A pet collar is provided with a collar command unit, which may include a stimulator feature for discouraging undesirable behavior and a sensor for detecting the undesirable behavior. A controller in the collar command unit electronically communicates with the stimulator and the sensor. The collar command unit also includes a receiver for receiving an event signal from a remote device, such as a building occupant protection system or cellular telephone, which is indicative of an emergency situation. When the pet exhibits the undesirable behavior, the controller allows the stimulator to deliver a deterrent stimulus. However, when the event signal is received, the controller overrides the stimulator feature, preventing the delivery of the deterrent stimulus to the pet. Additionally or alternately, the collar may include a transmitter for transmitting a response to the remote device and a tracking chip for tracking the location of the pet during or after the event.

Sensor communication testing is described herein. For example, one or more embodiments include a sensor comprising a wireless transmitter configured to generate a radio-frequency (RF) signal, an RF attenuator configured to direct the RF signal in a pre-determined direction, and a controller configured to receive a self-test command to execute a communication test, send a communication test signal to a sensor panel in response to the self-test command, and receive a communication test response signal from the sensor panel in response to the communication test signal, where the communication test response signal indicates whether the sensor has passed or failed the communication test.

An emergency notification device performs emergency notification to send an emergency notification to a notification center when an urgent event is generated on a vehicle, and test notification to diagnose whether the emergency notification can be performed, through a notification button that is a part of one user interface. This device has a normal mode in which emergency notification can be performed, and a test mode in which test notification can be performed, through an operation of the notification button, as well as a transit mode in which transition from the normal mode to the test mode can be performed with a predetermined vehicle operation in the normal mode as a trigger. The emergency notification device performs informing processing, which differs from mode to mode, through indicators and that are another part of the one user interface.

A method for a single person to fully test the smoke, heat, or carbon monoxide detection and warning functions of each alarm device of an interconnected fire alarm system comprising of two or more compatible interconnected alarm devices such as smoke alarms, heat alarms, or carbon monoxide alarms in any combination and with interconnections and power supplies of any type, the system including interconnected alarm devices with ON and OFF test switches instead of momentary action test switches, and the smoke, heat, or carbon monoxide detection and warning functions of each of the system's interconnected alarm devices are tested by a number of actions and verifications by a single person.

The invention provides a method for testing a hazard detector that includes transmitting a test mode switching signal from a test device to the hazard detector, setting the hazard detector to a test mode, transmitting a first test mode confirmation signal from the hazard detector to a central monitoring unit, transmitting a second test mode confirmation signal from the hazard detector to the test device, processing a hazard condition detected by the hazard detector as a test event, transmitting a test result signal from the hazard detector to the central monitoring unit, the hazard detector outputting a test completion signal, and setting the hazard detector to a detection mode. The invention further provides a hazard monitoring system, a hazard detector, and a test device.

An apparatus and method for detection and adaption to an end-of-line resistor in a notification appliance circuit (NAC) of a control panel or power booster of, for example, an alarm system, and for ground fault localization in the alarm system are provided. The apparatus can include the NAC where the NAC includes first and second analog input terminals, where the NAC includes first and second external output terminals, and where the NAC includes an end-of-line resistor. Current can be driven through the NAC via the first and second analog input terminals, and voltage can be measured at each of the first and second external output terminals. The measured voltage can be indicative of one of a value of the end-of-line resistor or that a state of the NAC is one of open, shorted, ground faulted, or normal.

The present disclosure relates to methods and devices in clustered alarm scenarios. More particularly the disclosure pertains to methods and arrangements for detecting several messages of a preconfigured message type, arriving sequentially in time. This disclosure proposes a method, performed in a radio network node, of detecting several messages of a preconfigured message type. The method comprises detecting S1 a first message of the preconfigured message type, the first message being associated with an event. The method further comprises reconfiguring S3, in the radio network node, in response to the detection, at least one radio setting related to detecting further messages of the preconfigured message type and monitoring S4 a radio spectrum for further messages of the preconfigured message type using the reconfigured radio settings.

Supervisory signals from a first wireless security sensor are received at a first supervisory rate that repeatedly confirms that the first wireless security sensor remains operatively coupled to a security system controller. A first security sensor alarm is received from the first wireless security sensor and in response, the first supervisory rate is changed to a second, higher, supervisory rate. Supervisory signals are received from the first wireless security sensor at the second supervisory rate that repeatedly confirms that the first wireless security sensor remains operatively coupled to the security system controller. When a second security sensor alarm is received from the first wireless security sensor within a predetermined period of time after the first security sensor alarm, an alarm condition detection alarm is issued from the security system controller.
