General Description

The Telex RadioCom™ BTR-1 UHF wireless intercom systems is the ultimate in reliable, high performance, encrypted full duplex communications.

The BTR-1 system includes the BTR-1 frequency agile base station and a TR-1 frequency agile beltpack. The BTR-1 system provides full duplex, encrypted digital communication.

The base station provides the beltpack with access to a six intercom port matrix of 2-wire systems or communication to a 4-wire intercom system. The system can interface with Audiocom® (Telex), RTS® TW, Clear-Com® 2-wire intercom systems as well as 4 wire communication systems.

In addition to the 2 and 4-wire intercom systems the base station provides connections for auxiliary balanced audio input and output, as well as relay closure and the ability for using one of the six intercom lines as a wireless only communication intercom. The system is also perfectly suited for stand-alone operation.

System Features

•Frequency agile base station and beltpacks.

•No external computer/device required to select frequencies.

•Telex Communications proprietary digitally encrypted wireless communication between the base station and

beltpack.

•AC or DC operation in the 12 to15 Volt range.

•Backlit base station LCD allows the user to easily monitor the beltpack’s status.

•The frequencies of a beltpack may be changed at the beltpack or from the base station.

•Beltpack units contained in a weather and shock resistant die cast magnesium case.

The BTR-1 has been designed for reliable, efficient operation. Operating in the 482 to 746 MHz range. The unit has expansion ability to add dozens of base stations to create a system. The high-efficiency beltpack provides up to 9 hours of uninterrupted operation using standard alkaline batteries.

•Six channels of 2-Wire intercom.

•Compatible with Audiocom® (Telex), RTS TW, Clear-Com®, RTS Matrix and other wired intercom types.

•Relay contact closure on the base station that can be activated from the beltpack.

•ClearScanä function to automatically find the best channels on which to operate.

•Base stations are table or rack mountable.

Rack Mounting

The rack mounting brackets come with each BTR-1. These brackets may be used to mount a single base station in a 19" wide rack or mount two base stations side by side in a rack. Figure 5-1 shows the three brackets that come with a base sta- tion.

1.Remove the four pan head screws (two on each side) closest to the front panel.

2.Place the double unit side bracket on the side of the base station you wish closest to the edge of the rack.

3.Replace the two pan head screws and use a third pan head screw (2 supplied with base station) to screw into the upper middle location of the bracket.

4.Place the single unit rack mount bracket on the other side of the base station.

5.Replace the two pan head screws and the other pan head screw that came with the base to secure the bracket. Screw the third screw into the upper middle hole of the bracket.

3.Replace the two pan head screws and use a third pan head screw (2 supplied with base station) to screw into the upper middle location of the rack mount middle bracket.

4.Place the dual bracket on the other sides of the base stations. Make sure the bracket is flipped so the front bend is toward the front of the base station. As you face the rack, the right base station will have the middle bracket front bend high and left base station will have the bend low.

5.Replace the two pan head screws and the other pan head screw into the upper middle hole of each bracket.

6.Use the four flat head screws (2 supplied with base station) to secure the top and bottom of the middle brackets together.

Antenna Connection

The base station is supplied with two (2) antennas. One 1/2-wave antenna for Transmit and one 1/2-wave for Receive. The antennas have TNC male connectors.

The frequency range of the antennas should match the receiver and transmitter of the base station. Match the color code on the antenna with the color code on the base station.

Attach the transmit 1/2-wave antenna to the antenna input re- ceptacle labeled “TRAN” on the right side of the rear panel. The antenna should be vertically aligned.

Attaching Transmit 1/2-Wave Antenna

Attach the receive 1/2-wave antenna to the antenna input re- ceptacle labeled “RCV” on the left side of the rear panel. The antenna should be vertically aligned.

Figure 5-5

Attaching Receive 1/2-Wave Antenna

Antenna Polarization

The Telex Wireless Intercom System is “Vertically Polarized”. This means both the transmitting and receiving antennas should operate in the vertical position.

ANTENNAS SHOULD BE VERTICAL

Figure 5-6

Vertically Polarized Antennas

Distance between Antennas

The distance between the base station’s receive and transmit antennas is not adjustable when the antennas are connected di- rectly on the back of the unit.

The antennas can be remoted for better signal path. A Telex coax assembly with remote antennas may be required. See “Accessory and Replacement Parts” section for ordering infor- mation.

NOTE: If your base station is to be located in a shielded rack mount enclosure or other poor RF location, you must remote the 1/2-wave antennas with coax assemblies. See “Accessories and Replacement Parts” section for remote mounting hard- ware.

Antenna Placement

Proper antenna placement probably has the most effect on your TELEX Wireless Intercom System’s overall perfor- mance. The following suggestions will result in optimum per- formance.

Proper placement of the beltpack can be critical. The antennas should be in the open. Bending the antennas up and placing the beltpack in a pocket, etc., will reduce system distance.

It is suggested that the unit be worn on the belt or pocket with both antenna’s vertical for best operating range and perfor- mance.

Proper Dressing of the Antennas

5-3

Keep the distance between the base station and the beltpacks as short as possible. The greater the distance, the weaker the signal. Make sure the “signal paths” between the base station and beltpacks are unobstructed. You should be able to visibly locate the base station antennas at all times for best perfor- mance.

Attempting to operate the wireless intercom system through or around walls, ceilings, metal objects, etc. will reduce system range and performance.

Operating System Near Obstructions

DO NOT - mount the base station 1/2-wave antennas on, or next to metal, such as beams, walls with metal studs, equip- ment racks, etc. This also applies to the antennas when assem- bled directly to the Base Station. This will “detune” the antennas which can result in noise or loss of RF signal at the base station.

Keeping the distance from the base station and beltpack as short, and unobstructed as possible will produce the most reli- able performance.

The base station is supplied with two antennas. This should provide satisfactory system performance in most applications. System range can be enhanced by remoting the 1/2-wave an- tennas.
