B.	This product shall be manufactured by a firm whose quality system is in compliance with the I.S./ISO 9001/EN 29001, QUALITY SYSTEM.

2.02 PRODUCT DESCRIPTION
A. The product specified shall be a code merger and line driver unit specifically designed to combine the biphase control code outputs generated from two (2) Bosch Security Systems devices. The unit provides thirty two (32) separate biphase outputs where each may be wired in a “star” or “daisy chain” configuration. 

2.03 CODE MERGER and LINE DRIVER REQUIREMENTS
A. The product specified shall be a code merger and line driver unit specifically designed to accept the biphase control code outputs from up to two (2) Bosch devices, and, in turn, generate 32 separate biphase outputs to equipment capable of receiving Bosch biphase control codes. The same data shall be generated from all outputs making it irrelevant as to which output is used.

B. The code merger and line driver specified shall generate 32 separate biphase outputs where each output may be wired in a “star” or “daisy chain” wiring configuration. When wired in daisy chain configuration, each output shall be capable of driving up to 8 remote devices. The code merger shall provide removable screw terminal blocks to connect shielded twisted pair wire (Belden 8760 or equivalent) between its outputs and the biphase code receiving devices. 

C. Each of the biphase outputs of the code merger and line driver shall be capable of transmitting a distance of up to 5000 ft.(1.5 km) when using 18 AWG (1 mm2) shielded twisted pair cable.

D. Multiple code merger units may be cascaded together to obtain additional biphase control code outputs.

E. Input connections to the specified code merger and line driver unit shall be via standard 9-pin D-type connectors. Two 2-meter (6 ft) data cables to connect between the biphase control code generator devices and the code merger unit shall be provided by the manufacturer. 

F. The Code Merger and Line driver specified shall accept biphase code from the following Bosch equipment:
1) Allegiant main CPU bays.
2) LTC 8568/00 Signal distribution Units.
3) An output from another specified Code Merger Unit.
4) Digital recorders such as the Divar, DESA, and DiBos Series.
5) LTC 8780, LTC 8784, and LTC 8786 Series Data Converter Units.
6) LTC 5136 AutoDome Controllers. 

G. The Code Merger and Line Driver specified shall provide compatible biphase code to the following Bosch equipment:
1) Allegiant Satellite Systems
2) AutoDome Series cameras
3) Conventional Allegiant Receiver/Driver Units
4) Allegiant LTC 8770 Relay Follower Series

H. Biphase connection points shall be provided as screw terminals on four (4) easily removable terminal blocks. Stripped 18 AWG (1 mm2) shielded twisted pair wire shall be easily inserted and tightened in the screw connections.

I. The product specified shall be provided in an indoor rated enclosure designed to fit a standard EIA 19” rack.
