PROXIMITY CARD READER
CZ-EMM
cz_emm_en 08/08
The CZ-EMM 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 codes. The reader interfaces with the CA-64 SR expander of
proximity card readers.
1. DESCRIPTION OF THE READER
The reader 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 are used for signaling. 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 reader 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 reader housing (see READER
CONNECTION).
2. SUPPORTED CARDS
The reader supports EMCARD type cards, available from the reader
manufacturer and designated by the KT-STD-1 symbol in SATEL's offer.
3. READING THE CARD
For the reader to be able to read the coded number of a card, the card must be
brought near to a distance of approx. 14cm from the reader for at least 0.5s.
When read out, the card number is sent to the control device (CA-64 SR
expander) which indicates (with the reader LED/buzzer) that the card code has
been read out and initiates appropriate actions. A next card code can be read
immediately after moving the previous card away from the reader. If the card
fails to be moved 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-EMM proximity card reader is designed for indoor installation. The
reader 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 readers are used in the system, the distance between them
should be at least 50cm.
Note: Do not mount the CZ-EMM reader directly on the metal surface. For
installation on metal surfaces, use the special CZ-EMM-POD pads.
5. READER CONNECTION
The reader should be connected with the use of a typical cable (e.g. DY 8x0.5)
according to the table below. The length of the cable connecting the reader with
the control device is not to exceed 30 meters.

Table 1. Connection of CZ-EMM 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.
