Overview
The IEI eMerge MicroNode unit supports 2 readers, 4 supervised inputs, 4 outputs, one temperature
input, and a 12VDC power out connector. Two of the outputs can be configured as “wet” or powered
outputs to power 24VDC strikes. In addition, 12VDC strikes and maglocks can be powered using the
12VDC out connectors and an output relay.
24VDC maglocks cannot be powered by the MicroNode, however, if they are powered by an external
24VDC source the MicroNode output relays can control them. Door strikes and maglocks that are
tested with the MicroNode are listed in the appendix.
The MicroNode can also power two readers , and oth er 12V devic es such as a PIR Reques t to Exit
input or an alarm sounder.
The MicroNode is PoE (Power over Ethernet) capable or can be powered by 12VDC ±5% at 2 Amps.
The on-board relays are rated at 3 Amps maximum and can control up to 24V AC or DC.
To install the IEI eMerge MicroNode follow the procedures below.
Connecting power and the network to the MicroNode
CAUTION: Do not supply power to the boards until all connections are made and the
mounting plate is remounted in the wall mounted box. If you are using PoE make sure that
the far end of the network cable is not connected when you plug in to the network connector.
1. You can remove the mounting plate assembly with the boards attached from the mounting
box to make wiring connections easier. See the image below.

Using Power over Ethernet (PoE)
2. Connect the CAT 5 network cable to the RJ-45 network connector on the underside of the
Bottom Board. See the image below. When using Power over Ethernet no further
connections on the Bottom Board will be necessary.
NOTE: The MicroNode requires PoE to conform to the IEEE 802.3af standard. This provides
nominal 48 VDC at a maximum of 400mA.
With PoE as the power source the total power available for all external 12V output is 500 mA
(6 watts).
or
Using a 12 VDC power supply
1. Wire the power in connector on the topside of the Bottom Board with a 12VDC power source
at no less than 2 Amps. See the image below.
NOTE: With an external 12VDC power supply as the power source the total power available
for all external 12V output is 1100 mA (13.2 watts).
2. Connect the CAT 5 network cable to the RJ-45 network connector on the bottom of the
Bottom Board. See the image below.

Connecting and powering door hardware with the MicroNode
The MicroNode can supply power to up to two strikes or maglocks, two readers, and two other
door input devices such as a PIR Request to Exit.
Wiring and powering 24VDC door strikes:
NOTE: 24VDC maglocks cannot be directly powered by the MicroNode.
1. Wire the door strikes to output connectors 1 or 3.
NOTE: Only outputs 1 and 3 can be used for powering 24V strikes. The example in the image
below uses output 1 and the strike switch for output 1.
2. Set the Strike switch for that output to the “STRIKE” position as shown for output 1 in the Top
Board image below. This allows the capacitor near the switch to provide power to flip the
strike.
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).

NOTE: With PoE as the power source the total power available for all external devices is 500

With an external 12VDC 2amp power supply as the power source the total steady-state
power available for all external output is 12VDC at 1100 mA (13.2 watts).

Wiring and powering 12VDC door strikes and maglocks:
NOTE: 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. The example in the image
below uses output 1 and the strike switch for output 1.
1. If using outputs 1 or 3 set the strike switch for that output to the “NORM” position as shown
for output 1 in the top board image below.
2. Connect a wire (minimum 20 AWG) from the positive (+) side of the 12VDC power out
connector to the common pin of the chosen output connector.
3. Connect a wire from the normally open (NO) pin of the output to one side of the strike or
maglock.
4. Connect a wire from the other side of the strike or maglock to the ground (gnd) pin of the
12VDC power out connector.

NOTE: With PoE as the power source the total power available for all external 12V output is
500 mA (6 watts).
With an external 12VDC 2amp power supply as the power source the total power available for all
external 12V output is 1100 mA (13.2 watts).

Wiring other outputs not requiring power from the MicroNode:
NOTE: Any output can be used. If output 2 or 4 is selected simply wire the output state wires
to the output connector. The example in the image below uses output 4.
See the CAUTION further below regarding outputs 1 and 3.
1. Connect one wire from the output to the common pin of the output connector.
2. Connect the other wire from the output to either the normally open (NO) or normally closed
(NC) pin of the output connector.
CAUTION: If output 1 or 3 is selected you must set the strike switch in the NORM
position. Otherwise power will be delivered to this output device. See the image below.
3. Ensure that the strike switch is in the NORM position. See the drawing below showing output
1 and its strike switch.
4. Connect one wire from the output to the common pin of the output connector.
5. Connect the other wire from the output to either the normally open (NO) or normally closed
(NC) pin of the output connector.

Wiring and powering inputs:
1. If you are powering other door devices such as a PIR Request to Exit, wire that device to one
pair of 12V and ground connectors on the power out connector as shown in the image below.
NOTE: There are connectors for two devices but more may be supported as long as the total
current consumption for readers and devices does not exceed:
1100 mA when power is supplied by a 12VDC 2A external supply (13.2 watts);
500 mA when power is supplied by PoE (6 watts).
Power out and Input connectors on the Top board.
2. Connect the input state wires to a two-pin input connector.
NOTE: These inputs can support a wide variety of input supervision types. To configure
inputs and input supervision types select Setup : Alarms : Inputs from the security
application menu.

for all external 12V output is 1100 mA (13.2 watts).
Wiring IEI temperature sensors:
1. Wire the IEI temperature sensor as shown in the diagram below. The black wire from the IEI
sensor is the ground.

Re-assemble and apply power:
1. Replace the mounting plate assembly with the boards attached into the mounting box.
2. Supply power to the MicroNode unit by powering the external 12VDC power supply or
connecting the far end of the network cable to a PoE switch or mid-span power injector.
