Chamberlain Wireless Products Inc. XCVR Manuale Utente

The T1000 transceiver is designed to allow communication between 
the AccessMaster Overlock and the Falcon XT access control system. 
The T1000 transceiver provides a secure, reliable wireless mode of 
communication without the need to run excess wiring throughout the site.  
The T1000 is designed to work only with the R1000 repeater and/or the 
OL1000 overlock device.

Remove the bottom panel of the T1000 transceiver to view the power and 
communication pins.

Power from the XT 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.

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

Mount the unit within 50 ft of a power source 

• 

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

Mount the unit to a solid, nonmetal surface 

• 

The unit should be halfway between the 

• 

devices that need to communicate.

The unit is weather-resistant

• 

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

On large sites, multiple repeaters may be required to provide adequate 
communication coverage. Up to 8 repeaters can be learned to one 
transceiver, with up to 64 repeaters to one site. 

The R1000 repeater extends the range of the T1000 transceiver to cover 
larger areas. Repeaters should be located throughout the site in such a way 
that coverage overlaps slightly to provide the most complete coverage. Up 
to 8 repeaters can be programmed to communicate with one transceiver. 

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.
