The system has been developed to read a transponder at a distance of 4 meters in a reliable manner. FAAC S.p.A. Via Calari, 10 – 40069 – Zola Predosa (BO) - Italy Page 3 of 25...
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.
AT-4 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.
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. FAAC S.p.A. Via Calari, 10 – 40069 – Zola Predosa (BO) - Italy Page 6 of 25...
AT-4 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.
AT-4 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 screwdriver 2.
AT-4 3.3 POWER SUPPLY AT-4 requires a DC 12 – 24V power supply. The max. current consumption is 1A @ 12VDC, 0.5A @ 24VDC. Connections: 12 - 24VDC. Note: The electrical connection is protected by means of a self-resetting fuse.
Note 2: Activate the RS232 interface by setting the DIP-switches SW1-2 to ON. See chapter 5.2 for further details. Fig. 9: RS232 wiring FAAC S.p.A. Via Calari, 10 – 40069 – Zola Predosa (BO) - Italy Page 10 of 25...
AT-4 3.5.2 DISABLED READING AT-4 reading can be completely disabled by means of the RDIS input. This input is commonly used together with a sensor (e.g. with a magnetic loop) that detects the presence of a vehicle. Use a voltage-free contact to connect the 5V to the RDIS input.
Tamper (common contact) Operation of the contacts: Max. current 50 mA (0.5 Volt voltage drop) Voltage +24 VDC Tamper Fig. 13: Tamper switch FAAC S.p.A. Via Calari, 10 – 40069 – Zola Predosa (BO) - Italy Page 14 of 25...

AT-4 7 SELECTING THE FREQUENCIES The AT-4 reader operates in the frequency band of 2.45GHz. When two or more readers are within a 15 m radius, they should be set to different operating frequencies. The selected frequency must observe the local radio regulations.
8 READING RANGE (SENSITIVITY) 8.1 PRINCIPLE The reading range of AT-4 can be controlled by the built-in sensitivity function. When the power of the received signal is below the sensitivity level, no identification is possible. The power of the received signal becomes higher when the transponder comes close to the reader.
