Sensor power input
The power source of a Primex sensor is dependent upon the model's power specifications, 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 Disulfide 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.
• Use of alkaline batteries is not recommended.

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 configured from the sensor's gateway profile.
