Definitions
- the invention relates to two methods for checking the transport time of an aspirating smoke detector with the help of a user.
- Room air containing smoke and/or fire gas to be detected is sucked in via an intake pipe connected to a fire detector unit of the aspirating smoke detector in order to determine a fire parameter by measurement.
- the intake pipe has several distributed intake openings between the fire detector unit and a remote pipe end.
- Such aspirating smoke detectors are also referred to in technical terms as ASD (for Aspirated Smoke Detector).
- the invention further relates to a (first) aspirating smoke detector with at least one aspirating/detector unit.
- the latter has a fire detector unit for the metrological determination of a fire parameter and a suction unit upstream or downstream of the fire detector unit in the suction direction.
- the suction unit is in particular a fan. It can also be a pump.
- the aspirating smoke detector further comprises an aspirating pipe connected to the aspirating/detector unit for sucking in room air with smoke and/or fire gas to be detected.
- the aspirating pipe has several distributed suction openings between the aspirating/detector unit and a remote pipe end.
- the aspirating smoke detector further comprises a data interface, such as a radio data interface, and an (electronic) control unit connected to the fire detector unit and to the data interface.
- the control unit preferably a microcontroller, is set up or programmed to issue a fire alarm, preferably at the data interface, in particular in the event of a fire being detected.
- the fire alarm can be, for example, at the
- the fire alarm can be output directly from the suction/detector unit, e.g. by means of a flashing or permanently lit LED.
- the fire alarm can alternatively or additionally be output on a display on the suction/detector unit. It can also alternatively or additionally be output acoustically, e.g. via a connected loudspeaker or via a connected horn.
- the fire alarm can alternatively or additionally be output via the data interface, either wired or wirelessly, to a higher-level fire alarm control center.
- the invention further relates to a (second) aspirating smoke detector which, in comparison to the (first) aspirating smoke detector, also has a first logical clock, in particular a real-time clock, as well as a control unit connected to the fire detector unit, to the data interface and to the first logical clock.
- the latter is in turn designed to issue a fire alarm at the data interface in the event of a fire being detected.
- the invention further relates to a computer program, in particular a test application for execution on a microprocessor of a mobile communication terminal, in particular on a smartphone.
- the invention relates to a mobile communication terminal, in particular a smartphone, comprising at least one microprocessor for executing such a computer program loaded into a non-volatile memory or a flash memory of the communication terminal.
- a method and a device for detecting and locating fire sources in at least one monitoring room are known.
- An air sample representing the room air of the individual monitoring rooms is taken from each of the monitoring rooms via a common intake pipe system.
- At least one fire parameter is detected in the air samples sucked in via the intake pipe system using a detector for detecting fire parameters.
- the sucked-in air samples located in the intake pipe system are blown out using a blow-out device or suction/blowing device. Air samples are sucked in again from the individual monitoring rooms via the intake pipe system, at least until the detector again detects a fire parameter in an air sample.
- the running time until the fire parameter is detected again is evaluated during the new air sample taking that has already been carried out, in order to locate the location of an emerging or existing fire in one of the many monitoring rooms. Finally, a signal is emitted which indicates the emergence and/or presence of a fire in at least one of the monitoring rooms.
- the device has a smoke generator which is arranged at an intake opening and which can artificially generate a fire parameter for setting and checking the fire detection device.
- a smoke generator which is arranged at an intake opening and which can artificially generate a fire parameter for setting and checking the fire detection device.
- An aspirating smoke detector uses the intake pipe to extract air samples from rooms and feed them to the fire detector unit.
- the intake pipes can extend over several hundred metres, for example in a range of 100 metres to 1000 metres. Any smoke or fire gases sucked in must therefore be detected along their entire length up to the fire detector unit.
- the time required for this is also referred to as the transport time or dead time.
- This transport time is typically related to the time required from the entry of smoke or fire gases at the intake opening furthest from the fire detector unit, i.e. at the far end of the intake pipe, to detection in the fire detector unit.
- the transport time can be in the range of minutes.
