3. Installation
The device should be installed by qualified personnel.
Disconnect power before making any electrical connections.
The reader is designed for indoor installation.
The reader should not be exposed to direct contact with water. If the reader is to be
exposed to contact with water, install it as shown in Fig. 3 (the LED should be at the
bottom).
If the reader is installed on a metal surface, the card reading range will be reduced. To
avoid this, you can use the CZ-EMM-POD pad, which is available in SATEL's product
range.
Two readers connected to the same device can work when situated a short distance
from each other. However, the distance from a reader connected to another device or
a device with built-in reader (e.g. a keypad with reader) should be at least
50 centimeters.
If you need an extra cable to make the connections, use an unshielded non-twisted cable.
The total length of the cable connecting the reader to the device should not exceed
30 meters.
1. Remove the reader cover.
2. Place the enclosure base against the wall and mark the location of mounting holes. The
recommended mounting method is shown in Fig. 2. Fig. 3 shows how to install the reader
when it is exposed to contact with water.
3. Drill holes for wall plugs (anchors) in the wall.
4. Make a hole in the wall for the reader cable and run the cable through it.
5. Using wall plugs (anchors) and screws, secure the enclosure base to the wall. Select wall
plugs specifically intended for the mounting surface (different for concrete or brick wall,
different for plaster wall, etc.).
6. Replace the cover.

4. Using
Present the card to the reader so that the reader can read the card code. The card code will
be sent to the device to which the reader is connected. That device will decide what function
to run.
The device to which the reader is connected can distinguish between presenting the card
(one-time reading the card code) and holding the card (the card must be held in front of the
reader for about 3 seconds, and its code will be read repeatedly during that time). Another
function can be activated by presenting the card, and another by holding it.
The way the visual (LED) and audible (sounder) signaling works depends on the device to
which the reader is connected.
