PROXIMITY CARD READER

CZ-EMM2

cz_emm2_e 04/06

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. R EADER 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 H EAD

CONNECTION ).

2. S UPPORTED 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. C ARD 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. I NSTALLATION

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. R EADER 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

R EADER 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.
