USING TELSON 3000 AS A TELEPHONE SYSTEMIn this case, the TELSON 3000 central unit must be wired to a PABX. Each telephone station is connected to the PABX andcan access to its programmed features, including the trunk connection. The user can decide freely if he wants to use thestation as a telephone or as an intercom, dialing “0” to operate onto the telephone PABX system or “9” to operate onto theintercom system.CONFIGURATION EXAMPLESLOUDSPEAKERS NETTwo configurations may be allowed:With a local decentralized amplification, based on the loudspeakers withbuilt-in amplifier, designed and manufactured by LE LAS for meeting all theindustrial demands.In addition to the standard amplified loudspeaker, LE LAS offers also theamplified and self-adjustable loudspeakers (RED series), which detect the noiseof the surrounding area and adjust automatically their own audio output inorder to compensate the noise level.In addition, the loudspeakers net is really flexible and modular, becauseeach loudspeaker has an own amplifier and the customer doesn't calculateany additional power and/or he has not to change the central power amplifierfor increasing the audio power in the field.Furthermore, the loudspeakers net have the maximum level of reliability andredundancy, because in case of fault on one amplifier, the user looses only oneloudspeaker.With a centralized amplification, which is integrated in TELSON 3000 whenLoudspeakers net are already existing.Typically, the central amplifiers and each loudspeaker have the output over100V line transformers.The 400W powers amplifiers by LELAS are equipped with own power supply,balanced output, protection against transients, activation drivers and adiagnostic circuit that supervises the loudspeakers lines.CONNECTION SCHEME
