Installation Instructions ASC 2 Supervision Card Model ASC 2 Audio Supervision Card Siemens Industry Inc supervises the of one primary amplifier and one amplifier in an MXLV System The compares the amplifier output to the input from the OMM 1 If they do not a trouble indicates on the MKB 2 The output may be connected in Style or Style Z The audio output can be con to the ZC zone card series the primary amplifier fails the ASC 2 input signal for the failed amplifier to backup amplifier and the backup amplifier output to the channel formerly served by the amplifier card provides the means for multiple cards that supervise many amplifi to share one backup amplifier 1 Module Board primary amplifier gets its input from the terminal block adjacent to the OCC 1 Control Card module The amplifiers be assigned to any one of the three audio by setting switch S2 on the ASC 2 the switch setting instructions in the section to set the desired input selections ASC 2 occupies one of eleven sub of the OCC 1 When installing an card use the CSG M configuration to locate the address of the card Use S1 to set a unique address for the card as described in the INSTALLA section additional information on the Voice refer to the MXLV Manual P N Industry Inc Technologies Division Park NJ 315 092085 11 Building Technologies Ltd Safety Security Products Kenview Boulevard Ontario 5E4 Canada

side marked To close a slide switch push the to the side marked ON Switches S1 and S2 and Jumpers J1 and J2 on the ASC 2 2 Set switch S2 for proper supervision of the To set the ASC 2 for 70.7V RMS Refer to No 10 below Place the J1 jumper in the right hand po with the gold plated edge facing up Check that fuse F1 is 2A If the backup amplifier is an EL 410C D the jumper J2 in the upper position the gold plated edge facing up This the backup amplifier input side to the MXLV power supply place J2 in the lower position the data sheet of your amplifier for information Do NOT install the card in its edge connector ALL OMM 1 field wiring is completed checked for shorts opens and other Refer to the Wiring Checkout Chart the card in its protective bag if the is not complete Place the user key from the installation kit in OMM 1 card edge connector for the This prevents the installation of any card type in the ASC 2 slot Two keys prevent reverse installation of the card are factory installed in the OMM 1 edge See Figures 3 and 4 Incorrect settings can cause of the backup amplifier to transfer SWITCH S2 input 1 Riser 2 Riser 3 USED USED X Enable backup amplifier supervision Disable backup amplifier supervision Closed or ON O Open or OFF Check the system wiring plan to be certain amplifier and riser assignments then switch S2 dipswitches SW1 and SW2 following the table above Refer to 2 for the location of switch S2 Close SW5 on switch S2 if this ASC 2 card the backup amplifier If one amplifier is shared by more than ASC 2 card open SW5 of S2 on all cards except the one that the backup amplifier Refer to Figure 2 again note the position of and J2 To set the ASC 2 for 25.2V RMS Refer to No 10 below Place J1 jumper in the left hand position the gold plated edge facing up Check that fuse F1 is 6A 3 the User Key in the OMM 1 4 of the Key for the one backup amplifier is shared by more one ASC 2 connect terminal 3 of the block on the primary ASC 2 to 3 of the terminal blocks of all other cards that share the same backup the system has NO backup amplifier a jumper across terminals 3 and 4 After completing and checking all field wiring the card in its card edge connector components on the board must face the terminal block where the wiring Press the card firmly in place to sure it is seated properly in the edge 2 Use single conductor wire for connections wire length
