Check-in
button
Pressing and releasing the check-in button during normal operation initiates a check-in to OneVue. During a check-in, all logged
readings are transmitted to OneVue and any pending updates are downloaded to the device. During an active check-in connection,
additional pressing of the check-in button is ignored.
When the check-in button is pressed and released, the device emits a series of audio beeps indicating its connection sequence. When a
device emits beeps as indicated below and displays Signal Ok, this indicates a successful check-in.
• 1 beep: device booted
• 2 beeps: device connected to network
• 3 beeps: device connected to OneVue
If a check-in fails, commonly due to the device cannot establish a network connection, all logged readings are stored in the device's non-
volatile memory. If the number of failed check-ins exceeds the size of the non-volatile memory, the oldest readings are overwritten.
Primex sensor devices store up to 4096 readings.
Sensor LED indicators
Primex sensors have three LED indicators that provide a visual indicator of its current state.
When power is first applied, the LCD segments display and LED indicators briefly illuminate.

All power methods: LED illuminated and flashing
Sensor audio alert
Primex sensors are equipped with an audio alert that is activated during a reading Alarm state (Out of Range, Past
Alarm Delay status). The audio alert is activated when a reading is out of range and the time period it has been out of
range has exceeded the time period set in its Alarm Delay.
• When the audio alert is enabled and the sensor is in a reading alarm state, the device emits an audio beep at one
second intervals. Also, when powered by AC or PoE, the sensor's red LED flashes once per second.
• During a reading Alarm state, pressing and immediately releasing the silence button clears the audio alert and
stops the red LED from flashing, but does not acknowledge the alert in your OneVue account. The audio alert
resumes once the time period of the Resume Audio Alert setting has been reached. Audio alert settings are
configured from a sensor's gateway profile.
