Satel CZ-EMM2 Manual

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.

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
).

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.

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.
