MicroNode
eMerge MicroNode Compact Expansion Node with Embedded ACM
Overview
The eMerge MicroNode brings new levels of convenience
and capability to access control systems; two card readers,
four inputs, four outputs, and one temperature point - all
housed in a 7-inch square package. Beyond its convenient
size is the fact that the MicroNode can be powered by a
standard 12 VDC power supply or Power-over-Ethernet
(PoE) which powers all components including electric
locking devices.†
As a native IP-based network appliance, the eMerge
communicates over familiar LANs or WANs after obtaining
an IP address by DHCP or static configuration. Like all
eMerge components, the MicroNode secures its own
communications, making it safe for deployment over public
networks, including the Internet. As with the larger eMerge
Expansion Node (EXN), the MicroNode is automatically
discovered and supports visual configuration in any Web
browser through the eMerge Network Controller (NC).
Connection over an IP network using PoE is advantageous
because it provides a single cable connection with a central
point for battery backup. When using this method, all access
control functions - including electric locks - continue to
operate during power outages without the need for multiple
independent battery backup units.
Because the MicroNode is remote from the card readers
and other components, it can be placed safely on the
secure side of a barrier (typically in a wall or drop-ceiling)
so that compromising an externally mounted card reader
does not expose the data network. In fact, the MicroNode is
typically a direct replacement for legacy two-reader access
control devices, making it the ideal retrofit device for older
technology access control systems without replacement of
readers, inputs, or lock outputs. MicroNode even provides a
12 VDC output for powering PIRs and similar REX devices.
The MicroNode is supplied in a 7-inch square mounting box
with tamper switch, status indicator light, and keyed lock.
The board set is mounted to a removable back plate to
facilitate wiring in confined spaces.
