4. included with the ANS 500 product Additional microphones may be purchased separately The control unit is capa ble of supporting up to four 4 microphones wired in parallel however if the sound level increases in one area monitored by a microphone the resulting page signal will be boosted in all areas supplied by the amplifier Wire runs between the control unit and microphones consist of two conductor AWG20 and reach 2 000 feet with no appreciable loss of signal strength Installation Precautions WARNING Do not apply power to the control unit until all connections have been made and double checked Read and understand all installation instructions before you install the ANS 500 It may be necessary to retap speakers at their highest level and or replace the amplifier with a more powerful unit Refer to the section titled Amplifier Connection for information Set System Response Delay Time The ANS 500 is equipped with a jumper to set the system response delay time The time can be set to FAST approximately 1 second or SLOW approxi mately 25 seconds To set the time place the jumper block as shown below Jumper block set in Slow position Note The ANS 500 is shipped with the jumper in the Slow position Jumper block set in Fast position Microphone Module Installation Locate the microphone module s in an area central to the noise producing source It can be mounted in a vertical or horizon
5. tal position The module should face the direction of the highest noise leve source Make connections as shown in the wiring diagrams Amplifier Connection WARNING Make all connections with the power off If the amplifier used with the ANS 500 is connected to the speaker system using the 70V or 25V output terminals you should tap the loudspeakers for their high est power level This will allow higher output without overdriving the trans form r when the ANS 500 provides higher gain Afier tapping the speakers calculate the total wattage required by adding the wattage of all speakers If the total wattage exceeds the output wattage of the paging amplifier you will need to replace the unit with an amplifier of sufficient power The replacement amplifier should provide approximately 20 headroom to allow for future expansion and to extend the life of the amplifier Operation amp Adjustment Apply 24 VDC to the ANS 500 Bogen Model 500 5 Tum SENSITIVITY control to full counter clockwise position min Tum the amplifier power switch to the ON position 3 With the background noise at its normal level adjust the amplifier output for the desired level from speakers 4 Turm on all noise producing equipment in the area of the microphone to achieve the maximum ambient noise level 5 While making a page slowly turn the SENSITIVITY control clockwise until the page is at the desired level above the noise WARNIN
