teleCARE IP
6.12 Card Reader Module (NICR)
The Card Reader Module (NICR) is a single switch module suitable for use in the teleCARE IP system. It
is an RFID device operating in the 13.56 MHz frequency range used in combination with contactless
smartcards. It is connected to the teleCARE room bus,
in the same way as other peripherals and it has a fixed room bus address of 6.
Figure 25. Card Reader (NICR)
The NICR is used in combination with a doorside module to allow attendants and staff members to
register their presence through the smart card. It can also be used for access control using authorized
smartcards to open electrically locked doors.
The NICR should be mounted in an accessible location (usually next to the entrance door of the room)
so that the smartcard can be held close to the reader when the attendant or staff member enters or
leaves the room.
The NICR will read the smartcard when it is at a distance of up to 3/4 in. (20mm) in front of the card
reader. When a card is detected a buzzer in the NICR sounds.
The NICR has a red LED and a green LED which shine through the cover plate. The green LED shows
when an authorized card is detected and the red LED shows when an unauthorized card is detected. A
continuously flashing red LED indicates that an error has been detected by the watchdog.
The NICR offer 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 “normally open” volts-free contact and the monitoring connections consist
of ground (GND) and a return line (IN).
A tamper alarm switch is mounted on the NICR printed circuit board and this detects when the card
reader is removed from the backplate. The system can be configured, using the System Manager, to
generate an alarm call when the tamper switch is operated.
The NICR requires a single backplate which must be ordered separately. A spacer with installation kit is
also available for surface mounting the NICR.
Note: The tamper alarm function is not possible when the spacer is used.
