"unavailable" State
The
unavailable
state means the connectivity or communications with the
sensor is lost.
The EMX pings all managed sensors at regular intervals in seconds. If it
does not detect a particular sensor for three consecutive scans, the
unavailable
state is displayed for that sensor.
When the communication with a contact closure sensor's processor is
lost, all detectors (that is, all switches) connected to the same sensor
package show the "unavailable" state.
Note: When the sensor is deemed unavailable, the existing sensor
configuration remains unchanged. For example, the ID number assigned
to the sensor remains associated with it.
The EMX continues to ping unavailable sensors, and moves out of the
unavailable
state after detecting the sensor for two consecutive scans.
For DPX2, DPX3 or DX sensor packages, all of the connected sensor
packages also enter the
unavailable
states if any of them is upgrading its
sensor firmware.
