User manual ASL INTERCOM TS 120

[. . . ] It is not necessary to provide rear support by extra bracing or shelving. Adequate ventilation must be provided by allowing sufficient space around the sides and rear of the unit to ensure free circulation of air. The power supply is located on the rear of the unit, and after a period of time it will feel hot to the touch. This is quite normal, and should be no cause for alarm.

User Manual TS 120 / Issue 1 2000 ASL Intercom, Utrecht, Holland. 5 8. 0 CABLING For the THEATER Series system the interconnecting cables are of the shielded two-conductor microphone cable type and the intercom line connectors are of the XLR-3 type. The signals are on XLR pin 3, DC power is on XLR pin 2. XLR pin 1 is connected to the shield of the cable which functions as the common return for audio and power. Since the DC signals are transferred in an unbalanced way, certain rules have to be obeyed when installing the cables of an intercom network. This is to minimize power loss and the possible effects of electromagnetic fields. These rules are: Use high quality (multipair) cable. For interconnecting user stations, power supplies and accessories in an ASL Intercom network, use high quality shielded two-conductor (minimum 2x 0. 30 mm2) microphone cable only. In case of a two channel intercom network, use high quality microphone ' multipair' cable only, each pair consisting of two conductors (minimum 2x 0. 15 mm2) with separate shield. Multipair cable should also have an overall shield. Use flexible single and multipair microphone cable instead of cable with solid cores, especially when the cable is subjected to bending during operation or installation. The screen of each separate microphone cable and/or the screen of each single pair in a multipair cable, should be connected to pin 1 of each XLR-3 connector. Do not connect this cable screen to the metal housing of the connector or to metal wall boxes (outlets). Cable trunks, connection boxes and overall multipair cable screen to clean earth. [. . . ] Avoid using mains outlets which also power dimmer controlled lighting systems. In case of more complex installations, don'hesitate to t contact us. Please send us a block diagram of the planned network with a list of all user stations and their positions, and we are happy to advise you on cabling lay out. 6 User Manual TS 120 / Issue 1 2000 ASL Intercom, Utrecht, Holland. 9. 0 WARRANTY 10. 0 TECHNICAL SPECIFICATIONS TS-120 POWER CONSUMPTION Max LINE DRIVER max. output current output impedance DIMENSIONS AND WEIGHT width height depth weight GENERAL SYSTEM Mains voltage: SPECIFICATIONS 90 - 240 V AC (auto select) 50/60 Hz.
