Various arrangements for handling delayed status update are presented. A network-enabled sensor unit may be used to measure an environmental condition. The sensor unit may determine, based on measuring the environmental condition, an environmental condition status has changed state. A network connection may be established that permits communication with a remote notification service system. This notification service system may maintain a remote status intended to be synchronized with the environmental condition status of the sensor unit. The sensor unit may determine that the environmental condition status has changed prior to communicating the environmental condition status to the notification service system. A historical status array may be transmitted to the notification service system in response to determining the environmental condition status has reverted to the first state prior to communicating the environmental condition status. The historical status array can indicate previous states of the environmental condition status of the sensor unit.

An apparatus, operations controller and methods for controlling unmanned aerial vehicles for detection, prevention and suppression of fires in a designated zone are presented. Monitored information is received and analyzed to detect a presence of a fire event or a fire risk in the designated zone. A cargo unmanned aerial vehicle is directed to a vicinity of the fire event or the fire risk and instructed to deploy a fire retardant or a fire suppressant at a location of the fire event or the fire risk, if the presence of the fire event or the fire risk is detected.

There is provided networks, systems and displays for providing derived data and predictive information for use in emergencies; and in particular for use in wildfire emergencies. More particularly, there is provided systems, equipment and networks for the monitoring and collecting of raw data regarding fire emergencies, both real time and historic. In embodiments, this raw data is then analyzed to provide derived data, predictive data, virtual data, and combinations and variations of this data, which depending upon the nature of this data may be packaged, distributed, displayed and used in various setting and applications to mitigate, avoid and manage the emergency, including a wildfire emergency.

The present disclosure generally relates to the field of fire alarms. The teachings thereof may be embodied in a strobe notification appliance having: a boost circuit connected to an input voltage; an energy storage circuit charged by the boost circuit; a drive circuit generating a drive current; an LED circuit with at least one LED element; a first sampling circuit collecting an overall voltage drop of all the LED elements; and a control circuit configured to adjust the drive circuit to supply a working current during an alarming stage and supply a detection current during a detection stage. The detection current is lower than the working current and thereby light energy produced by the LED elements during the detection stage is lower than alarming light energy produced during the alarming stage. During the detection stage, the control circuit determines whether the LED circuit works normally based on the collected overall voltage drop.

A component 10 for use in an alarm system includes a component controller 12 and an offline configuration module 14. The offline configuration module 14 includes a passive RFID tag and is configured to receive and store an indication of at least one configuration parameter wirelessly transmitted to the configuration module. Upon initialisation of the component 10, the component controller 12 operates the component 10 in accordance with one or more protocol determined by the at least one configuration parameter indicated by the indication stored by the offline configuration module 14.

A smoke detector includes a tamper indicator that can prevent a cover from at least partially covering a battery location and/or mounting of a detector body to a detector mount if a battery is not located at the battery location of the detector body. The detector mount and/or cover can engage with the detector body by relative rotation about an engagement axis, and the tamper indicator can pivot about a pivot axis that is parallel to the engagement axis and/or move along a linear path. The tamper indicator can prevent engagement of a portion of the detector mount, such as an intermediate component between the detector body and a base of the detector mount, with the detector body. The intermediate component can at least partially cover the battery location when engaged with the detector body. The base of the detector mount can engage with the detector body via the intermediate component.

Methods and devices are disclosed for monitoring environmental conditions in one or more environments. In one embodiment, the method includes maintaining a plurality of environmental-condition thresholds, each of which corresponds to an environmental condition and is predetermined based on data corresponding to the environmental condition that is received from a plurality of robots. The method further includes receiving from a first robot first data corresponding to a first environmental condition in a first environment. The method may still further include making a first comparison of the first data and a first environmental-condition threshold corresponding to the first environmental condition and, based on the first comparison, triggering a notification. Triggering the notification may comprise transmitting to the robot instructions to transmit the notification to at least one of a call center and a remote device.

The disclosed technology uses signaling devices and sensors that are distributed throughout a building in order to provide egress guidance to people located in a building when an emergency occurs. Such signaling devices can be located at or near doors, windows, and/or other junction points between different parts of a building (e.g., passageways between different rooms). Signaling devices can provide audio and/or visual information to people to guide them along a safe pathway that is selected to provide safe egress for the person, including anticipating and protecting the person from changing emergency conditions within the building.
