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 rst applied, the LCD segments display and LED indicators briey illuminate.

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 ashes 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 ashing, 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
congured from a sensor's gateway prole.

Sensor power input
The power source of a Primex sensor is dependent upon the model's power specications, including AC power with
battery backup, battery-powered, and Power over Ethernet (PoE). All models are compatible with the AC power adapter
accessory.
Models using AC power or PoE can also use battery power as a backup power source in the event of a power loss.
During battery backup, the device operates on battery power and continues to log and transmit readings until the
primary power source is restored.
All data stored in non-volatile memory is lost when a device loses all power.
Battery-power • 3.0v Primex Lithium/Iron Disulde Battery Pack or two AA 1.5V Energizer® Ultimate Lithium batteries.
• Temperature, Temperature and Humidity, and Differential Pressure Sensors
When operating solely on battery power, estimated battery life is up to 18 months with use of Lithium 1.5V batteries;
estimation based on 1 hour Logging Interval, 8 hour Check-In Interval, and adequate wireless signal.
• Water Leak and Contact Closure Sensors (backup battery power use only)
When operating solely on battery backup power, estimated battery life is 7 days. This estimation is based on the use of
Lithium 1.5V batteries, 1 hour Logging Interval, 8 hour Check-In Interval, and adequate wireless signal.

Manually initiate a sensor to check-in to OneVue
While locally at a sensor device, you can initiate a manual check-in. During each check-in all logged reading(s) are
transmitted to OneVue and any pending updates are downloaded to the sensor.
A Primex sensor checks-in to your OneVue account at regular intervals, per the frequency set in its Check-In Interval
setting. The Logging Interval and Check-In Interval settings are congured from the sensor's gateway prole.

2. 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.
•If you only hear 1 beep: The device could not connect to the facility's network. Contact the onsite IT department
to seek assistance to determine why the device failed to connect to the network. It's recommended to verify the
network assigned to the sensor's gateway (select the Monitored Asset > select the sensor type > select its
Gateway ID link > verify its assigned Network.
•If you hear 1 beep followed by 2 beeps: The device could not connect to OneVue. Log in to OneVue and verify its
last check-in. If in an Alarm state with an Unresponsive status, contact your Primex support team.
About Differential Pressure Sensor door switch monitoring
The OneVue Differential Pressure Sensor is equipped with an optional door switch monitoring feature. This feature is
designed to monitor whether a door in the room being monitored is open or closed - when a door is intentionally left
open for an extended period of time signaling that the room is not in use. When a door status change is detected, the
sensor device automatically transmits the door status to OneVue.
To enable the door monitoring feature, the sensor's device door jumper must be enabled (jumper removed) and a
magnetic door switch is required to be wired to the sensor door terminal block. By factory default, the door monitoring
feature is disabled. For door switch monitoring, it's recommended to supply AC power to the sensor device and apply
battery power for backup power purposes only.
Use door switch monitoring to manage when monitoring is enabled or disabled
The Differential Pressure Sensor door monitoring feature is designed to allow the status of a magnetic door switch and
the sensor's Door Delay setting time period to manage when a monitored asset is set to the Alarms Disabled state.
When set to the Alarms Disabled state, OneVue does not monitor the differential pressure readings or the sensor device
operating status and will not generate alerts for the Monitored Asset.
Use of this feature eliminates manually setting the Monitored Asset to a Suspended state when a room is not in use
and is not required to be monitored. When a room is not in use, you can simply open the door to disable the monitoring
of the room's differential pressure.
How it works - door monitoring
1. When an Open status is detected, the sensor device automatically transmits an Open status to OneVue and the
sensor status is set to Open.
