A method of commissioning or maintenance an alarm system is provided. The method including: receiving a fault report including one or more faults from an alarm system; categorizing the one or more faults; prioritizing the one or more faults into a list of highest priority; determining a first root cause of a first fault of the one or more faults in response to at least one of an alarm system configuration of the alarm system, a device mapping of the alarm system, and an event history of the alarm system; providing instructions, via a user interface, regarding how to resolve the first fault in response to the first root cause; and detecting whether the first fault is resolved.

A short-circuit isolator includes a switch configured to selectively interrupt an electrical circuit connected to the short-circuit isolator. The short-circuit isolator is configured to cause the switch to interrupt the electrical circuit when a current at the short-circuit isolator exceeds a current threshold and at least one of a voltage at the short-circuit isolator is below a voltage threshold or a resistance of the electrical circuit measured at the short-circuit isolator is below a resistance threshold.

A fire detector is connected to a loop transmission line connected to a receiver. When the loop transmission line is normal, a transmission unit is connected to the fire detector. When a disconnection failure occurs, a disconnection monitoring unit turns on switching circuits to connect the end of the loop transmission line to the transmission unit, and the receiver connects to the fire detector from both ends of the loop transmission line. An input/output switching booster is inserted and connected in the middle of the loop transmission line, and when the start side transmission line is disconnected and the switching circuits are turned on, the input/output is switched. Accordingly, the input/output switching booster amplifies the down signal input from the terminal side transmission line and outputs it to the start side transmission line and at the same time amplifies the up signal input from the start side transmission line.

A patient monitoring hub can communicate bidirectionally with external devices such as a board-in-cable or a dongle. Medical data can be communicated from the patient monitoring hub to the external devices to cause the external devices to initiate actions. For example, an external device can perform calculations based on data received from the patient monitoring hub, or take other actions (for example, creating a new patient profile, resetting baseline values for algorithms, calibrating algorithms, etc.). The external device can also communicate display characteristics associated with its data to the monitoring hub. The monitoring hub can calculate a set of options for combined layouts corresponding to different external devices or parameters. A display option may be selected for arranging a display screen estate on the monitoring hub.

A method and apparatus for electrical line testing. The method and apparatus provides audio, visual and/or electronic information to indicate electricity is flowing or not flowing through an electrical circuit controlled by a remote circuit breaker. The method and system help identify which electrical sockets are controlled by which remote circuit breakers. The method and apparatus is used over short distances in a residential home or over long distances in a commercial building such as a warehouse or factory. The method and apparatus is also used via a cloud communications network and with smart speakers. The method and apparatus is used with or without an external network devices such as a smartphone, electronic tablet, wearable device, etc.

A resistor-capacitor (RC) sensor circuit includes an integration capacitor configured to integrate a representative copy of a current that drives an electronic circuit line. The integration capacitor is configured to integrate over a first time period to generate a first representative voltage and over a second time period to generate a second representative voltage. The RC sensor circuit includes a sampling circuit coupled to the integration capacitor and configured to sample the first representative voltage and the second representative voltage. A ratio of the first sampled voltage and the second sampled voltage is indicative of an RC time constant of the electronic circuit line.

A method for dynamically partitioning a security system is described. A security system identifies sensors registered with the security system. The security system then identifies a first partition attribute of a first group of sensors of the sensors. The first partition attribute indicates a primary partition of the security system. The security system then identifies a second partition attribute of a second group of sensors of the sensors. The second partition attribute indicates a secondary partition of the security system. The security system forms a dynamic partition of the security system based on a combination of the first and second partition attributes.