- the maximum transport time for a pipe length of 200 m, an average flow velocity of 1 m/s and smoke suction at a pipe end furthest from the fire detector unit is around 200 seconds.
- the intake pipes can become dirty over time. They can also become leaky, which leads to the smoke particles being sucked in becoming diluted with the ambient air. Both of these things increase the transport time and cause a delay in the fire alarm being issued. Periodic checks therefore include checking the air volume flow or measuring the transport time.
- a test fluid in particular a smoke aerosol
- Both service technicians must act synchronously, i.e. the first technician applies the test fluid to the furthest suction hole at a time tl and notes this time.
- the second technician at the ASD notes the time of the alarm t2.
- the resulting transport time is then the time difference t2 minus tl.
- This procedure is time-consuming and expensive due to the personnel involved. Furthermore, this procedure contains sources of error: The times recorded by the technicians are may be inaccurate because the technicians' clocks are not synchronized or incorrect times are recorded.
- the user connects to the aspirating smoke detector using a mobile terminal via a radio data connection.
- the mobile terminal or the mobile communication terminal is in particular a smartphone, such as an iPhone® or an Android smartphone. Alternatively or additionally, it can be a tablet or a notebook.
- the latter has a radio data interface.
- the aspirating smoke detector Upon receipt of a user input from the mobile device, the aspirating smoke detector switches from an operating mode to a test mode to check the transport time.
- a test fluid is dispensed by the same user into or at one of the intake openings at the remote end of the pipe.
- the time period measured by the aspirating smoke detector between the received user input and the detection of the test fluid in the fire detector unit is determined as the transport time and is calculated by the Aspirating smoke detectors transmit data to the mobile device via the radio data connection.
- the aspirating smoke detector transmits a detection signal via the radio data connection to the mobile device to determine the transport time through the mobile device.
- the detection signal is typically emitted by the aspirating smoke detector when a minimum level, such as a minimum smoke level, for fire detection is exceeded in the fire detector unit set up to measure a fire parameter.
- the test fluid is preferably a test aerosol or a test gas, such as carbon monoxide (CO).
- At least approximately at the same time is meant a time period between the input of a user to start the method according to the invention for checking the transport time by pressing a button or a corresponding softkey on the mobile device and the dispensing of the test fluid, typically by the same user.
- the test fluid is usually dispensed by pressing a spray head on a pressurized spray can containing the test fluid. This time period is in a range of less than 3 seconds, in particular less than 2 seconds and preferably less than 1.5 seconds.
- the transmission time between pressing the button or softkey on the mobile device (user input) and receiving the user input by the aspirating smoke detector via an existing radio data connection is negligible and typically less than 1 second.
- the particular advantage of the method according to the invention for checking the transport time is that, on the one hand, no stationary smoke or test fluid generator is required. On the other hand, only a single service technician is required to carry out the inspection of the aspirating smoke detector, which is also more reliable and precise.
- the determined transport time is output on the mobile device, in particular on the user's mobile device. This advantageously enables the user to evaluate the transmitted transport time on site.
- a test result determined by the aspirating smoke detector is transmitted from the aspirating smoke detector via the radio data connection to the mobile device for output to the user, in particular of the mobile device, by comparing the measured transport time with a reference time stored in the aspirating smoke detector or received from the mobile device.
- the reference time is preferably a transport time of the aspirating smoke detector determined by measurement during proper operation of the aspirating smoke detector. Alternatively, it can be a reference time simulated in terms of flow.
- the test result is determined by forming the difference between the measured transport time and the reference time stored in the aspirating smoke detector or in the mobile device.
- a test result determined by the mobile device is output to the user, in particular of the mobile device, on the mobile device by comparing the transport time received from the aspirating smoke detector with a reference time stored in the mobile device or received from the aspirating smoke detector.
- the mobile device determines a time period between the user input on the mobile device and the reception of the detection signal by the Aspirating smoke detector determines the transport time.
- a test result determined by the mobile device is then output to the user on the mobile device by comparing the determined transport time with a reference time stored in the mobile device or received from the aspirating smoke detector.
- the test result is displayed in the simplest case on a display of the mobile device.
