Parameters of sensors with a discrete output of the VUTLAN device can be located depending on their physical location in the sub-branches:
ctlInternalSensors - main system sensors;
ctlInternalSensorsDiscretsTable;
ctlCANSensors - CAN bus sensors;
ctlCANSensorsDiscretsTable;
ctlRsSensors - serial port sensors;
ctlRsSensorsDiscretsTable;
Example. Viewing discrete sensors:

102001 2002 1 "door" "Analog-1" "normal" 1 60 50 0 "" |
The location of the sensor in the system is determined by the module identifier Module in which this sensor is physically located and with the port number in the unit - Num.
Sensor with a discrete output maybe may only in states:
'normal'
'alarm'
'not connected'
If necessary, the inversion is performed by setting the state '1' in a field Reverse (default '0').

Reset smoke detectors
For smoke detectors on the CAN bus (VT460 sensor), a reset of the alarm state via the SNMP SET command is available. To do this, write the string value "reset smoke" (without the quotes) by the OID .1.3.6.1.4.1.39052.6.1.1.11 (ctlCANSensorsDiscretSpecific) with the sensor ID.
Other smoke sensors are reset by the SNMP SET command by controlling the state of the "Analog Power" switch, you must turn it off for 15 seconds and then turn the power back on. Read more about the relay here.
