IEI eMerge™ MicroNode
Extreme QuickStart
Connecting Power
For Power over Ethernet (PoE)
The MicroNode requires PoE to conform to the IEEE 802.3af standard. This provides nominal
48 VDC at a maximum of 400mA. With PoE, no external power supply is needed.
For an External Power Supply
The MicroNode requires 12 VDC 2 Amp power supply. With external power supply, no PoE is
needed. The power supply must be located no further than 50 feet from the MicroNode.

Wiring and powering 12VDC door strikes and maglocks
Any output can be used for powering 12V strikes or maglocks. If output 1 or 3 is selected you
must set the strike switch in the NORM position. Wires must be a minimum of 20 AWG.

Wiring and powering 24VDC door strikes
Only outputs 1 and 3 can be used for powering 24V strikes. 24V maglocks cannot be powered
by the MicroNode. The example in the image below uses output 1 and the strike switch for
output 1. Wires must be a minimum of 20 AWG.
CAUTION: Polarity shown must be observed if using a diode to clamp the kickback voltage from
the strikes. IEI recommends the use of a diode, varistor, or transient voltage suppressor (TVS).

Wiring temperature sensors
NOTE: IEI temperature sensors can be located up to 500 feet from the MicroNode using CAT5
twisted pair cable. The black wire from the sensor is the ground.
