomes said first contact number.

8. The method of claim 7, wherein the system is unattended.

9. The method of claim 8, wherein said contact person notified using a contact number corresponding to at least one of a group comprising a pager number, residential telephone number, office telephone number and mobile telephone number.

10. The method of claim 9, wherein said delay time may vary for each contact number.

11. The method of claim 10, wherein said unattended system is a telecommunications switch.

12. An apparatus for alerting personnel in response to an alarm generated by a monitoring system responsible for monitoring an automated system, comprising:

an alarm alerting device coupled to the monitoring system for receiving the alarm, said alarm alerting device selecting a contact number for a contact person corresponding to a day and time when said contact person is likely to be found;

a communications facility connected to said alarm alerting device for notifying said contact person using said selected contact number; and

a subscriber unit for receiving said notification from said alarm alerting device via said communications facility.

13. The apparatus of claim 12, wherein said alarm alerting device comprises:

memory storing a list having contact numbers, wherein each contact number has a corresponding contact person, delay time, and a contact day and time for when each contact number should be used;

a system clock for determining a current day and time; and

a comparator for comparing said current day and time with a contact day and time from said list, and selecting said compared contact day and time if it matches said current day and time.

14. The apparatus of claim 13, wherein said alarm alerting device further comprises a timer coupled to said system clock, wherein if said timer reaches a delay time corresponding to said selected contact number and the alarm has not been reset, said comparator selects a next contact day and time matching said current day and time, and a next contact number corresponding to said next contact day and time are used by said communication facility to notify a contact person corresponding to said next contact day and time.

15. The apparatus of claim 14, wherein said list has a first contact number and a last contact number, and if said last contact number is used and the alarm is not reset, said next contact number becomes said first contact number.

16. The apparatus of claim 15, wherein the system is unattended.

17. The apparatus of claim 16, wherein said subscriber unit corresponds to at least one of a group comprising a pager, residential telephone, office telephone and mobile telephone.

18. The apparatus of claim 17, wherein said delay time may vary for each contact number.

19. The apparatus of claim 18, wherein said unattended system is a telecommunications switch.

20. A method for alerting personnel in response to an alarm signal from an automated system, comprising the steps of:

a. receiving the alarm;

b. selecting a contact number from a list of contact numbers, wherein each contact number has a corresponding contact person and delay time;

c. notifying a contact person corresponding to said selected contact number using said selected contact number;

d. determining whether the alarm has been reset within a delay time corresponding to said contact number, and if not, repeating steps (b)-(d) using a next contact number from said list.

21. The method of claim 20, wherein said list has a first contact number and a last contact number, and if said last contact number is used and the alarm is not reset, said next number becomes said first contact number.
