Sensor power input
The power source of a Primex sensor is dependent upon the model's power specications, 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.

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.
Page 10

2. When the door switch has remained in an Open status for longer than the sensor's Door Delay setting, the sensor
and its assigned Monitored Asset (room) is automatically set to an Alarms Disabled state with a status of Past
Door Delay.
3. During the Alarms Disabled state, the sensor device continues to transmit its readings and operating statuses, but
the data is only logged and stored in your OneVue account. OneVue does not monitor the sensor readings or
device operating status and disables the alerts assigned to the Monitored Asset during the Alarms Disabled state.
4. When the door switch changes from an Open status to a Closed status, the device automatically transmits the
Closed status to OneVue. The sensor and its Monitored Asset (room) are then set to a Normal state and the
system begins to monitor the sensor readings and device operating conditions.

Mounting guidelines
When mounting and installing a Differential Pressure Sensor it's recommend to consider the following guidelines.
Sensor mounting location guidelines
• Sensor is commonly mounted in the Reference Space.
• Sensor mounting location is required to in close proximity to wall plate to allow tubing to be connected to the sensor
pressure port.
• Sensor must be mounted vertically; pressure ports pointing down. If the pressure ports point upward, condensation
can collect inside the sensor causing damage to the device.
• Easily accessible for maintenance and clear from obstructions. Avoid a location that would interfere with the use of
the monitored unit or area.
• Wireless Network use
It's recommended that the device is in a clear line of sight to a wireless access point. If the location is NOT in a clear
line of sight to a wireless access point, its LCD screen must be above the unit it's being mounted to.
Wireless signal strength of -60db or better at the mounting location. It's recommended to measure the strength with
a Wi-Fi analyzer app on a mobile phone.
• PoE/Ethernet use
An open, active network port in close proximity to the mounting location.
• AC power
Outlet within 5 ft. (1.5 m) from its mounting location. Devices using AC or PoE power 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.
CAUTION
The device is shock and vibration resistant; however, be careful not to drop or install the device in a
location where it could be exposed to excessive vibration.
Page 13

Tubing guidelines
• It's recommended to only use the supplied exible silicone tubes.
• Tubing is free of crimps or obstructions that may inhibit airow to the pressure ports.
• Tubing is clean and do not allow material to fall into the pressure ports, as contamination could damage the sensors.
• Arrange tubing to minimize stress on the connections to the pressure ports.
• Tubing can be cut to length to support application use.
• If the tubing used is longer than the supplied 6 ft. (1.82 m) tubing, reading accuracy may be affected due to reduced
air ow within the tubing. A general rule is that for each additional 2 ft. (.61 m) of tubing, a 1% of error is introduced
into the differential pressure reading. For applications that are only interested in a positive or negative pressure
indication, the overall accuracy of the reading may not be an issue. For application use requiring tubing lengths that
exceed 6 ft. (1.82 m), please contact your Primex support representative to calculate the extended tubing error rate.
Step 1: Verify sensor conguration
Prior to installation, a sensor device must be congured for use with OneVue. A sensor is either congured prior to
shipment through Device Preconguration or onsite using the OWDC app.
•Device  completed: white label with congured settings is afxed to the backside of the sensor.
Sensor has been congured with network settings allowing its connection to OneVue and also added to OneVue.
Proceed to next install step.
•OWDC onsite  required: Sensor shipped with factory default settings and is not added to OneVue.
You must congure the sensor now using the OWDC app.
Step 2: Insert sensor batteries and turn on battery power
1. Remove device cover; simultaneously press the two tabs located on the top side of the device (A).
2. Insert the 3.0v Primex Lithium/Iron Disulde Battery Pack or two 1.5v Lithium AA batteries. Follow the symbols
showing the correct way to position the positive (+) and negative (-) ends of the battery pack.
3. Located to the lower-right of the battery compartment, set the battery on/off switch to the Up (On) position (B).
4. Replace the device cover.

Page 14

Step 3: Route tubing between Controlled and Reference Space
1. Drill a hole through each side of the wall that is large enough to pass through the tubing. Wall cut out should not
exceed the dimension of the supplied wall plate.
2. From the Reference Space, rst route tubing through rubber sealed grommet, then through wall plate, and through
the wall to the Controlled Space wall plate.
3. From the Controlled Space (monitored room), connect the pickup screen to the tubing routed from the Reference
Space.
4. Attach Controlled Space wall plate to the tubing by screwing the screen pickup into the mating connector. Make
sure to use the backing gasket on the wall plate to ensure no pressure leaks.
5. Secure Controlled Space wall plate to surface.
Step 4: Mount sensor, connect tubing, and apply power
1. Mount sensor using the key-hole slot on backside of unit.
Determine the mounting location by referencing the key-hole slot located on the back of the device. Pre-drill
mounting hole into the wall surface and insert wall anchor.
Insert a #6 drywall screw into the wall anchor, leaving approximately 3/8 in. (0.95 cm) of the screw head exposed
for hanging.
Attach device by sliding the key-hole slot onto the mounting screw. Ensure the device is properly secured and level.
Optionally mount to surface using the supplied 3M™ Dual Lock Fastener & Tape, 2" x 1" strips. It's
recommended to place the strip(s) horizontally.
2. Attach tubing to appropriate port located on the bottom side of the sensor. Tubing can be cut to length as required.
Where the sensor is mounted determines the port the tubing is attached to. Sensor can monitor for either for
Positive or Negative pressure in the Controlled space, which is congured from OneVue.
Sensor located in Reference space: Push tubing onto the sensor H (High) port.
Sensor located in Controlled space: Push tubing onto the sensor L (Low) port.
3. Dress and secure the tubing as needed. Arrange the tubing to minimize stress on the connections and ensure there
are no kinks in the tubing.
4. Apply primary power to sensor; AC or PoE.
5. Secure Reference Space wall plate to surface.
6. Snap the sensor's removable port cover into place.
Step 5: Verify connection to OneVue
1. Verify Signal OK is displayed on the LCD screen, which indicates it successfully checked-in. When power was
applied, the sensor initiated a check-in to OneVue.
Page 15

