Sensor power input

  • Updated

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. During battery backup, the device operates on its battery power and continues to log and transmit readings until the primary power source is restored.

AC power

  • AC power adapter: 5V DC USB Mini B (5 pin) connector interface, 5 ft (1.5 m) cable

  • Input: U.S./Canada: 120V~, 60Hz, 0.4A | Outside U.S.: 100 to 240V~, 50/60Hz, 0.4A

  • Output: 5V DC

  • Max current: 1A

  • Optional power extension cable: USB power cable 6.5 ft. (2 m), Mini B (5 pin) M and Mini B (5 pin) F connector

Power over Ethernet (PoE)

Temperature, Temperature and Humidity, Differential Pressure, Water Leak, and Contact Closure Sensors

  • Compliant with IEEE 802.3af standard and compatible with 802.3at standard

Battery power

Recommend for backup power use only

  • 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.
