PROXIMITY CARD READER
CZ-EMM2
cz_emm2_en 08/08
The CZ-EMM2 proximity card reader – also referred to as the “SATEL reading
head” – is a device used in access control systems. It is designed for reading
the proximity card code. The reader interfaces with the CA-64 SR expander of
proximity card readers.
1. READER DESCRIPTION
The head transmits data (i.e. the read-out card code) in the EM-MARIN format.
It has a built-in two-color LED indicator (emitting red and green light) and
a buzzer, which serve the signaling purpose. The signaling mode as well as
situations when the signaling is triggered depend on the control device the
reader is connected to. Electronic circuits of the head are coated with epoxy
resin to protect them against moisture. A multicore cable for connecting the
reader to the control device is led out from the head housing (see HEAD
CONNECTION).
2. SUPPORTED CARDS
The reader supports EMCARD type cards, available from the head
manufacturer, which are designated by the KT-STD-1 symbol in SATEL's
business offer.
3. CARD READING
For the head to read out the coded number of a card, the card must be brought
near to the reader within a distance of approx. 10cm for at least 0.5s. When
read out, the card number is sent to a control device (e.g. CA-64 SR expander)
which signals that the card code has been read out (with the head LED/buzzer)
and initiates appropriate actions. A next card code can be read immediately
after moving the previous card away from the reader. In case of a failure to
remove the card away from the reading zone, the card code will be repeatedly
read and sent to the control device. The control device can take different
actions, depending on whether the card has only been brought closer for 0.5s,
or held still for approx. 3s.
4. INSTALLATION
The CZ-EMM2 proximity card reader is designed for indoor installation. The
head should be mounted straight on the wall, vertical installation being
recommended. The reader should not be exposed to a direct contact with water.

Where several heads are used in the system, the distance between them
should be at least 50cm.
Note: If the head is mounted on metal surface, the reading range will be
reduced.

5. READER CONNECTION
The reader hookup is to be made with the use of a typical cable (e.g. DY 8x0.5)
according to the table below. The length of the cable connecting the head with
the control device is not to exceed 30 meters.

Table 1. Connection of CZ-EMM2 reader cables to control device terminals.
Note: The terminals designated TMPA and TMPB appear on the electronics
board of the CA-64 SR expander in version 1.6. When connecting the
readers to an older version of expander (1.5 or earlier), disable the
READER CONTROL option in the expander settings. The white cable of the
reader can be left unconnected, or connected to the common ground.
You can also connect this cable directly to the control panel so as to
monitor the reader presence. The cable is connected to the common
ground in the reader via a 2.2kOhm resistor. Program the zone to which
the cable is to be connected in the control panel as the "24H tamper" and
match the detector configuration accordingly.
