The Room Controller 4 (NIRC4-xMN) Installation Guide contains important instructions when installing and maintaining the NIRC4-xMN. To ensure a safe working environment during the installation and operation of the NIRC4-xMN, the following safety symbols appear throughout this document to indicate dangerous conditions and important safety instructions. -
Page 4: Description
INSTALLATION GUIDE Description Room Controller 4 (NIRC4-xMN) 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. -
Page 5: Installation
Installation 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. -
Page 6: Mounting
Room Controller 4 (NIRC4-xMN) Mounting 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. -
Page 7: Mount The Base Without A Backbox
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. - Page 8 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. TD 93351EN / 21 March 2022 / Ver. B...

Page 11: Setting The Room Bus Type Selection
Before connecting any of the wires, first set the bus-type selection DIP switch to match the modules (NU- series or NI-series) that are going to be connected to the NIRC4-xMN. The following figure illustrates the DIP switch found on the back of a NIRC4-xMN circuit board. Figure 4. Room bus type selection DIP switch... -
Page 12: Enabling Auxiliary Power Supply
When using external power via a power injector (PoE Midspan), make sure that the jumper is present on the board. See item 5 of Figure 3. NIRC4-xMN circuit board - back, page The jumper is only available on the NIRC4 with circuit board revision D or later. -
Page 13: Preparing The Room Bus Cables
Strip the outer jacket of the cables to a length of 150mm or 6 inch, then position the cable in the backbox so that only the stripped wires enter the room controller housing. Figure 5. Stripping and positioning the cables for the NIRC4-xMN TD 93351EN / 21 March 2022 / Ver. B... -
Page 14: Terminating And Mounting Room Bus Connectors For Nu-Series Modules
Terminating and Mounting Room Bus Connectors for NU-series Modules The NIRC4-xMN includes four active room bus terminals. For the NU-series modules, ensure that each room bus cable is identified and properly terminated with an 8-pin block connector (NICT-8AA). The following figure shows the correct pinout for terminating the active room bus cables. -
