Distributed Audio Panel ACC-25/50DA & ACC-25/50DAZS Instruction Manual Document 52265 6/8/2010 Rev: P/N 52265:B1 B1 ECN 10-278
Fire Alarm System Limitations While a fire alarm system may lower insurance rates, it is not a substitute for fire insurance! An automatic fire alarm system—typically made up of smoke detectors, heat detectors, manual pull stations, audible warning devices, and a fire alarm control panel with remote notification capability—can provide early warning of a developing fire. Such a system, however, does not assure protection against property damage or loss of life resulting from a fire.
Installation Precautions Adherence to the following will aid in problem-free installation with long-term reliability: WARNING - Several different sources of power can be connected to the fire alarm control panel. Disconnect all sources of power before servicing. Control unit and associated equipment may be damaged by removing and/or inserting cards, modules, or interconnecting cables while the unit is energized. Do not attempt to install, service, or operate this unit until manuals are read and understood.
Software Downloads In order to supply the latest features and functionality in fire alarm and life safety technology to our customers, we make frequent upgrades to the embedded software in our products. To ensure that you are installing and programming the latest features, we strongly recommend that you download the most current version of software for each product prior to commissioning any system.

Appendix A: Digital Voice Messages The ACC-25/50DA FC-MGM module provides a 60 second record time which allows for a single fire message of 60 seconds length, two 30 second messages, three 20 second messages or four 15 second messages, which may be field programmed. Refer to Section 4.1.1, 'Record Push Button (on optional FC-MGM Module)' on page 52. The FC-MGM is provided with a factory recorded single ‘primary’ message which can be changed in the field.
Appendix B: Addressable Module Connections When configured with an addressable FACP such as the MS-9200UDLS, MS-9600(UD)LS, MS9200UD, MS-9200C(E), or MS-9600, the ACC-25/50DA may be triggered either by an FACP main NAC output or from addressable control modules. Figure B.1 illustrates CMD1 triggered by an addressable control module. The addressable control module may trigger the ACC-25/50DA via reverse polarity (shown) or relay contact.
Appendix C: Wiring Requirements Connecting external system accessories to the ACC-25/50DA main circuits must be carefully considered to ensure proper operation. It is important to use the correct type of wire, wire gauge and wire run length per each circuit. Refer to the following table to specify wire requirements and limitations.
