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.
