Siemens Industry ZAM-180 Zone Amplifier Module

Siemens ZAM-180 Zone Amplifier Module is a 180-watt CAN-bus audio amplifier designed for Cerberus PRO Modular fire-alarm systems, combining two speaker zones with a single amplifier in one compact module. It delivers 150 W at 25 VRMS or 180 W at 70 VRMS, depending on the system configuration, and connects to the DAC NET via the CAN bus to receive control data and audio channels. The unit occupies one module space and mounts on a back box or on the CAB MP mounting plate, supporting Style Y and Style Z speaker wiring configurations and 25 V/70 V distribution for scalable voice-evacuation or paging. Up to eight digital audio channels can be transmitted from DAC NET through the module’s digital audio bus, enabling coordinated multi-zone announcements, while speaker lines are supervised for opens, shorts, and ground faults in both active and inactive states. The ZAM-180 is listed for indoor use under UL 864, 9th Edition, aligning with life-safety installation standards, and is identified by ordering data 500-035600 (70 V) with the S24235-B6-A5 designation for 70 V operation. This module is intended to be used within Siemens’ Cerberus PRO architecture, providing reliable, supervised amplification and zone control for emergency voice communication and background paging in commercial environments.
