1 INTRODUCTION
1.1 PRODUCT DESCRIPTION
AT-4 represents the most recent technology for “free hands” access
solutions, that is whenever showing a ticket/card to access a gate would
become uncomfortable.
The system has been developed to read a transponder at a distance of 4
meters in a reliable manner.

2 INSTALLATION
2.1 PRECAUTIONS
The following precautions must be observed during normal use, maintenance
and repair jobs.
Make sure that the cables are connected to earth.
AT-4 must be installed and repaired only by qualified personnel.
Before removing or installing the parts, always disconnect the power
supply.
Do not modify or add components to the AT-4, if not indicated by the
manufacturer or by FAAC, in order not to jeopardize the compliance of the
system with the safety requirements.
2.2 MOUNTING INSTRUCTIONS
AT-4 can be mounted on every surface.
Locate a suitable position. Use both holes (K) on the upper part to mount the
reader.
Open the service cover to use the supporting holes located at the bottom (L).
Refer to the image below for details about dimensions and position of the mounting
positions.

2.3 ADJUSTABLE MOUNTING BRACKET
The AT-4 can be oriented into the required detection area thanks to the
adjustable mounting bracket. The mounting bracket can be fixed to square
round posts.
Fig. 2: Adjustable Mounting Bracket
The bracket can also be wall-mounted.
After having fixed the bracket, you can connect the AT-4.
The spherical part enables you to direct the AT-4 into the required direction.
After having reached the correct orientation, secure the position by means of
the Allen screw on the joint.

2.4 OPENING THE SERVICE COVER
Open the service cover to have access to the connections, check the reading
range, set the operating frequency and view the LED indicators.
Use the screws at the bottom of the device to unblock the cover and make
the lifting possible.
Fig. 4: Opening of the service cover
Note: Make sure that the screws are completely loose (or tightened when
the cover is closed again). The screws are inserted inside the plastic
structure –in this way they cannot be lost.

3 CONNECTIONS
3.1 FASTENING THE CABLES
The cables of the AT-4 are connected using EMC type cable glands.
Use a shielded cable for the power supply.
Mounting instructions:
1. Fit the nut (1), the seal (2) and the cable
gland (3) on the cable.
2. Cut the external sheath to the required length.
3. Fold the shielding screen (4) on the cable
gland and reduce the shield as shown in
Fig. 5: Shielded cable
4. Screw the nut (1) until the seal (2)
starts to come out. See Fig. 6.
Fig. 6: Tightening
For a water-proof protection a correct mounting and tightening of the EMC
connectors are of essential nature.
See Appendix A for any details on the cable glands.

3.2 CONNECTIONS
The cables inside the AT-4 are connected by means of connectors with
spring terminals which make for an easy and intuitive use.
1. Remove the sheath from the cable for approx.
9 mm (0.35 inch).
2. Using a screwdriver push downward to free
the cable passage. Use a screwdriver with
thin flat bit.
3. Fit the cable into the connector terminal.
4. When the screwdriver is removed, the cable
remains blocked thanks to the spring
connector.
5. Check if the cable is correctly fixed by drawing
it gently.

Note 1: One cable only for each terminal.
Note 2: Usually there is no need to use pins. However, if this is necessary,
you can use them provided that they are correctly crimped.
See Appendix A for the recommended cable section.
