5 Control Equipment
This section describes the installation instructions for the following products:
• “Room Controller” (details on page 19)
• “Blank Front Cover for the Room Controller” (details on page 22)
• “Corridor Lamp (NICL)” (details on page 49)
• “System Manager (NISM2)” (details on page 57)
5.1 Preparation
It is important to refer to the following teleCARE IP control module installation instructions for
complete electrical connection and assembly details before starting the installation.
The Ingress Protection of the control modules is IP40, therefore the areas in which the teleCARE
equipment is to be installed must be clean, dry and weatherproof.
The walls on which the control modules are to be installed should be finished (painted, wall papered
etc.) before the control module is installed.
It is important to have the appropriate length of free cable pulled out at every location where the
control module is to be installed. The length of stripped cable and length of exposed copper wire must
conform to the relevant installation instructions. Electrical power to the equipment must be off before
connecting any devices.
5.2 Room Controller
5.2.1 NIRC
Note: Except when specifically mentioned otherwise, the references to “room controller”
used in this document are applicable to both the NIRC and NIRC3.
The Room Controller (NIRC) has been tested and found to comply with the emission levels for a Class
B device as described in EN55022:2010.
The input power for the NIRC shall be supplied over an external 24Vdc power supply bus,. The
external power supply input requirement is 24Vdc ± 10%. The power input has an on-board, self-
resetting fuse.
Each room bus has four wires, consisting of: data, voice, power (5.5Vdc) and ground (0V). The room
bus power output is used for the power supply to the connected peripheral device. Each room bus
power output has a self-resetting 650mA fuse.
The NIRC has a 6-pole output connector for an external corridor lamp with 4 LEDs. These outputs are
in parallel to the NIRC’s on-board LED connectors. Additionally, the NIRC has an internal buzzer for
optional audible signaling of calls and faults.
The NIRC can support up to 3 slave corridor lamps, however, the NIRC is capable of providing the
power supply for no more than 2 slave corridor lamps. Each room bus can accept one corridor lamp
and each corridor lamp has the fixed room bus address 5.
The NIRC can accommodate 4 LED Lamp Boards (NILDs), enabling the NIRC to be used as a corridor
lamp. The NIRC also has the provisions to provide 24Vdc power for up to two teleCARE IP Corridor
Lamps (NICLs).
When an NICL data bus is connected to one of the three NIRC room buses, it becomes an active
corridor lamp that operates independently of the NIRC. In this configuration, the NICL takes up fixed
