Installation Instructions

Model ZAM-180

Zone Amplifier Module 180W (500-035600 / S24235-B6-A5 (70V))

Installation Instructions for North America

INTRODUCTION The Model ZAM-180 from Siemens Industry, Inc. is a CAN data bus module

that contains two speaker zones and one audio amplifier, capable of operating

at 25 (150W) or 70 (180W) VRMS.

The two speaker zones can be wired

and operate as either a single Class A

zone or a single Class B zone or as

two Class B zones independently

protected to provide split zone or

interleaved speaker zones.

The ZAM-180 can also be used as a

backup amplifier to serve as a backup

for other ZAM-180 amplifiers in a 1 to

1 backup or 1 to many backup.

The ZAM-180 mounts at the back of

the enclosure of the system and

occupies ¼ of the total space of the

Mounting Plate.

Features ZAM-180 features are as follows:

•

Digital (Class D) audio power

amplifier with 180W RMS

output power

• Over all efficiency about

80% under full load

• Amplifier is supervised for

functionality

• Amplifier is protected against

open, short circuit, over

current and over modulation

OPERATION • Speaker lines are supervised for open, short circuit and ground fault • The ZAM-180 is micro controller controlled • A FPGA controls the digital audio data stream (ASI Bus) transmitted by the DAC-NET • SW update via PMI/PMI-2/PMI-3 (XLS), FCM2041-U2 (Desigo Fire Safety Modular), FCM2041-U3 (Cerberus PRO Modular) The ZAM-180 receives its control and communication data from the DAC-NET and sends its status data to the DAC-NET via the CAN Bus.

PRE-INSTALLATION The ZAM-180 takes one sub-address on the DAC-NET. To configure the CAN address use the two rotary-switches on the front panel (refer to Figure 2) Remove screws as shown in Figure 3 on the left and the right side of the ZAM-180 housing and remove the front plate. Securing screws for the front plate Securing screws for the front plate Figure 3 Position Of The Securing Screws For setting the speaker line voltage and the low frequency cutoff see Figure 4.

Setting the Speaker Line Voltage The amplifier supervision has to be configured for the appropriate line voltage, too. Amplifier supervision is configured with jumpers on header X28. 1 1 Plug in the coded connector in the position marked 70 V. and set Jumper X28 position 2-3. 1 Speaker Line Voltage 70V 70V 25V 100V X28 1 2 3 Figure 5 Jumper Position 70V 1 1 Plug in the coded connector in the position marked 25 V. There is No jumper on X28.

After having done these pre-installations install the front plate and secure it again. INSTALLATION Remove ELECTRICAL POWER prior to working on equipment. Figure 9 Location Of The ZAM-180 On The Mounting Plate The ZAM-180 can occupy any position on the mounting plate (Refer to Figure 9). When the ZAM-180 is mounted correctly on the Mounting Plate it will be flush on the top, bottom, and right with the Mounting Plate and the mounting screw holes of the PSC-12 will align with the threaded posts.
PAGE 7
1. Install four M5 screws in the threaded posts at the mounting position. Screw each of the M5 screws into the threaded posts 5-6 turns. 2. Place the ZAM-180 over the four screws on the Mounting Plate and slide it down or towards you to rest on the four screws. (Refer to Figure 10.) When the ZAM-180 is in the correct position it will be flush with the top, bottom and right side of the Mounting Plate. 3. Tighten the four screws. WIRING Remove ELECTRICAL POWER prior to working on equipment.

Speaker Line Wiring The configuration of the speaker lines is selectable between Class A, Class B, or 2 x Class B. NOTE: For U.S. installation only, reference to Power Limited is deemed Class 2 and reference to Power Limited 70V speaker circuits is deemed Class 3. Class 2 and Class 3 designations do not apply to Canadian installations. Please refer to the appropriate product installation instructions for further details. Class A: The speaker line is looped back to the system.
PAGE 9
Class B: A configuration, where the end of line resistor is at the end of the speaker line. The ZAM-180 is capable of single Class B wiring if the unused speaker line is connected to an EOL . NOTES (Speaker Lines and Backup Amplifier) 1. Use twisted pair or shielded twisted pair. 2. Terminate shields at one end only. 3. Supervised and not power limited. 4. Positive or negative ground faults detected at <10k Ohms for terminals 9-10.
PAGE 10
2x Class B: Both lines are used and have the end of line resistor at the end of the speaker line NOTES (Speaker Lines and Backup Amplifier) 1. Use twisted pair or shielded twisted pair. 2. Terminate shields at one end only. 3. Supervised and not power limited. 4. Positive or negative ground faults detected at <10k ohms for terminals 9-12.
