Filter detector or sensor readings

By default, all detector or sensor readings are included on the map and in the list, often resulting in outdated or irrelevant readings that collect in your list and obscure your map. FH Mobile Response provides a variety of filtering tools to narrow the readings down to display only your most crucial readings.

You can also display and filter sensor readings dynamically, so that you can respond to real-time changes in sensor output.

Examples:  A unit is traveling through a suspected area of contamination, taking sensor readings at various locations to map the extent of contamination. When the unit stops, redundant readings from the same point collect and obscure data from other points. You can display only the most recent reading from that point by using the Recent Readings w/ Proximity filter. Several detectors at an incident site are sending sensor data to FH Mobile Response. You can hide older data by using the Latest Readings filter. You can also monitor the readings of each detector in turn by using the Cycle function. You can highlight detectors sending out an alarm signal by using the Latest Reading with Alarm Cycle filter. When a detector enters the alarm state, other detectors are removed from the display, and readings from multiple alarming detectors cycle through their information display. When the alarming detectors return to normal status, the information from non-alarming detectors appears again. An industrial plant has several H2S sensors installed at strategic points across its facility, and has integrated those sensors with FH Mobile Response. To keep track of the current readings of those sensors to help prioritize and direct response efforts, you can combine the Recent Readings with the Filter Sensor Type → H2S. If you click Zoom to All for a map view that includes all of the sensors, you can then watch for warnings or alarms. You can also enable Cycle to automatically move through the filtered list of sensors, displaying the reading values of each in turn.

Note: You must have purchased FH Mobile Response Premium to work with detector and sensor information in FH Mobile Response. For information on upgrading from FH Mobile Response Basic to Premium, contact your FH sales representative.

1. Display the detectors or sensors you want to work with, as described in Display or hide detector and sensor locations on a map.

2. Do one of the following.

   • Choose Go → Tools → Detectors → List / Filters.

   • On the Incident ribbon, in the Detectors section, click List / Filter.

   At the bottom of the interface, the Detector Browser appears, displaying a list of all the detectors or sensors. Each entry may display color-coded status, type, ID, porting information, and a time stamp of the reading, depending on the sensor setup.

   

   The selected sensor or detector reading is highlighted in the Detector Browser, and its location on the map marked with a red push-pin icon.

3. Filter the list of detectors or sensors in one of these ways.

   Both detector and sensor filters

   1. To the right of the list, click Show Filter.

      In the middle of the Detector Browser, a dark gray areas with the Show Sensor Readings From the Last ____ Hours field in it appears.

      

   2. In Show Sensor Readings From the Last ____ Hours, type the number of hours to be used to determine the time span for "recent" readings.

      Tip: To close the gray area in the center of the Detector Browser, click Show Filter again.

   3. To the right of the list, click the icon to the left of Show Filter, then choose one of the following.

      

      Choose this	To do this
      Recent Alarms	Display only the readings from detectors or sensors that have been in an alarm state within the number of hours you specified in the previous step.
      Recent Readings	Display only the readings from detectors or sensors within the number of hours you specified in the previous step, regardless of alarm status.
      Recent Readings w/ Proximity	Display only the readings from detectors or sensors within the number of hours you specified in the previous step, and eliminate readings that are redundant because they were taken at the same location.

   Detector-only filters

   Some filters are designed to work specifically for detector information.

   Latest reading, regardless of detector status

   • To the right of the list, click the icon to the left of Show Filter, and then choose Latest Reading.

     

     The list reduces to display only the most-recent reading for each detectors.

   Latest reading from detectors in alarm status

   • To the right of the list, click the icon to the left of Show Filter, and then choose Latest Reading with Alarm Cycle.

     

     The list reduces to display only the readings from detectors currently in an active alarm status. If you have multiple alarms, the information will cycle through the alarms.

   Sensor-only filter

   You can filter for a specific type of sensor, based on the types found in your database.

   • To the right of the list, click Filter Sensor Type, then choose the name of the substance being sensed from the menu of sensor types that appears.

     

     The list reduces to display only the sensors for that type of substance.

     Tip: To display all types of sensors in the list again, choose Filter Sensor Type → No Filter.
