Power from the controller to the transceiver is provided via RS422 (18 
AWG, single-pair, stranded, tinned copper) using 12 VDC. The power 
wire is connected to pins 5 and 6 on the transceiver port. Connect the 
positive 12 VDC to pin 5 and ground to pin 6.
Wire for communications must be 24 AWG, 2-pair, stranded, tinned copper, 
individual shield, drain wire, low capacitance wire. 

Communication connections on the transceiver are made on pins 1, 2, 3, 
and 4. Communication to the XT occurs on pin 1 (TX+) and pin 2 (TX-). 
Communication from the XT occurs on pin 3 (RX-) and pin 4 (RX+). Wiring 
connections are shown on page 2.

After wiring is completed, push the learn button once to verify power. 
The LED will light if power is connected correctly. The LED will go off 
automatically after a few seconds. This will also automatically learn the 
transceiver to the Falcon XT.

Prior to mounting the transceiver, write down the serial number of the 
device. This number will be needed during programming. Use the following 
guidelines when mounting the transceiver.

Mount the unit in an area protected from the weather

• 

Mount the unit as high as possible on the site (such as near 

• 

the roofl ine) using the provided mounting screws or appropriate 
mounting hardware for the application
Mount the unit to a solid, nonmetal surface 

• 

The unit is weather-resistant

• 

Warning: Do not try to add length to the antenna to 
extend the transceiver’s range as this will cause the 
system to become inoperational and/or will exceed 
FCC requirements.

On large sites, multiple transceivers may be required to provide adequate 
communication coverage. Up to 8 transceivers can be installed on one site 
and learned to one Falcon XT, with up to 1024 overlocks per transceiver 
(allowing a maximum of 8192 overlocks per site). 

While 24 AWG wire is the minimum recommended, the wire gauge may 
need to be increased depending on the length of wire to be run and 
the number of transceivers to be used. The wire used must ensure that 
adequate voltage is available at the last device in-line. The minimum 
allowable voltage at the device furthest from the Falcon XT is 7.5 V. 

NOTE: Ensure that the wire run does not reduce the voltage to less than 7.5 V 
at the device furthest from the Falcon XT.

The transceiver is a bi-directional transmitter that facilitates communication 
between the Falcon XT access control system and overlock devices used to 
control individual doors. Communication occurs over multiple RF channels 
concurrently to ensure constant communication capability. When the 
transceiver receives input from the XT, it sends that signal to the overlock 
device to control the overlock function. The transceiver continually scans 
for a signal from the overlock and if a determined period of time elapses 
with no signal, the transceiver sends an alert, which shows up on the main 
screen of the overlock management software.

Transceiver service alerts are managed in the overlock management 
software. In the software, go to Tools\Manage Transceivers to view and  
clear alerts.

NOTICE: To comply with FCC and or Industry Canada rules (IC), adjustment 
or modifications of this receiver and/or transmitter are prohibited, except for 
changing the code setting or replacing the battery. THERE ARE NO OTHER 
USER SERVICEABLE PARTS.

This device complies with part 15 of the FCC rules. Operation is subject to the 
following two conditions: (1) This device may not cause harmful interference, 
and (2) This device must accept any interference received including interference 
that may cause undesired operations.
