In the following settings you can set the threshold and action values for the alerting.
Notifications via SMS and push messages are only available if an AlarmManager is used as the central device. Push messages additionally require an Kentix360 Cloud account.
Sensor: Temperature, Humidity, Dew-point
The settings of the threshold values for temperature, humidity and dew point can be viewed and adjusted. If the measured value leaves the threshold, an alarm is triggered. The temperature hysteresis is 1°C, the humidity hysteresis 1%.
The dew point is calculated from the current room temperature and the relative humidity. If the difference between room temperature and dew point reaches the set value of the dew point hysteresis (2°C standard), the dew point alarm gets triggered. If room temperature and dew point reach the same value, condensation can occur in systems and devices.
Please note that temperature sensors must be calibrated in order to be able to supply as accurate values as possible (How do I calibrate the temperature sensor?).
Sensor: Carbon Monoxide (Early Fire Detection)
Carbon monoxide (CO) is produced during the incomplete combustion of carbonaceous materials. CO fire detectors can detect smouldering fires involving carbonaceous materials at an early stage because CO propagation occurs not only by convection but also by diffusion. CO fire detectors may also be more suitable for applications where other fire detection techniques are prone to false alarms due to dust, steam and kitchen fumes.
The alarm setting for early fire detection or sensitivity can be set between 10% (high sensitivity) and 90% (lower sensitivity) and triggers an alarm when exceeded. This is an early fire detection based on the carbon monoxide concentration in the air. The percentage value indicates the probability of a fire, i.e. it is proportional to the level of the CO concentration. 5-50% = low fire probability, low CO concentration of 10-50ppm (smouldering fire, defective electronic components, early fire stage), 60-90% = higher fire probability, high CO concentration of >100ppm (smouldering fire, rapid onset of fire, advanced fire). The CO measurement is designed for highest sensitivity to detect fires as early as possible. Carbon monoxide concentrations, as they occur in fires, quickly reach values in excess of 1,000ppm and are also detected at a sensitivity of 90%.
The sensitivity for the integrated PIR (passive infrared) motion detector can be adjusted. It detects objects with a temperature difference to the environment of approx. 4°C and larger than approx. 250x400mm. As a sensitivity value for the reliable detection of persons, a value of 30-50% is reasonable. The detection range is approx. 100°.
Observe the Mounting Instructions.
The sensitivity of the internal vibration sensor can be adjusted in three sensitivity levels. If necessary, the vibration sensor can also be completely deactivated. Note that the mounting position may also affect the sensitivity. To avoid false alarms, the sensor should not be installed in vibration-loaded environments.
The three selectable levels are:
|The device reacts only to strong shocks/vibrations||The device reacts to medium shocks/vibrations||The device reacts to weak shocks/vibrations|
The MultiSensor has two configurable alarm inputs. External alarm devices such as leakage sensors, door contacts or fault messages from external devices can be connected to these alarm inputs. Triggering takes place through a potential-free contact. The trigger logic can be set to Open or Closed.
External Alarm Output
External loads or signals can be switched by the switching outputs. An additional adapter (KIO3) is required for use.
Settings for the time after which a triggered alarm is repeated and the maximum number of repetitions. The alarm is sent via the configured notification paths until the alarm is receipted or the maximum number of repetitions is reached. Please note the information about the notification paths at the top of this page.
Alarm Buzzer Time
Determines whether and for how long an acoustic feedback is given in the event of an alarm.
Alarm Relay Time
Specifies the time in seconds how long the switching outputs should trigger in the event of an alarm.
Motion Detection - Arm-Disarm Time
Switching times for time-controlled arming and disarming of the integrated motion detector. For use, a time server (NTP) must be configured in the network settings of the MultiSensor.
