Description
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.
Packing list:
• 1 x Room Controller NIRC4
• 1 x Cover rear
• 1 x Cover front
• 1 x Cover dome
• 1 x Ferrite core round cable snap

INSTALLATION GUIDE
Room Controller 4 (NIRC4-xMN) Installation
3 Installation
The NIRC4-xMN has an IP40 ingress protection. The areas in which NIRC4-xMNs are to be installed must be
clean, dry, and weatherproof. The walls on which devices are to be installed should be finished (painted,
wall papered, etc.) before the devices are installed. It is important to have the appropriate length of free
cable available at every location where the NIRC4-xMN is to be installed. The length of stripped cable and
the length of exposed copper wire shall conform to the installation instructions for each module that is to be
connected.

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.

To remove the knockouts
1. Locate the knockouts to be removed from the bottom or right side of the base. See Figure 1. NIRC4-
xMN base orientation and cutouts, page 5, items 3.
2. Using a cutter or pliers, carefully remove the excess plastic from the knockouts.

Mounting
INSTALLATION GUIDE
Room Controller 4 (NIRC4-xMN)
To mount the NIRC4-x N base on a wall
1. Place the base against a flat wall and orient it so that arrow is pointing up and that the base is level.
(See Figure 1. NIRC4-xMN base orientation and cutouts, page 5, item 1.) Use a leveling device to check,
if necessary.
2. Make sure that the knockouts are pointing down and to the right. (See Figure 1. NIRC4-xMN base
orientation and cutouts, page 5, items 3).
3. Using the base as a template, mark four holes for the screws using the slotted fitting holes located in
the base.
4. Remove the base and drill holes for the screws that will be used, such as wood, concrete, or drywall
screws, or screws with anchors.
5. Place the base (with the knockouts removed) over the holes, insert the screws, and then tighten.
6. Pull the cables through the knockout holes and follow the directions in the following sections.
The NIRC4-xMN must be mounted in a way that the module is firmly attached to the background.
