Abstract
Devices, methods, and systems for extending a fire loop are described herein. An example device for a fire alarm system includes a first communication pathway coupled to a first plurality of fire sensing devices wired in a first loop, a second communication pathway coupled to a second plurality of fire sensing devices wired in a second loop, wherein the second loop is independent of the first loop, and a controller configured to drive the second plurality of fire sensing devices of the second loop and drive the first plurality of fire sensing devices of the first loop during a failure event occurring on the first loop.
Claims20
A device for a fire alarm system, comprising:
- a first communication pathway coupled to a first plurality of fire sensing devices wired in a first loop;
- a second communication pathway coupled to a second plurality of fire sensing devices wired in a second loop, wherein the second loop is independent of the first loop;
- and
- a controller configured to:
- drive the second plurality of fire sensing devices of the second loop;
- and
- drive the first plurality of fire sensing devices of the first loop during a failure event occurring on the first loop.
A fire alarm system, comprising:
- a control panel;
- a first plurality of fire sensing devices wired in a first loop and in communication with the control panel;
- and
- a fire loop extender module in communication with the control panel, the first plurality of fire sensing devices wired in the first loop, and a second plurality of fire sensing devices wired in a second loop, wherein:
- the second loop is independent of the first loop;
- the fire loop extender module is configured to drive the first plurality of fire sensing devices wired in the first loop during a failure of the control panel;
- and
- the fire loop extender module is configured to drive the second plurality of fire sensing devices wired in the second loop.
A method, comprising:
- driving, by a controller of a fire loop extender module, a plurality of fire sensing devices wired in an extended loop;
- determining, by the controller, that a failure event has occurred on a different loop of fire sensing devices;
- and
- driving, by the controller, the fire sensing devices of the different loop while driving the plurality of fire sensing devices wired in the extended loop in response to determining the failure event has occurred.
