INSTALLATION GUIDE
Room Controller 4 (NIRC4-xMN)
2 Description
The Room Controller (NIRC4) is a teleCARE IP controller establishing a decentralized node on the IP
network. A teleCARE IP Room Controller acts as a gateway between the four digital room buses and the IP
network. The NIRC4 is compatible with the NU-series modules, allowing 12 NU-series modules per room
bus.
It has a connection for an optional wireless transceiver (NIRX) that supports wireless nurse calls and a
connection for an optional voice module (NIVP4) that supports speech for NU-series modules. The NIRC4
can also serve as a corridor lamp supporting up to four LED boards behind a translucent dome cover. The
LED boards supported are the NILD2 and the dedicated workflow LED board (NILD4–RGB). The NIRC4 has
an integrated USB 2.0HS Host Port and Device Port with integrated support for the connection of the
Wireless Gateway.
The NIRC4 connects to the IP network using a 100Mb Ethernet connection. The input power can be
provided through the LAN port using power over ethernet (PoE), or through an auxiliary power supply via a
PoE Midspan. The NIRC4 includes firmware upgrade support for connected NU-series modules.

Mounting
INSTALLATION GUIDE
Room Controller 4 (NIRC4-xMN)
4 ounting
The base of the NIRC4-xMN mounts to backboxes using an array of holes that allow for mounting on
various EU and North American-style backboxes. In areas where no backboxes are available, the base can
be mounted directly onto flat wall surfaces.
Caution: To prevent a fire hazard because of dust buildup inside the NIRC4-xMN, regular
inspection and/or cleaning of the NIRC4-xMN is required.
Take proper measures to avoid spreading dust and other particles when applying
maintenance to an NIRC4-xMN that is mounted inside a clinical area.
4.1 ount the NIRC4-x N base onto a backbox
1. Place the base over the backbox with the spring type holding clip (1) pointing to the left.
2. For EU-style backboxes, loosen the screws so that approximately 5mm extend from the backbox so
that the heads of the screws can pass through the key-hole slots.
For North American-style backboxes, insert the screws (included) through the backplate and into the 2-
gang backbox.
3. Position the base until its top is level.
4. Tighten the screws until they are snug. Do not overtighten.
5. Pull the cables from the backbox through the base hole.

Room Controller 4 (NIRC4-xMN) Mounting
4.2 ount the Base without a Backbox
When mounting the NIRC4-xMN on a drywall without a backbox, mount the base of the NIRC4-xMN directly
to a flat wall surface using four screws suitable for the wall type.
Cable wires should enter and leave the device’s housing through the hole in the center of the base, or
through the knockouts at the bottom or right side of the base. Depending on the number of wires entering
the base, you may need to remove a portion of the cable’s jacket to ensure it will fit through the knockout.
When choosing a wall location for an NIRC4-xMN, consider where the connecting cables are located. If the
connecting cables run inside the wall, locate the base of the NIRC4-xMN over the hole where the cables
exit from the wall. If the connecting cables are run in a channel outside the wall, locate the base above or to
the left of the channel, where the cables exit the channel. The cables should enter through the knockout
holes in the base of the NIRC4-xMN.
Do not distort or twist the base when mounting it to a wall. If the base is distorted, the NIRC4-xMN
dome cover will not fit properly and may fall off.
