Caution: Use extreme caution and follow instructions carefully. Caution: Bright LEDs behind translucent dome cover. High brightness light is produced by the LED boards that are placed onto the NICL4 circuit board. Do not stare into the light when the translucent dome cover is removed.
Corridor Lamp 4 Description The Corridor Lamp (NICL4) is controlled by the room controller (NIRC4 only). Each room bus of the room controller (NIRC4) can support up to four NICL4 corridor lamps. The NICL4 corridor lamp supports up to 4 LED boards (NILD2, NILD4–RGB) behind a translucent dome cover.
Installation Installation The NICL4 has an IP40 ingress protection. The areas in which NICL4s 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 NICL4 is to be installed.
The Corridor Lamp 4 (NICL4) Installation Instructions contain important instructions for use during installa- tion and maintenance of the NICL4. To ensure a safe working environment during the installation and operation of the NICL4, the following safety symbols appear throughout this document to indicate dangerous conditions and important safety instructions.
Mounting Mounting The base of the NICL4 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.
The cables should enter through the knockout holes in the base of the NICL4. Do not distort or twist the base when mounting it to a wall. If the base is distorted, the NICL4 dome cover will not fit properly and may fall off.

Place the base (with the knockouts removed) over the holes, insert the screws, and then tighten. Pull the cables through the knockout holes and follow the directions in the following sections. Caution: The NICL4 must be mounted in a way that the module is firmly attached to the background.
Before attaching the PCB to its base, make all wire connections and DIP switch settings. Be sure that required cables are properly connected. The following figures show the locations for each cable. Figure 2. NICL4 Circuit Board - Front Legend (1) LED lamp (NILD2, NILD4–RGB) connections...

DIP switch settings for corridor lamp ID selection To set a DIP switch: Set the DIP switches to the ID (0 to 3) chosen for the NICL4. Use the ID table above to determine the correct positions (ON or OFF) for the DIP switches.
Terminating and Mounting the Room Bus RJ45 Connectors The NICL4 includes two active room bus RJ45 sockets. Crimp the RJ45 connector(s) to the room bus cable (s) using the Ethernet T-568B termination color scheme. The following figure shows the correct pinout for terminating the active room bus cables.

To place the NILDx LED board(s): Insert the LED boards into the NICL4. The pins on the LED lamp board are not in the centre of the board, therefore it is important to make sure that the LED lamp board lines up with the guide marks on the corridor lamp PCB when the pins are inserted.
