To prevent damage to the loudspeakers due to frozen moisture inside the voice coil gap each Intellivox 15 equipped with a frost protection If the ambient temperature drops below a certain threshold the internally generated pilot tone for the frost protection will be activated The aforementioned ambient SPL temperature sensor should be installed for this function to operate properly The switching threshold and hysteresis can be adjusted through the RS 485 interface AXYS Intellivox installation manual 2 3 Wiring and connections 2 3 1 Mains power Be sure that the mains voltage stated on the unit complies with the local standard before connecting the Intellivox to the mains supply The maximum power consumption of the Intellivox 2c model is 450 VA this figure however is different from other models refer to the appropriate datasheet The Intellivox is equipped with a 3 pin IEC type mains inlet fuse holder If the fuse needs to be replaced only replace with the same value The IEC cable socket which 15 supplied with the unit is only suited for use with stranded wires The preferred and most straight forward solution is to feed the Intellivox from a mains power outlet situated nearby the unit using an off the shelf 3 x 0 75 mm AWG 18 IEC mains cable If the mains outlet is located directly behind the Intellivox it should be recessed to be able to mount the unit flat to the wall In case it is necessary to make a connection fr

For this reason the sensor should be kept away from direct sound sources such as talking people outlets of the air conditioning system or other loudspeakers The implemented software protocol freezes the volume setting when an audio signal 15 present in order to prevent hunting of the column s gain setting caused by its own acoustical output All relevant autogain parameters can be adjusted by means of the RS 485 interface In practice the most favorable sensor locations are walls or ceilings height gt 3 m within a range of 25 m of the corresponding Intellivox see also chapter 3 4 If the ambient temperature is expected to exceed 40 C an external fan should be connected to ensure proper operation of the Intellivox under all circumstances For this purpose an external 24 V relay should be connected to the terminal block marked Fan Relay Because of the limited drive current an external relay must always be used to switch the fan do not connect a fan directly to this terminal The external relay if connected will be engaged if the heatsink temperature exceeds the threshold The fan should be mounted on a location ensuring sufficient airflow along the heatsink In case the Intellivox 1s installed outside or in another environment with a high expected humidity the electronics should be treated with an insulation substance to prevent defects due to condensing moisture If specially ordered this can be done during the manufacturing process

L and temperature measurement Although the unit is able to operate normally without the sensor it is needed when the auto gain function or the frost protection is used The temperature is measured by a NTC resistor By means of a software correction table the non linear resistance characteristics of the NTC are compensated and converted into a degree scale The SPL is measured by an electret microphone rectified and converted to a dB scale The microphone is powered by the amplifier module through the connector Location of the sensor Both NTC and microphone are mounted in a single compact enclosure which can be located at a certain distance from the column In most situations the best location is determined by the microphone see also chapter 2 2 The auto gain will only work correctly if the diffuse ambient noise level is used as a reference This means that the microphone should be kept away from direct sound sources such as talking people outlets of the air conditioning system or other loudspeakers The implemented software protocol freezes the volume setting when an audio signal is present in order to prevent hunting of the column s gain setting caused by its own radiated acoustical energy D Although the circuit of the combined sensor is not complex the specific characteristics are very important for a correct interpretation of the measured values For this reason it is strongly advised to use the appropriate factory tested sensor see

25. ht of the acoustically active part of the column is optimized while during installation the issue of interest is the physical mounting height of the column Unfortunately there is no fixed relation between these two because the exact position of the acoustical part of the array inside the enclosure is depending on the location of the electronics module In the standard version of the Intellivox the electronics module is mounted in the lower end of the enclosure as it is shown in Fig 1 Other versions however may have the electronics module mounted at the top end Because of the extreme tight vertical radiation pattern of the Intellivox a small deviation from the calculated acoustical mounting height may cause severe degradation of the expected performance For this reason the designer 15 advised to define two mounting heights a physical mounting height which refers to the physical bottom side of the enclosure and an acoustical mounting height referring to the on axis location of the loudspeaker at the lowest position Although the physical mounting positions are of primary concern to the contractor a quick check of the acoustical height during installation will confirm the integrity of the original acoustical design Connector compartment Electronics module Figl Intellivox 2c shown without front grill AXYS Intellivox installation manual
