s Instructions ZAM 180 Amplifier Module 180W 500 035600 S24235 B6 A5 70V Installation Instructions for North America Model ZAM 180 from Siemens Industry Inc is a CAN data bus module contains two speaker zones and one audio amplifier capable of operating 25 150W or 70 180W VRMS two speaker zones can be wired operate as either a single Class A or a single Class B zone or as Class B zones independently to provide split zone or speaker zones ZAM 180 can also be used as a amplifier to serve as a backup other ZAM 180 amplifiers in a 1 to backup or 1 to many backup ZAM 180 mounts at the back of enclosure of the system and of the total space of the Plate Class D audio power with 180W RMS power all efficiency about under full load is supervised for is protected against short circuit over and over modulation 1 features are as follows Edition 10 315 035600 10 lines are supervised for open short circuit and ground fault ZAM 180 is micro controller controlled FPGA controls the digital audio data stream ASI Bus transmitted the DAC NET update via PMI PMI 2 PMI 3 XLS FCM2041 U2 Desigo Fire Modular FCM2041 U3 Cerberus PRO Modular ZAM 180 receives its control and communication data from the DAC NET sends its status data to the DAC NET via the CAN Bus Therefore it takes sub address of the DAC NET Connections transmission of compressed or audio data from the DAC to the ZAM 180 is realized via ASI Serial Interface Transmission on ASI is executed with a timeslot and is synchronized with Frame Bit Synchronize Signals Via control on the CAN Bus the timeslots are to each ZAM 180 Each ZAM is configured to listen to its timeslot local audio input is provided to connect external audio source The audio input isolated on the ZAM 180 to prevent loops The local audio input is via an external contact The of this input will be executed by amplifier directly The ZAM 180 will a message informing the DAC NET the ZAM 180 has turned on the local It is also possible to activate the local input on the control via CAN bus speaker lines are individually for open and short circuit fault is detected in common for speaker lines on each ZAM 180 speaker lines are supervised in the inactive and active state The must be AC coupled CC 5 OR PSX 12 Input 2 Blocks Controls and Indicators and Indicators ZAM 180 has one Reset button diagnostic LEDs level adaptation of the local external audio input and CAN address switches one terminal block two terminal connections and 60 pin flat ribbon connections as shown in Figure 2 reset switch is located on the top of the front panel Pushing the reset re initializes the ZAM 180 operation Edition 10 315 035600 10 LEDs functions are defined as follows NORMAL NORMAL IN OFF NORMAL STATE for failure on PSC 12 CC 5 wiring fail FAIL on

terminals are used for field wiring as in Figure 12 14 Input terminal block is non power limited and supply up to 12A This Input is connected the output terminal TB4 of the as shown in Figure 11 Edition 10 315 035600 10 ZAM 180 takes one sub address on the DAC NET To configure the CAN use the two rotary switches on the front panel refer to Figure 2 screws as shown in Figure 3 on the left and the right side of the housing and remove the front plate screws for the front plate screws for the front plate 3 Position Of The Securing Screws setting the speaker line voltage and the low frequency cutoff see 4 4 Position Of Connectors And Jumpers For Setting The Speakerline Voltage And The Low Cutoff Edition 10 315 035600 10 the Speaker Line Voltage amplifier supervision has to be configured for the appropriate line too Amplifier supervision is configured with jumpers on header X28 Line Voltage 70V in the coded connector in the position marked 70 V set Jumper X28 position 2 3 5 Jumper Position 70V Line Voltage 25V in the coded connector in the position marked 25 V is No jumper on X28 100V 100V the low frequency cutoff 6 Jumper Position 25V frequency cutoff can be set for 240Hz or 110Hz This setting acts on local audio input and on all digital channels for 240 Hz protects small speakers from being overload with bass Speech intelligibility may be improved This setting is not for higher quality music reproduction For 520 Hz low frequency usage use the 110 Hz setting Set no jumper on X21 For 240Hz low frequency cut off two jumpers have to be set set only one jumper 7 Jumper
