The Room Controller (NIRC3) 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 NIRC3 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.
The NIRC3 has four room buses. Each room bus has four wires, consisting of: data, voice, power (5.5V
DC) and ground (0V). Each room bus power output has a self-resetting 650mA fuse. The room bus power
output provides power to the connected peripheral devices. The NIRC3 can support up to four slave
corridor lamps NICL2. Each room bus can accept one corridor lamp and each corridor lamp has the fixed
room bus address 5.
The NIRC3 can accommodate 4 LED Lamp Boards (NILD2s), enabling the NIRC3 to be used as a corridor
lamp. The NIRC3 also has the provisions to provide 24Vdc power for up to two teleCARE IP Corridor
Lamps (NICL2s).
When an NICL2 data bus is connected to one of the four room buses, it becomes an active corridor lamp
that operates independently of the NIRC3. In this configuration, the NICL2 takes up fixed Room Bus
Address 5 on the NIRC3 bus. When connected to the NIRC3 External Corridor Lamp Outputs bus, an
NICL2 becomes a passive corridor lamp and the LEDs operate in parallel with the NIRC3 display lamps.
The NIRC3 can be extended with an optional voice piggyback module (NIVP) to include speech and with
an optional transceiver module (NIRX) for wireless call functionality.
5.2.1 Room Bus Addresses
Each room bus of the NIRC3 support eight addresses. The lowest four addresses (0 - 3) are for teleCARE
IP peripherals and the highest four address (4 - 7) are dedicated for devices, such as the duty selector,
card reader and the corridor lamp.
The total room bus address applications are summarized in the following table:
