Installation Guide teleCARE IP TD 93021US Rev A 5.5.1 Connecting the 24Vdc Power Supply The 24Vdc power supply uses a 2-pole connection terminal as described in section 5.4.2 on page 33. The connection point on the room controller circuit board for the power supply is shown in section 5.3.2 on page 28. The power supply wires should be guided around the sides of the room controller housing and held in place by the wire holding clip, as shown in the following illustration: Figure 36.
Installation Guide teleCARE IP TD 93021US Rev A Use the Wire Holding Clip NIRC3 Figure 37. NIRC3 - Connecting the 24V DC power supply Note: An external power connection is not required when Power over Ethernet - PoE is used to power the NIRC3. 5.5.2 Connecting the Power Supply and Corridor Lamp Power Outputs The room controller supports two corridor lamps and each has a 2-pole connector similar to the 24Vdc power supply, as described in section 5.4.2 on page 33.
Installation Guide teleCARE IP TD 93021US Rev A Use the Wire Holding Clips Figure 38. Power supply and corridor lamp power connections NIRC3 The corridor lamp (NICL2) that must be used with the NIRC3 is powered directly from the 5.5V room bus power and does not require a separate 24 volt power connection, therefore the NIRC3 is not equipped with the 24 volt power outputs. IMPORTANT: Because the NIRC3 does not have 24V power outputs, the corridor lamp (NICL) should not be connected to the NIRC3.

Installation Guide teleCARE IP TD 93021US Rev A 5.5.4 Connecting Multiple Room Buses The IP room controller supports three room buses and each has a 4-pole connection terminal which is wired as described in section 5.4.1 on page 31. The connection points on the room controller PCB for the room buses are shown in section 5.3.2 on page 28.
Installation Guide teleCARE IP TD 93021US Rev A 5.5.5 Connecting LAN Cable The LAN cable has an RJ45 plug which connects to the socket on the room controller printed circuit board shown in section 5.3.2 on page 28. The LAN cable should not be guided through the wiring clips inside the room controller housing. It should be plugged directly into the RJ45 connector on the printed circuit board with enough cable to avoid straining the LAN connection.

Installation Guide teleCARE IP 5.6 TD 93021US Rev A LED Lamp Boards The LED lamp board contains four high intensity LED lamps which are used in the corridor lamp of the room controller and corridor lamp. The three pins in the back side of the board are used to connect the LED lamp board through holes in the back side of the room controller or corridor lamp printed circuit board. The room controller and the corridor lamp each accept up to four LED lamp boards. Figure 46.
Installation Guide teleCARE IP TD 93021US Rev A 5.6.1 Auxiliary Lamp Connection - NILD2 The green LED board (NILD2-GAA) has a galvanically separated output that can be used to connect to an auxiliary lamp. It has a maximum switching capacity of 0.4A at 60V peak. Max. 0.4A at 60V peak NILD2 To auxiliary power supply Figure 48.
Installation Guide teleCARE IP TD 93021US Rev A After stripping the wire, insert the wire in the appropriate opening of the connection point by pressing the wire firmly into the terminal, as illustrated below: Figure 49.

Installation Guide teleCARE IP TD 93021US Rev A The outputs L1, L2, L3 and L4 are parallel circuits to LED connections on the NIRC printed circuit board. Each external LED must be connected between the lamp connector (L1, L2, L3 or L4) and +V on the 6-pole connector. Figure 54. External corridor lamp connections of the NIRC Caution: The maximum load on each external LED circuit is 60mA. IMPORTANT: The maximum load on each external LED circuit is 60mA.
Installation Guide teleCARE IP 5.7 TD 93021US Rev A Corridor Lamp (NICL) The Corridor Lamp (NICL) is controlled by the IP room controller (NIRC only) and one IP room controller can support two corridor lamps. Each Corridor Lamp is connected to one of the three room buses of the IP Room Controller and it always has the fixed address 5.
