Mounting
INSTALLATION GUIDE
Card Reader (NUCR-HE)
3 Mo nting
The NUCR has an IP40 ingress protection. The areas where NUCRs are to be installed must be clean, dry,
and weatherproof. The walls should be finished (painted, wall papered, tiled, etc.) before the devices are
installed.
The base of the NUCR mounts to backboxes using an array of holes that allow for mounting on various
backboxes.
Caution: To prevent a fire hazard because of dust buildup inside the NUCR, regular
inspection and/or cleaning of the NUCR is required.
Take proper measures to avoid spreading dust and other particles when applying
maintenance to an NUCR that is mounted inside a clinical area.
3.1 Mo nt the NUCR onto a backbox
When Installing the NUCR with the tamper function active, a backbox must be used. The NUCR comes with
a special plastic plate for the tamper functionality.
Note that mounting the card reader on or near metal surfaces can negatively influence the RFID
card reader performance.
1. For EU-style or UK-style backboxes, remove the screws from the backbox.
The screw distance for the backboxes must be 60mm (2.36 in.).
2. Place the plastic plate over the backbox with the arrow pointing up (item 1).
The protrusion must point forward (item 2).
3. Pull the room buses through the plastic plate of the NUCR.

See 5 Terminating the Room Bus RJ45 Connectors, page 7.
4. Insert the room buses into the RJ45 connectors on the rear side of the NUCR.
5. Place the Module over the plate and use the backbox screws to mount the NUCR.
6. Position the module and plate until its top is level.
7. Tighten the screws until they are snug. Do not overtighten.

Mounting
INSTALLATION GUIDE
Card Reader (NUCR-HE)
For the tamper switch to function, the module should be mounted right on the plastic plate.
The working distance of the switch is approximately 1mm (0.04 in).
8. Place the two provided screw caps over the screw holes. Orient them correctly. The caps have a small
protrusion that fits neatly into the small indentation of the module, see detail below.
9. Perform a test with an accepted card and verify that the LED and buzzer function correctly.
Only in a correctly configured system will a call or presence generate an alert on display
devices such as corridor lamps.

• Insert a small flat tipped screwdriver next to the cap (item 1).
• Twist the screwdriver and pop out the cap (item 2).
2. Remove the 2 screws.
3. Pull the module gently away. The module is still connected to the room buses.
4. Disconnect the room buses from the module.

Terminating the Room Bus RJ45 Connectors
INSTALLATION GUIDE
Card Reader (NUCR-HE)
5 Terminating the Room B s RJ45 Connectors
The NUCR 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.
RJ45 connector for active room b s cable
For easy mounting of the RJ45 connector, use Easy RJ45 connectors that allow feeding excess wire length
through the connector. When crimping, the excess wire length will be cut automatically.
(Easy) RJ45 connectors are not included and must be ordered separately.
Easy RJ45 connectors require a dedicated crimping tool (not included) that includes a cutting
mechanism to cut the excess wire when crimping the connector on the cable.
RJ45 Connector on Cat 6/7 Cables
Caution: Cat 6/7 cables may be too stiff to handle using the normal terminating procedure,
which can result in putting to much stress onto the switch module when it is mounted onto
the backbox.
Therefore remove an appropriate portion (1) of up to 15cm (6in.) of the outer jacket before
crimping the RJ45 connector onto the Cat 6/7 cable.
Note that the individual twisting of the wire pairs should remain intact up to the RJ45
connector.

Card Reader (NUCR-HE) Connecting to a door
6 Connecting to a door
The NUCR offers two auxiliary functions: a relay circuit for switching an external device, such as an
electrically operated door lock, and a pair of connections for monitoring, such as door open detection. The
relay connection is a potential-free contact (“normally open” / “normally closed”) and the monitoring
connections consist of ground (GND) and two return lines (IN0/IN1).

Legend
1. DC electric door lock. A surge dampening diode is needed only with DC power
2. Electric door lock power supply (max. 30Vdc)
3. Door monitoring contact (NO/NC)
The door lock relay and monitoring inputs must be configured in the vNISM GUI. See the Configuration
Manual (TD93442EN) for details.
