摘要

A fire detection system may include isolation circuit having an isolation switch coupled with a system line of the fire detection system and configured to isolate a first side of the system line from a second side of the system line. The isolation circuit may also include a controller coupled with the isolation switch. The controller may be configured to detect repetitive, intermittent short circuit activity on the system line and control the isolation switch based on this activity.

說明書

The communications component 112 may communicate with the external devices 20 via one or more communications links 132, which may be one or more of a wired communications link or a wireless communications link. In an example, the communications component 112 may include one or more antennas, processors, modems, radio frequency components, and/or circuitry for communicating via a wireline and/or wirelessly with the detection devices 120 and/or the external devices 20.

The fire detection and alarm panel 110 may also include a controller 114 configured to receive information from the one or more devices 120 and to determine whether to communicate with the external device 20. Suitable examples of the controller 114 may include, but are not limited to, a processor or plurality of processors in communication with a memory storing computer-readable instructions executable by the processor to perform the control functions described herein. For example, based on communications from one or more of the devices 120, the controller 114 may execute instructions for the communications component 112 to alert a local fire or police department, via the external device 20, about a fire or other incident.

While the fire detection and alarm panel 110 is shown in FIG. 1 as being located in a first zone 12a of the building 10, aspects of the present disclosure do not limit a location of the fire detection and alarm system 110 to this location. For example, the fire detection and alarm panel 110 may be located within any zone (e.g., 12a or 12b) of the building 10 or external to the building 10.