2. If Signal OK is not displayed, initiate a manual check-in. From the front of the sensor, press and release the check-in
button . It emits a series of audio beeps indicating its connection sequence. During an active check-in
connection, additional pressing of the check-in button is ignored.
• 1 beep: device booted
• 2 beeps: device connected to network
• 3 beeps: device connected to OneVue
Step 6: Verify OneVue settings
Verify the following settings are congured to meet the requirements of the condition being monitored.
1. Monitored Asset settings (Go to Monitoring > Monitored Assets)
Each Primex sensor device is assigned to a Monitored Asset and its readings or monitored conditions generate the
Monitored Asset's current and historical readings. In addition, sensor operating condition data is linked to its
assigned Monitored Asset. When a sensor enters a Warning or Alarm state, its assigned Monitored Asset is also
set to an Alarm or Warning state.
• Sensor assigned to a Monitored Asset. Go to Devices > Sensors > select sensor > verify assigned Monitored
Asset.
• Monitored Asset assigned to sensor is added to an Alert Rule.
• Monitored Asset assigned to sensor is added to a Report Prole.
• Users responsible for the monitored condition are assigned to Monitored Asset's Business Unit.
Page 16

2. Sensor settings (Go go Monitoring > Monitored Assets > select Monitored Asset > select sensor.
•Normal Condition
The Normal Condition is the expected, operating range or condition of the Monitored Asset assigned to the
sensor. The settings vary based on the type of sensor and the condition being monitored.
•Alarm Delay
Alarm Delay sets the amount of time OneVue delays setting the sensor and its assigned Monitored Asset to an
Alarm state. When a sensor reading is not within its Normal Condition (an Out of Range status) and it remains
Out of Range for the time period set in its Alarm Delay setting, the sensor and Monitored Asset are then set to an
Alarm state with a status of Out of Range, Past Alarm Delay.
•Audio Alert (sensor gateway setting)
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.
•Logging Interval (sensor gateway setting)
The Logging Interval is how frequent a sensor logs a reading and stores it into its internal memory. All logged
readings are then sent to OneVue at the frequency set the sensor's Check-in Interval frequency.
•Check-in Interval (sensor gateway setting)
The Check-in Interval is the frequency a sensor connects to the facility's network to sends its logged readings to
OneVue. Also, during each check-in, pending setting updates are downloaded to the sensor.
•Unresponsive Timeout (sensor gateway setting)
The Unresponsive Timeout is the maximum amount of time a Primex device can go without a check-in to
OneVue. When this time limit is exceeded, the device is set to an Alarm state with an Unresponsive status.
Page 17

Differential Pressure Install: Enable 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 status change is
detected, the sensor device automatically transmits the door status to OneVue.
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.
Enable door switch monitoring
To enable the door monitoring feature, the device door jumper must be enabled (jumper removed) and a door switch is
required to be wired to the device door terminal block. By factory default, the door monitoring feature is disabled.
IMPORTANT
For door switch monitoring, it's recommended to supply AC power to the sensor device and apply
battery power for backup power purposes only.
1. Remove the device cover; simultaneously press the two tabs located on the top side of the device.
2. Remove the bottom plate containing the dual port sensor by applying slight outward pressure on the sides of the
sensor housing to allow the bottom plate to slide out. It's recommended to disconnect the cable connection to the
dual port sensor and note the cable orientation and pin connection.
3. Remove the 2-pin terminal block located on the edge of the lower circuit board. The use of needle nose pliers can
be used to pull off the terminal block header.
4. Remove the jumper from the lower circuit board. Move the jumper to one pin only on jumper block to retain the
jumper.

5. Wire the two door switch wires to the 2-pin terminal block header by loosening the lock down screws on the
header. Insert the wires and tighten the screws to secure the wires.
6. Reinsert the terminal block header to the receptacle on the lower circuit board
7. Reinstall the bottom plate containing the dual port sensor by routing the door switch wires trough the wire slot on
the bottom plate cover – make sure to reattach connecting cable to dual port sensor if previously removed.
Applying slight outward pressure on the sides of the sensor housing allows bottom plate to slide in. Make sure the
bottom plate slides into the retention tab slots on the housing.
8. Reattach the device cover.
The sensor is now congured to monitor the door status set by the magnetic door switch.
9. Log into OneVue and set the sensor's Door Delay. Go to Devices > Sensors > select sensor > select Show Advanced
Options > set Door Delay (minutes).
