Abstract

Automated systems and methods provide for enhanced management of components of fire safety systems. Components are identified which require action to ensure compliance with a schedule associated with the components. User and/or electronic output is generated that identifies components and required actions, such actions including inspections, functional testing, maintenance and calibration activities. A record of the identified components may be stored in a system log along with maintenance information. The system log may be reviewed against the schedule based on conformance to ordinances or maintenance requirements. Required actions may be annunciated for the identified components, and the system log may be updated to indicate actions performed on system components. Components may be identified that will require action within a predetermined timeframe and an alert or report may be generated for components that are not in compliance with their associated schedule.

7. The method of claim 1, further comprising reviewing the schedules of at least some of the identified components based on conformance with an ordinance or specification.

8. The method of claim 1, wherein the output comprises an electronic service request concerning identified components requiring servicing.

9. The method of claim 1, wherein the output comprises a display concerning the identified components.

10. The method of claim 1, wherein the output comprises a visual or aural annunciation indicative of actions associated with the identified components.

11. The method of claim 1, wherein the output comprises selective illumination of visual annunciators associated with the identified components.

12. The method of claim 1, further comprising updating the system log to indicate actions performed relative to the identified components.

13. The method of claim 1, wherein the schedule comprises information indicative of a predetermined timeframe within which one or more required actions are to be performed for at least some of the identified components.

14. The method of claim 13, further comprising:

updating the system log to indicate actions performed for the identified components; and

generating an alert or report for each of the identified components that has an incomplete action at the expiration of the predetermined timeframe.

15. The method of claim 1, comprising generating an alert or report for the components associated with the system that are not in compliance with their associated schedule.

16. The method of claim 1, wherein the system comprises a system primary node and at least one other node, the method further comprising:

the system primary node querying the at least one other node for a system log update;

the at least one other node responding to the system primary node query by transmitting performed actions for components controlled by the at least one other node; and

updating the system log with each node'"'"'s performed actions prior to identifying which of the plurality of components requires action in compliance with the associated schedule.

17. The method of claim 1, comprising accessing the system from a local or remote location.

18. The method of claim 1, comprising accessing the system from a remote location and generating the output at the remote location.

19. The method of claim 1, comprising storing a service indicator in the system log indicative of a need for inspection, testing or calibration for a new component added to the system.

20. The method of claim 1, wherein the output comprises a report concerning the identified components.

21. A fire/security or other life safety system, the system comprising:

means for storing data at each component of a plurality of components of the system, wherein the data stored on each component relates to scheduling of maintenance tasks to be performed on the respective component;

means for acquiring the data from the plurality of components via a network;

means for maintaining a system log comprising a list of components of the fire safety system, and a record of one or more of inspecting, testing, maintenance, and calibration of the components;