- it can be displayed acoustically, such as by a voice message or an acoustic signal, or haptically, such as by a vibration, on the mobile device.
- a pass message is preferably issued as the test result on the mobile device if the measured or determined transport time falls short of a predetermined reference time.
- This can, for example, be a text or voice output on the mobile device with the content «OK», «Test passed» or a corresponding symbol such as «thumbs up».
- a fail message is preferably issued as the test result on the mobile device. This can, for example, be a text or voice output on the mobile device with the content «Not OK», «Test failed» or a corresponding symbol such as «thumbs down».
- the object of the invention is further achieved by a second method according to the invention, in which the user connects to the aspirating smoke detector with a mobile terminal via a radio data connection in order to synchronize a first logical clock of the aspirating smoke detector with a second logical clock of the mobile terminal.
- the first logical clock is typically a real-time clock that more or less corresponds to the physical time of a locally applicable or assigned world time zone. However, the first logical clock can deviate from the relevant physical time by up to several minutes over the operating time of an aspirating smoke detector.
- a test fluid is dispensed by the same user into or at one of the intake openings at the remote end of the intake pipe. After dispensing the test fluid and the user input to save a current start time, the user can return to the intake/detector unit.
- the transport time is determined as a time difference between an alarm time stored in the aspirating smoke detector and read out by the user via the radio data connection and the start time stored in the mobile device and is displayed on the mobile device for evaluation by the user.
- the alarm time is already stored after the test fluid has been detected by the fire detector unit before the user reaches the aspirating/detector unit again after the test fluid has been dispensed at the far end of the pipe. This method of checking the transport time is particularly simple and quick.
- the time difference advantageously corresponds exactly to the transport time to be checked, apart from the short time span between the application of the test fluid and the pressing of a start button on the mobile device.
- This time span is in a range of less than 3 seconds, in particular less than 2 seconds and preferably less than 1.5 seconds.
- the mobile device and the aspirating smoke detector are connected to one another directly or indirectly via a radio data connection, in particular via an IP radio data connection.
- the radio data connection is based in particular on a mobile radio standard, such as a 4G or 5G standard, a WLAN standard or a Bluetooth standard.
- the radio data connection can be based on an NFC, ZigBee or Thread standard.
- the aspirating smoke detector is connected to a higher-level fire alarm control panel via a detector bus.
- the aspirating smoke detector can be connected to the fire alarm control panel via a wired or wireless detector bus.
- the fire alarm control panel is connected to a cloud infrastructure or to a web server via an IP data connection.
- the mobile device is connected to the fire alarm control panel as a router via a WLAN or mobile data connection to the cloud infrastructure or the web server.
- the output of a possible fire alarm is suppressed in test mode, in particular for a predeterminable suppression time.
- the latter is in a time range of 1 minute to 20 minutes, in particular in a range of 5 minutes to 15 minutes.
- the object of the invention is further achieved by a first aspirating smoke detector whose control unit is set up or programmed to connect the data interface to the Receipt of a user input to check the transport time.
- the control unit is further configured to switch from an operating mode to a test mode upon receipt of the user input.

- the control unit is further configured to output a failure message as a test result at the data interface of the aspirating smoke detector in the other case.

- the control unit of the aspirating smoke detector is set up to only output the measured transport time or the detection signal at the radio data interface and/or to receive a valid reference time from the radio data interface if a connection establishment between the radio data interface and a communication device connected or coupled to it, in particular with a mobile terminal, has been authorized by the control unit of the aspirating smoke detector. This advantageously increases security against unauthorized access to the aspirating smoke detector by third parties.
- Authorization can be carried out, for example, by the mobile terminal transmitting a valid identifier, if necessary with login data and password, to the control unit of the aspirating smoke detector via the radio data interface.
- the control unit is set up accordingly to check the aforementioned identifier and, if necessary, the login data and password.
- control unit is designed to switch from the test mode back to the operating mode of the aspirating smoke detector if the control unit receives a deregistration of a communication device, in particular the mobile terminal, from the radio data interface or if the control unit detects the interruption of an already established radio data connection with the communication device for a minimum period of time.
