The present invention discloses a CO alarm for a battery type generator, comprising a MCU control unit U2, configured to analyze and process signals, which is in a deep sleep state when the generator is not running, and enters a sleep plus timing wake-up working state after the engine is running; a CO sensor detection unit U3 connected to the MCU control unit, configured to convert the CO concentration in the environment into a corresponding electrical signal and output to the MCU control unit U2 for processing; an alarm indication unit U4 connected to the MCU control unit, configured to give an alarm prompt for the CO concentration and an alarm failure prompt.

Methods, devices, and systems for an unmanned system (US) for safety device testing are described herein. In some examples, one or more embodiments include a processor and a memory having instructions stored thereon which, when executed by the processor, cause the processor to capture, using an imaging device of the US, an image of a safety device, determine information corresponding to the safety device based on the image, communicate the determined information to a fire system network, receive, from the fire system network, a test procedure associated with the safety device, perform the test procedure on the safety device, and communicate a result of the test procedure to the fire system network.

A chamberless smoke detector includes at least one light emitter and at least one light receiver and a transparent sheet above the at least one light emitter and the at least one light receiver.

Aspects of the invention are directed towards an apparatus and method for executing operation/s on device/s. One or more embodiments of the invention describe the method comprising steps of receiving a voice command from a user for enabling one or more devices to execute an operation and determining validity of the voice command received from the user. The method further describes steps of converting the voice command to a generic command based on the validity of the command and transmitting the generic command for enabling the one or more devices to execute the operation.

The present disclosure relates to aspirating smoke detectors (ASD). In an ASD, ambient air is aspirated and is fed to a fire detector unit for determining a signal level. For normal operation, the suction power is set to a nominal airflow value and this is increased from a minimum signal level value in order to shorten the transport time of aspirated smoke through the suction pipe to the fire detector unit. In some embodiments, an interruption signal provided for normal operation is output if the airflow exceeds an upper limit value for a minimum period. Independently thereof, the suction power is increased from the minimum signal level value only to the extent that the airflow does not exceed the upper limit value. Or, regardless thereof, the suction power is increased only for a timespan smaller than the minimum period in which the airflow exceeds the upper limit value.

The monitoring system includes a support device which is displaceable, a mast which is supported by the support device, and a stabilization device configured to vertically stabilize the mast during displacements of the support device, the stabilization device including a plurality of support arms which are fastened to the mast and which are angularly offset from each other, and a plurality of air flow generation devices that are fastened to the support arms.

An aspirating detection system for detecting a fire event in a monitored environment, a method of determining when an aspirator for an aspirating detection system requires maintenance, and a method of calibrating a control module for an aspirating detection system. The aspirating detection system (1) includes an aspirator (2) for sampling air from the monitored environment (100), and a vibration sensor (3) configured to monitor a vibration signature of the aspirator (2). The aspirating detection system (1) may further include a control module (4) in communication with the vibration sensor (3). The control module (4) may be configured to determine if the aspirator (2) requires maintenance based on the vibration signature of the aspirator (2).

Devices, methods, and systems for infrastructure-less indoor navigation in a fire control system are described herein. One device includes a non-transitory computer readable medium having computer readable instructions stored thereon that are executable by a processor to receive a location of each of a plurality of smoke detectors of a facility, display the location of each of the plurality of smoke detectors in a building information model (BIM) on a user interface, wherein each respective one of the displayed plurality of smoke detectors represents a different smoke detector of the plurality of smoke detectors of the facility, receive a selection of a first displayed smoke detector of the plurality of displayed smoke detectors representing a first smoke detector of the plurality of smoke detectors of the facility, and guide a user to the location of the first smoke detector of the facility responsive to receiving the selection.

A system and method for selecting an algorithm for monitoring alarm conditions based on a detector orientation and position. A method may include determining a position and orientation of a smoke detector, selecting an algorithm for performing detection of an alarm condition, and operating the smoke detector using the selected algorithm.

A method of testing a smoke alarm system including: receiving a first manual input via an input device of a mobile device from a user of the mobile device, the first manual input indicating that the user would like to initiate a test of the smoke alarm system including one or more smoke alarms, the one or more smoke alarms including at least a first smoke alarm; determining a time slot allocation, the time slot allocation indicating when each of the one or more smoke alarms should emit an alarm; transmitting the time slot allocation to each of the one or more smoke alarms, wherein each of the one or more smoke alarms is configured to activate the alarm in accordance with the time slot allocation; activating a first alarm on the first smoke alarm; and receiving a second manual input indicating that the user has heard the first alarm.
