Abstract

A fire detection system (10) for a building is disclosed which comprises a fire panel (12), a loop (16), and a plurality of fire detectors (14) on the loop. Each fire detector includes a transponder which enables the fire detector to communicate with asset tags (20) on assets (18.1, 18.2) distributed in the building. The tags can communicate with a number of tarnsponders whereby the tags'"'"' position in the building can be tracked.

Claims

1. A fire detection system which comprises a control panel, a plurality of distributed fire detectors, a communications network via which communication between the detectors and the control panel can take place, and an asset tagging transponder which is also linked to the control panel via said communications network.

2. A fire detector system as claimed in claim 1, wherein said asset tagging transponder is built in part of, or otherwise associated with, one of the fire detectors.

3. A fire detection system as claimed in claim 2, and which comprises a plurality of asset tagging transponders, each of said transponders being a built-in part of, or otherwise associated with, a corresponding one of the fire detectors.

4. A fire detection system as claimed in claim 1, and including a plurality of asset tags each of which includes means for establishing a radio frequency communications link with said transponder.

5. A fire detection system as claimed in claim 3, and including a plurality of asset tags each of which includes means for establishing a radio frequency communications link with at least one of said transponders.

6. A fire detection system as claimed in claim 5, wherein each asset tag includes means for establishing a radio frequency communications link with a plurality of said transponders whereby said transponders can track the location of the asset with which the tag is associated.

7. A fire detector which includes an asset tagging transponder.

8. A kit which comprises a fire detector including an asset tagging transponder, and one or more asset tags, the asset tagging transponder being capable of communicating with the (or each) asset tag over a radio frequency communications link.

9. A fire detection system which comprises a control panel, a plurality of fire detectors distributed in the building which is to be protected, each fire detector incorporating an asset tagging transponder, a hard wired communications link between the fire detectors and the control panel over which communications between the panel and detectors can take place, and a plurality of asset tags on assets distributed in said building, each asset tag being in radio frequency communication with one of said transponders.

10. A system as claimed in claim 9, wherein each asset tag include means for enabling it to communicate with two or more transponders whereby the transponders can track the location of assets in said premises.
