A.1 Correlations
Setup and configuration of an addressable system is different than a conventional system. In a con-
ventional system, assignment of input devices (smoke detectors, pull stations, heat detectors, etc.)
to zones is accomplished through wiring. The wiring is direct from clearly marked panel terminals
to any device assigned to a particular zone. Connection of output devices (horns, bells, strobes,
etc.) in a conventional system is accomplished by direct wiring of the output devices to Notification
Appliance Circuit terminals.
In an addressable system, a minimum of a single pair of wires (SLC communication loop) is used
to connect all addressable input and output devices. Communications between the FACP (Fire
Alarm Control Panel) and all addressable devices takes place over the wire pair which originates
from the FACP. Software programming is used to configure the system as opposed to direct wiring.
Zone assignments are created via software means, hence the term software zones.
Setup of an MS-9050UD software zone is accomplished by panel programming. Each addressable
device can be assigned to a maximum of five software zones. Each software zone, however, may
have from 1 to 50 addressable input and output devices assigned to it.
Monitor modules, control modules and detectors comprise a group of 50 addresses, each device
having a unique address from 1 to 50. Be careful not to duplicate addresses between devices.
Refer to the following page for an example of zoning.
In the example on the following page:
• Zone 01 has the following addressable devices assigned to it:
SD355 smoke detectors with addresses 01 and 02

MMF-300 monitor module with address 03

MMF-302 monitor module with address 04 and 05

CMF-300 control modules with addresses 06, 07, 10, 11, and 13

• Zone 02 has the following addressable devices assigned to it:
MMF-302 monitor module with addresses 04 and 05

CP355 smoke detectors with addresses 15 and 16

CMF-300 control modules with addresses 20, 11, and 21

• Zone 03 has the following addressable devices assigned to it:
SD355 smoke detectors with addresses 22, 24, and 25

MMF-302 control module with address 30

CMF-300 control modules with addresses 11, 31, and 32

The example points out some of the key assignment features of the MS-9050UD. Addresses of
detectors, monitor modules and control modules are not duplicated. The control module with
address 11 is assigned to three software zones (providing floor above and floor below). Be careful
to properly plan the installation prior to installing any devices.
